Chiara Valentini

Management

Thank you, Chantal. Good morning everyone and welcome to TransAlta's Third Quarter 2019 Conference Call. With me today are Dawn Farrell, President and Chief Executive Officer, Todd Stack, Chief Financial Officer, John Kousinioris, Chief Operating Officer and Brett Gellner, Chief Development Officer. Today's call is webcast, and I invite those listening on the phone lines to view the supporting slides that are currently available on our website. A replay of the call will be available later today and the transcript will be posted to our website shortly thereafter. As usual, all of the information provided during this conference call is subject to the forward-looking statements qualification set out here on slide 2, detailed in our MD&A and also incorporated in full for the purposes of today's call. All amounts referenced during the call are in Canadian currency unless otherwise noted. Non-IFRS terminology used including comparable EBITDA, funds from operations and free cash flow are also reconciled in the MD&A for your reference. On today's call John and Todd will work through the quarterly and year-to-date results and expectations for the remainder of the year. In addition, we will provide commentary on our recent announcements and how these advance our clean energy investment plan and growth strategy that we outlined at our Investor Day back in September. After these prepared remarks we will open the call for questions. And with that, let me turn the call over to Dawn.

Dawn Farrell

Management

Okay thanks, Chiara and welcome everyone to the call today. We're pretty excited to be here announcing our third quarter results. We did have a strong third quarter and we're pleased with the results across all of our businesses. And of course strengthen in the third quarter has given us strong performance year-to-date and it's increased our expectations for annual performance. Now overall, our operational and financial performance is tracking to deliver a strong year, our clean energy investment plan and growth strategy is on track and through the quarter, we had key milestones, which I think has been very impressive in terms of what the team has done. And finally, we successfully concluded the final leg of our Santa DPA arbitration and collected an additional one-time payment of $56 million from the balancing pool, which is great news, because that has added to our cash flow for the year. So I'm going to just start with a couple of overall comments on our financial performance and of course Todd will get into more of the detail. We earned a total of $305 million of comparable EBITDA in the quarter due to strong performance at our Canadian and U.S. coal businesses. Our energy-marketing segment -- from the efforts and the work that's been done across the company to reduce our OM&A costs and of course because of the one-time PPA payment. Now if you take out the one-time PPA payment, our EBITDA was flat for the quarter relative to last year. Now what's important here is that the Mississauga and popular Creek contract changes that occurred at the end of 2018, we're expected to reduce our EBITDA in the quarter by approximately $30 million. So, to be able to deliver flat year-over-year EBITDA with these changes shows that we've been…

Todd Stack

Management

Thank you, Dawn. And welcome to everyone on the call. Before I jump into the financial and operational results, I would like to start by reviewing the Alberta and Mid-C power price trends and what we're expecting for the remainder of the year. In Alberta, power price during the quarter was weaker when compared to last year, primarily due to a cooler than normal summer in the province, which reduced the number of high load days. The average price in the third quarter was $47 a megawatt hour compared to $55 per megawatt hour in 2018. Even with the lower average market price, our merchant coal assets performed well and we are able to realize the power price significantly higher than the average pool price. For the remainder of 2019, forward curve is in the $58 per megawatt hour range, however we are highly hedged with approximately 85% of our expected production in Alberta hedged for Q4. For the full-year 2019, we expect power prices to average approximately $57. As we look at 2020, the final year where Alberta assets will be under their PPAs. The forward curve is around $55 per megawatt hour, which is supportive of our merchant fleet in the province. The Mid-C price in the Pacific Northwest settled at U.S. $28 per megawatt hour for the third quarter compared to $46 per megawatt hour in 2018. Pricing in 2019 represents a more normalized level whereas 2018 was positively impacted by a very strong demand in the U.S. West region. For the balance of 2019, production of Centralia facility is about 85% hedged. Slide 9 breaks down the performance of our Canadian coal fleet and helps highlight the benefits we are seeing from decisions made in 2018. While overall revenues and productions were lower in Q3 compared…

