Thank you, Tony. Moving on to Slide 16. During the past several years, we've accomplished a major transformation of the company, from being primarily driven by non-regulated assets and earnings, to now being driven by much more stable assets and earnings, our strategic accomplishments over those last several years provide much more focus on our core Utilities, Power Generation and fuel production businesses, which in turn provide more stable future in cash flow and earnings as well as earnings growth for investors.
Slide 17 is just an update to our strategic initiatives timeline. This is provided to give you an estimated timing that was with regard to many of our key projects and initiatives.
Slide 18. Our clearly defined investment program will drive strong future earnings growth, with nearly $1 billion in capital spending plan for 2012 and 2013.
Slide 19 provides the detailed breakdown of our key long-term growth opportunities for the 2012 to 2015 timeframe. This slide doesn't include maintenance capital expenditures or other smaller projects, just primarily focuses on what we would deem large growth-oriented type projects. It's been updated also to provide a little more timing detail for you on some of the announced projects as far as which year those expenditures will occur and to what amounts.
Slide 20, regulatory approval in Colorado. We received approval from the Colorado Public Utilities Commission for the rate case associated with our new utility power plant for our Colorado Electric utility. Those rates, as I mentioned earlier, went into effect January 1 of this year, same day as commercial operations of the new power plant.
On other fronts in Colorado, we have an electric resource plan that we expect to file in the second quarter there. That resource plan will deal primarily with how we intend to meet the renewable portfolio standards in the state of Colorado having this completed 2 new power plants that need to do a lot of additional resource planning around baseload or peaking facilities, has been mitigated quite a bit. So that plan will focus primarily on renewables.
As I also noted earlier, we're still in the regulatory process on this proposed 88-megawatt turbine that we'd like to add to our Pueblo complex. That's the replacement facility for the W.N. Clark coal-fired plant in Canyon City, Colorado that we agreed to retire under the Colorado Clean Air Clean Jobs Act. We're in the process of working our way through the regulatory process there, expect a ruling from the PUC, hopefully, sometime this month, which will give us a little more clarity. We do have the right to own the replacement resource for the Clark plant, the 42 megawatts that we're losing there. So regardless of the outcome of this specific hearing, we do still have the right to own that replacement resource and we'll see how the regulatory process plays out over the next month or so here.
Slide 21. Our 2012 earnings growth is going to be driven largely by 2 new natural gas-fired generation projects that started serving our Colorado customers on January 1. I won't reiterate those 2 projects again, but I will reemphasize that we had an exceptionally short construction schedule on this facility, literally 18 months start-to-finish. The projects were completed on time, on budget and with a phenomenal safety record and excellent first month availability. So truly speak, volumes of the quality of our Power Generation, construction and operating team. They're literally world class.
Slide 22. We received approval during 2011 for and we're proceeding with our 29-megawatt wind project for Colorado Electric. As you can see, we're about halfway through the process of awarding construction contracts and procuring materials and expect to start construction soon as weather permits with the intent of having that facility completed and in service prior to year-end.
Slide 23, other regulatory updates. I mentioned previously that on November 1, Cheyenne Light and Black Hills Power filed a joint request for a Certificate of Public Convenience and Necessity to build a new facility, 132-megawatt project in Cheyenne, Wyoming. That generation serves 2 purposes. One is replacement of some older coal-fired generation in Black Hills Power that we'll have to repair under the new EPA regulations which I'll discuss shortly. And then also to meet ongoing demand requirements, particularly, in the Cheyenne, Wyoming area. We had initial hearing date set at the end of July on that CPCN, assuming approval, we would expect to have the plant completed and commercially available by the second quarter of 2014.
And then finally on December 1, Cheyenne Light filed an electric and gas rate case requesting an additional $8.5 million of increase in annual revenues there. That case is not related to the proposed new power plant. It's just related to cost increases. Since our last rate case in Cheyenne.
Moving on to slide 24. New EPA regulations governing air quality on power plants and industrial facilities have received a lot of attention over the last year or 2. Two of those rules have a specific impacts on our facilities. One is what's called the boiler MACT rules which covers small utility boilers and primarily industrial boilers. Those rules were effective May of this year with a March 2014 -- 2014 compliance deadline.
Based on those regulations, we anticipate retiring 3 of our smaller coal-fired units at Black Hills Power for a total of about 82 megawatts. All those facilities are 60-plus years old have little-to-no remaining book value and cannot be economically retrofit to meet the new pollution control standards.
As I mentioned earlier, we would replace those resources with the proposed gas-fired unit in Cheyenne and in Black Hills Power's proportionate ownership for that facility.
The new utility MACT rules which were issued on December 1 and we've yet to finalize publication in the federal register, which I think, is supposed to occur this month, will be effective in approximately 3 years. We're evaluating the impact of that final rule on our generation fleet. But our initial analysis suggests that only our Neil Simpson II coal-fired plant, which was placed in service in 1996, will require any additional upgrades to be compliant with those emissions standards. Still doing some preliminary engineering work on that, but estimate $30 million to maybe $50 million or a little more capital cost associated with bringing that facility into compliance. We'll provide additional details as we make decisions along the way on our plans to break that facility into compliance.
Slide 25 provides details regarding the impact of various new EPA air emissions regulations, provide that just for your information. I won't spend much time on it today.
On Slide 26, Oil & Gas update. We finished drilling and completing our 3 Mancos formation test Wells. Two in the Piceance Basin of Colorado and one in the San Juan Basin of New Mexico. This slide provides detailed well test information and reserve information for the 3-well drilling program. The well results have met our initial expectations and gross reserves averaged more than 6 billion cubic feet per well.
One of the 3 wells was not completed and tested in time to book reserves prior to year-end. But despite that, we still included a total of more than 42 billion cubic feet of gross reserves from the 2 producing Mancos wells and 5 offset proven undeveloped locations in our year-end reserve study. We do expect to book additional reserves associated