Dawn Farrell

Management

Great. Thanks, Todd. So I've got a short summary. So short wrap up here. In summary, I would like to conclude with my perspective on our execution plans and the advances we've made on our re-powering. The acceleration of the combined cycle unit at Sundance Unit 5 is a great example of how having a focus and clear strategy allows us to take actions that enhance our plan and shareholder value by capitalizing on market opportunities as they present themselves. The proceeds from the Brookfield investments on earlier this year. Provided funding flexibility, which was demonstrated by our opportunistic purchase of the equipment from QinetiQ core. We also see enormous value in having a long-term hedge with a credit-worthy counter party as an excellent addition to our portfolio. This enhances the financial flexibility of the company and we do believe that investors and creditors value of portfolio that has a portion of the cash flow is locked in as these projects come on stream and into the market. The Sundance 5 recurring is now larger than previously assumed. And so it does bring forward future cash flows. Keephills 1 is now more likely a candidate for a simple conversion in 2022 and it will still be permitted for a combined cycle unit in the mid 2020. We showed you at Investor Day 2 simple boiler conversions have very short payback and that will be even shorter if the carbon levy escalates with the current expectations under the federal policy schedule. We look forward to providing further feedback in late January, in terms of our annual outlook and guidance. Overall, I'd like give many, many thanks of the team and our employees, they worked extremely hard through the quarter. You see the results and you see all the milestones they achieved and they are just moving everything ahead for this company. So, thank you. And with that I'm going to turn it back over to Chiara.

Chiara Valentini

Management

Thank you, Dawn. Chantal would you please open the call for questions from the analysts and media?

Operator

[Operator Instructions] Your first question comes from Rob Hope with Scotiabank. Your line is open.

Rob Hope

Analyst

Hello, everyone. Thanks for taking my questions. First question is on Canadian Coal, just wanted to dive a little bit further into the fuel and purchase power savings that you're getting there. Is there a way to quantify the benefit that you saw from Pioneer in Q3 and then as we look into Q4 and 2020. Is it fair to assume that absent moves in gas pricing that we could see on a per megawatt hour basis similar fuel and purchase power costs moving forward?

Todd Stack

Management

Yes, it's Todd here, I don't have a specific number for you, but the trend that you saw over the summer, I would say we're going to increase the volumes significantly in 2020 over the amount of co-firing as that contract steps up to the full capacity of about 130 MMBTUs per day. So we'll see more coal firing. We did see very attractive prices on gas over the course of the summer, which did help during that period. Over the course of the winter, we've actually procured a fair amount of our gas needs over the course of the winter, but as you know the pricing on gas shifts quite a bit between summer, and winter profiles. So, I think you'll continue to see definitely savings trends from both the fuel cost as well as the avoided emissions costs as we go into 2020.

Brett Gellner

Analyst

Yeah. And the only -- it's Brett. I mean just simply on a carbon basis if you take a typical coal unit at $30. I think it's about 18 bucks a megawatt hour. And then when you're burning gas, I think you're closer to 6 bucks. And so, a difference of about $12 per megawatt hour on -- got the gas portion. So, if you think about burning kind of 139 TJs a day in around that zone just co-firing, that is the carbon saving here multiplied convert that into a megawatt hour. And you can get the savings.

Dawn Farrell

Management

So Rob, did that help?

Rob Hope

Analyst

Yes, that's great. Thank you.

Dawn Farrell

Management

Okay.

Rob Hope

Analyst

And then more broadly speaking, we've seen you move forward with SemCAMS on a co-Gen, we've seen Suncor do one as well as Pembina do a small co-Gen as well and speak about further Cogent. How are you thinking about increasing behind the fence generation and how it would affect forward pricing and kind of the overall supply demand mix in Alberta?

Dawn Farrell

Management

I mean we've seen, if you go back and you look at loads growth in Alberta and you look at how it's been supplied, I mean it's a lot of load growth from 2000 until 2019 was supplied by a combination of investments that we made and the co-generation. So as we look ahead, our models to incorporate a lot of co-generation going forward as we set our forward prices and think about our investments, just remember that 99.9% of what TransAlta is doing is replacing existing supply and we've actually taken supplier of the market. So because we've shut down Sundance units 1 and 2. So -- we don't, so as we look at our estimates of pricing we incorporate in co-generation, I mean you can sometimes it's half and half in terms of two-thirds, one-third in terms of how new growth is supplied. But you really have to look at where the developments are in the province, you have to look at who can add co-generation, yes, you have to assess that against the ISOs plan for growth in our plan for growth. But net-net, Alberta has been supplied significantly by coGen and it's a great way to supply the market here.

Rob Hope

Analyst

All right, thank you. I'll hop back in the queue.

Dawn Farrell

Management

Great, thanks Rob.

Your next question comes from Robert Kwan with RBC Capital Markets. Your line is open.

Robert Kwan

Analyst · RBC Capital Markets. Your line is open.

Great, thank you. Maybe I'll just kind of continue on the co-gen side. I'm just wondering in your kind of detailed modeling and expectations, how much co-gen, do you think is that will be developed is going to be meeting new demands are associated with as we've seen with new industrial facilities versus co-gen we're seeing being built to meet existing demand effectively taking them off the grid?

Dawn Farrell

Management

Yeah. Robert, we see that is proprietary information. So we don't share that kind of detail with the market. I mean, if you -- you can, I think EDC potentially have some -- there that you can look at its public banks…

Todd Stack

Management

Yeah. Robert, the ISO just published their long-range plan and I think it's a good source, because I think they try to predict what the mix will look like, but you'll see, they've got pretty good growth still projected and more combined cycle coming into serve that growth.

Dawn Farrell

Management

Yeah, just broadly, if you want to think about the decision-making now, when I think about the last 20 years. I mean it's been here the whole time. What I've noticed about the co-gen is an incremental capital decision by an oil and gas company, so you have to be a company that has significant cash flows that you have nothing to do with to want to allocate capital over there. We do find that people will start with pretty large ambitious projects and then over time they narrow down as they get closer and they start with I'm going to do it all myself over time they tend to go look for a partner in co-generation. So when I'm doing the analysis or when we're doing analysis with the team, we do our risk assessment of every project based on the actual underlying cash flow of the company. And I mean, all else being equal most oil and gas companies would be putting their capital towards what they do best and the returns that they get out of their business and it's a secondary impact, but that's been the trend over the last 20 years that could change in the future but that's how we look at it got it.

Robert Kwan

Analyst · RBC Capital Markets. Your line is open.

Got it. If I can just finish on the ISOs market power mitigation proceedings and just your thoughts after looking at others of submissions it seems like many were supportive of the current framework like you were, but there were also I wonder if you can comment also specifically on a couple of submissions talking about dealing with single participants on a one-off or case by case basis?

Dawn Farrell

Management

I'll try not to say what I want to say on this, but I think at the end of the day, when I look again, when I look back over the last 20 years, there have been situations where the buyers in the marketplace had significant market power and the Alberta market adjusted to that using their feedback regulation and using the OPEC and a number of different ways to ensure that we had an efficient market through the whole for the last 20 years. So my belief is that if you actually look at kind of a light touch here, we've already got in place all of what's necessary to ensure that participants don't engage in market power behaviors. We also have an obligation under fee ops to make sure that we a positive obligation to make sure that we're not doing anything that would with expect market power. So that's an important thing for TransAlta and we've got the value set in this company to accrue to that as you know. So I think and I don't know what to expect, you never know what regulators are going to do, but I do know that if people participated market power behaviors here in the market they will be investigated by the MSA number one, and number two, they will keep prices in a range that will bring on more supply. So I don't know why they would do that and I think we've had 20 years of experience, creating a competitive market with a robust on spot market price. And so I have a lot of confidence that the market works today.

Your next question comes from Mark Jarvi with CIBC Capital Markets, your line is open.

Mark Jarvi

Analyst · CIBC Capital Markets, your line is open.

Yeah. Hi, everyone. Maybe just want to talk a little bit on the shift in the Sundance repowering two questions I guess is, one is the CapEx per megawatt goes up, partially offsets to preserve the returns. You guys talked about the Investor Day. And then any incremental views on what to do with Sundance 3 and 4?

Dawn Farrell

Management

So I'm going to turn it over to Brett.

Brett Gellner

Analyst · CIBC Capital Markets, your line is open.

Yeah, I mean to, as Dawn mentioned, this really helps us to some extent advance with the opportunity. So we see that as return enhancing. But at the same time remember by getting and a long-term contract here provides a lower risk investment to for us and we think that's very positive. And so when you blend all that together, we see the returns still very attractive from a risk adjusted basis. In terms of the other units, we're still no change from what we communicated at Investor Day, we'll still evaluate those come into the new year -- next year and you know it's fundamentally really on the outlook for the market fundamentals, but also as Dawn says, just the payback on some of these, as we said at Investor Day is pretty high on simple conversion. So we'll take next year to evaluate that and keep you posted.

Dawn Farrell

Management

Yeah, I'd say much a couple of things from my perspective. So having been in the business a long time I tend to be a proponent of those workhorse type machines that the out costs are, they're excellent to operate, they're stable and they have a -- and when you look at, when you look at the overall life of contract and you look at the maintenance cost to go along with those machines. They're typically lower than some of the newer issues that may have a slightly higher key rate but are much more expensive to maintain. So, that's one day. Number two, remember, we have a portfolio, so we can actually do something like this and then do a different kind of configuration at a different plant. And when you blend everything together and you run the math, we get, we get some benefits out of the diversification and we do get significant benefit side of having two machines on one steam turbine. So that allows us some dispatch capability as well. I think the final thing is, if you look at the Federal rules on carbon tax for the province here to stay in compliance with the Federal Program and of course we just had, we just got an election here. We know what the Federal Program is going to look like at the Federal Program goes from $30 to $40 to $50 by 2022. So getting on gas sooner and saving greenhouse gas reductions makes a huge difference. Overall, these machines are here, they're built, they're ready to go, that make -- that significantly reduces construction risk and execution risk. So we factored all of that into our decision making.

Mark Jarvi

Analyst · CIBC Capital Markets, your line is open.

Okay. And then, is there any other sort of additional benefits of doing that transaction by those turbines by essentially potentially getting those out of the hands of someone else you might have build more capacity, the market was that all in sort of the motivation for that deal?

Dawn Farrell

Management

Well, no, not really. I mean at the end of the day, we would only -- we could only the pricing for those assets that would work in our portfolio. So at the end of the day, I don't know what they were planning on doing. I didn't really care. I just know that Brett and his team had a had a bit of a sense that this was a way to accelerate our program and the Connecticut guys. I think saw that as the best opportunity.

Mark Jarvi

Analyst · CIBC Capital Markets, your line is open.

Okay. And then we've seen some commentary and some deals around either merchant or corporate PSPAs for wind or solar in Alberta. In the past you guys have indicated you think merchant when was great for just how you guys seeing more financing your business and funding growth. But what about the prospects of finding commercial industrial off takes for renewables in Alberta, is that something you guys see is increasingly something you could work towards?

Dawn Farrell

Management

Yeah. Listen, we've had a team that's been talking to people quite a bit on that. We already have quite a bit of merchant wind, we don't need to add to our merchant wind portfolio. And as you saw from the tier, we now have some additional revenues coming in because of the carbon offsets that they provide and we've got some of the best wind that there is really and we'll have Windrise coming on and all the rest of that. So my view is the team talked to industrial customer here and if there is opportunities to build for people we would do it, we would encourage them not to build new and to use some of the existing because it does have a -- it's good wind and it was built a good time is kind of good cost structure, but net-net and we'll see what I know is if you build more wind in Alberta, you're going to need our coal to gas because the wind both here are pretty well at the same time and you need to back it up.

Mark Jarvi

Analyst · CIBC Capital Markets, your line is open.

And my last question is maybe around TransAlta renewables and dropdown, you talked about Skookumchuck and Windrise, is there an optimal timing around you guys would think about a transaction or any sort of the factors that go into how you think about sequencing dropdowns to TransAlta renewables?

Dawn Farrell

Management

Well, if we told you that we'd have to kill you. So there is always an optimal timing and you'll hear about it when everybody else does.

Mark Jarvi

Analyst · CIBC Capital Markets, your line is open.

Okay, thanks.

Okay, thanks.

Your next question comes from Jeremy Rosenfield with Industrial Alliance. Your line is open.

Jeremy Rosenfield

Analyst · Industrial Alliance. Your line is open.

I'll try not to ask any questions it'll get me killed. Just on -- thoughts on the supply cushion, Brett you referenced today so publishing the update and the supply cushion looks like in winter gets to be pretty tight, both this year and probably next year as well. So, any thoughts on your positioning the portfolio, looking forward for potential upside in trading revenue and that type of thing?

Brett Gellner

Analyst · Industrial Alliance. Your line is open.

Yeah, I mean, as always winter would be just given the load increases that go on. So yeah, we just, I mean there is no, I don't think any change to what we are -- they have been doing. Well position the fleet accordingly, we're really looking more long-term on the investments. So Todd, I don't know if he --.

Dawn Farrell

Management

Yeah. Maybe a way to think about it Jeremy is that Todd talked about it. I think our hedge portfolio was at 85% --

Jeremy Rosenfield

Analyst · Industrial Alliance. Your line is open.

Pretty highly hedged was down.

Todd Stack

Management

Yeah. Pretty highly hedged. But you'll see that it's not 100% hedged. And the reason, as you know is in Alberta being short of supply, when a whole bunch of coal plants decide to take a rest on a coal day is that disaster. So we tend to carry production into the year, in order to be able to withstand that. The second thing is, because we now have our Sundance 2 merchant, right. So they pretty well sit there and wait for those days and we have the ability to capture some of that, when it does occur if it does occur. Now you also have to remember it is Alberta, so we have that -- I think the wettest summer probably ever, coldest summer we've ever seen. Everybody is expecting really cold winter and you never know in Alberta, we could have the hardest winter ever. So anybody who thinks, I can tell you, I've looked at thousands of years of weather data, list the thousand. I looked for correlations all over the place and it's around a mark. So the supply cushion could be short under cold weather conditions and it could be fine, if the weather tend to be mild. And nobody knows what the weather will be.

Jeremy Rosenfield

Analyst · Industrial Alliance. Your line is open.

Okay. I'm hoping for weather for skiing, but anyway for -- if we look at the same thing looking farther out. So if you think about the merchant portfolio in Alberta from a long-term perspective, maybe 2025 and outward after your through all your boiler conversions after your through repowering. Is there a hard number or something somewhere where you want to get the portfolio in Alberta too. So from a long-term basis, so that you have some kind of the hedge position or long-term contracted position on a sustainable basis going forward?

Dawn Farrell

Management

Yeah. Yeah, you're thinking about the -- what we've got. You're thinking about the Shell contract which we want more of those in our portfolio. Is that what you're evaluating?

Jeremy Rosenfield

Analyst · Industrial Alliance. Your line is open.

Yes, correct.

Dawn Farrell

Management

Yeah, Yeah, you know, that's -- so as you know we're pretty conservative here and the management team tends to like long-term contracted assets even if they have slightly lower returns than merchant because that's our DNA, right. And so I would say that we've still got a lot more work to do. I wouldn't really want to give you any sort of -- you know I don't want to say something here that will go away and do some analysis on and then regret. But I would say having some portion of our fleet contracts that is going to be -- it's always going to be good, especially, I really like to have a portion of something hedged when it's coming online, because typically when parts come online at depresses the price a bit, so you kind of want to have some of that in there. I think the only thing that we have to do Jeremy is, there will be a lot of analysis on what Alberta looks like when there is more of -- when our fleet is more on gas, gas runs at higher availability and tends to -- it doesn't tend to have some of the same issues as banking cycle coal does, so we'll have much more operational flexibility when we get out there and I think if we mix the operational flexibility with our desire to have some consistent cash flows in our portfolio so that we have, so that Todd will be happy when he goes to finance bonds and will have lower rates on that, we'll be doing all that mix and more to come on tha. It will take a bit of time to think that all through. But in general if we could get other long-term contracts with large industrials that are creditworthy, you would see us trying to engage in those.

Jeremy Rosenfield

Analyst · Industrial Alliance. Your line is open.

Okay, that's great. I appreciate that. That's it from me. Thanks.

Your next question comes from Patrick Kenny with National Bank. Your line is open.

Patrick Kenny

Analyst · National Bank. Your line is open.

Good morning. Yeah, just back on the Sun 5 PPA, I know you can't provide too much detail. But I'm just curious in general, you know how you think about IRR for high quality PPAs in Alberta relative to building merchant, if you're going to be looking at potentially additional corporate off take agreements, who would you say is the fair spread and hurdle rate between merchant and contract?

Todd Stack

Management

Yeah, I mean it's a little tough to answer that because we do look at it truly from a portfolio and will always have a merchant component for example our hydro is a merchant to be able to capture those kind of peaks, but and you got to remember the contract is not unit contingent per se, even though you referenced So it's signed to the specific unit. But yeah, I mean I would say generally are going to look at probably 300 basis -- 3% higher for merchant. But again, it's a bit dependent on the technology, the age where it's situated, what market you're in, so that's just a broad rule of thumb.

Dawn Farrell

Management

Yeah, I would say take that 300 basis points as a bit of a mid point and think about it this way. The longer the contract, the fewer the base you might have. You might take even a bigger reduction. So more pass-through of costs, the more it's tied to actual heat rate of the machine. So there's a number of considerations there. But generally you pick up stability in your cash flows better financing costs, a whole bunch of things that you can plan around that kind of offset those reductions and returns.

Patrick Kenny

Analyst · National Bank. Your line is open.

Okay, thanks, that's helpful. And then you mentioned the lower gas prices in the summer having a positive impact on co-firing margins, I guess at the same time, it's reduced drilling activity in the central part of the province. So perhaps you could just provide a bit of an update on how you're thinking about ramping up volumes through Pioneer over the course of 2020, 2021, as well as just securing long-term supply through the other pipelines coming into Sundance Keephills?

Todd Stack

Management

Yeah. So we're, again, no real change from what we communicated at Investor Day. We're targeting to get up to that 350, 400 a day eventually once we're fully converted. We are well positioned here over the next year or so given the Tidewater Pipeline plus, we indicated, we have incremental firm capacity and the existing line there. And so, yeah, it's just a matter of working with parties. The drilling activity always ebbs and flows and we never saw the low prices being sustainable for the producers and that's not in our planning. So we do expect those to improve and drilling to be sufficient. And yeah, so we will as I said at Investor Day will keep you updated as we are progressing our plans.

Dawn Farrell

Management

Yeah. And I think Patrick, we are talking to a lot of guys as you can imagine, really our volume even though it seems like a lot of gas to us are -- there in that there in that rounding error of what Alberta producers in terms of gas, so that's helpful. What we do know is that this curtailment whatever they did with TransCanada this summer that alleviated some of the curtailment issue, so that the guys could get their gas into storage has helped to increase prices to get them closer to what you're seeing today. Those kinds of prices were what we had in our models. Because remember that, we're using gas and the offset is what we got [indiscernible] carbon. And so net-net, what we know from -- we've got gaps we've had gas guys on our Board and we've got John Dielwart on our Board. But as you get into this current pricing regime that we're seeing, the guys get out there drills again. So because they become more profitable. We're starting to see evidence of that.

Patrick Kenny

Analyst · National Bank. Your line is open.

Okay, that's great. Thanks. And then, just lastly on the NCIB, stock is up nicely here this morning. But still a little bit lower than where you've been in the market buying this year. So I just wanted to confirm that, given the extra free cash flow here in 2019 that the NCIB is still attractive in your view from a capital allocation standpoint?

Todd Stack

Management

No, you're absolutely right. It is an attractive price and as I mentioned in the earlier in the call, we plan to be back in the market here in Q4, as soon as we're out of blackout.

Patrick Kenny

Analyst · National Bank. Your line is open.

Okay, great, thanks guys.

[Operator Instructions] Your next question comes from John Mould with TD Securities. Your line is open.

John Mould

Analyst · TD Securities. Your line is open.

Good morning. Maybe starting with the SemCAMS co-gen project, it's shown as a potential drop down to RMW new deck. It's fully contracted on steam and I think half contracted on electricity. So does TransAlta Corp potentially take on that merchant risk and a dropdown scenario or are you comfortable with the co-gen going to RMW with some level of merchant exposure?

Brett Gellner

Analyst · TD Securities. Your line is open.

Yeah. John, we've -- as you can imagine, we've had some kind of early discussions with the Board of TransAlta renewables. So they understand the project in that there is a bit of a merchant component to it. And in general, we prefer a fully contracted assets at the TransAlta renewables level. But I wouldn't rule out the notion that having a modest bit. In a context of the whole portfolio of merchant power being available to -- being accepted by TransAlta renewables, given TransAlta Corporation's ability to manage and dispatch that into the market, is likely okay.

John Mould

Analyst · TD Securities. Your line is open.

Okay. And then just on the Shell PPA. I appreciate you don't want to detail individual contracts, but it's more broadly speaking, what's the minimum contract length you need to characterize an agreement as long-term?

Dawn Farrell

Management

It should be -- I thought -- I would say a medium-term contract is five years and anything longer than that is long term.

John Mould

Analyst · TD Securities. Your line is open.

Okay, helpful. And then just lastly on the U.S. coal results in the quarter, I know in your remarks you're pointed to strong unit availability. Can you just give a little more color on what drove that big gross margin increase in the quarter?

Todd Stack

Management

Sorry, I missed. Can you just repeat your question?

Dawn Farrell

Management

The U.S. results in the quarter was much better than--

Todd Stack

Management

Yeah. U.S. results. So, in last year we had a lot more unplanned outages. And so even though prices were high last year. The plant wasn't available to take advantage of high prices. This year, we saw strong pricing in around the $30 level in the plant had great availability in the quarter and really was able to capture those prices.

Dawn Farrell

Management

Yeah, I would say if you look at Centralia, and you look at our trading business, our trading business -- we have a lot of real-time traders and they arbitrage power from the north to California. And this year has this volatility that's occurred because of all the renewables in the California market but have to be back up has benefited both Centralia, and the trading business because their chipping away every day moving power all over the place. So that's been very helpful. I think as you look ahead, we know that unit one comes off at the end of 2020 plus, you've got a bunch of coal plants coming off in that region that all have been supplying base load power that has been sort of a nice complement to the hydro in the Pacific Northwest. I just think that there is a lot more volatility coming forward as we look at those markets. So we're starting to see for the first time some actual uplift as a result of that.

Yeah. But John specific to Todd's point, the specific answer was the amount of purchase power we had in Q3 of 2018 was significantly higher than it was in 2019. As we were able to supply a lot more, so we made it as opposed to having to buy in the marketplace. That's probably the biggest driver between the results quarter-over-quarter effectively on the comparative quarter basis.

Your next question comes from Chris Varcoe with Calgary Herald. Your line is open.

Chris Varcoe

Analyst · Calgary Herald. Your line is open.

Hi, my apologies, if this question's already been asked. But I'm curious Dawn, If you could tell me what are your thoughts on the government's new tier program, and more specifically how it's going to affect the company going forward?

Dawn Farrell

Management

Yeah, I mean I thought the tier program was well as expected and I think it's a good program kind of overall because what it does is it in enables companies like ours to make decisions like the ones that we've been making. There is a price on carbon, but there is also our performance standard. That performance standard is incredibly important for us in terms of -- already existing renewables, investments and also important in terms of making our coal to gas transition. So it's a good program. I'm really really hoping that it stays stable as we go forward, in terms of the performance standard. And I think the world is moving towards carbon being priced and we're ahead of the game here and we need to get credit for that.

Chris Varcoe

Analyst · Calgary Herald. Your line is open.

Can I ask you, what do you expect the financial implications if it will be in 2020 versus 2018 or 2019 in other words, will be paying more or less or the same under the program. And just to follow up on a completely different issue. Can I ask you what your outlook is on the electricity pricing in Alberta in 2020?

Dawn Farrell

Management

Yes, so the, it is the same, because it was, it was expected to be $30.37 performance standard. So there is no --

Todd Stack

Management

Which is the same standard in price that's currently in the market.

Dawn Farrell

Management

Yes, same standard of price, so the market expected. And then I -- the current forward price for electricity in 2020 is around --

Todd Stack

Management

In the $55 to $60.

Dawn Farrell

Management

$55, $55 to $60, which has been occurred, if you look back over the last 20 years on average Alberta trades in that sort of $60 -- $55 to $60 range. So it's a, it's a great, it's a great price for consumers.
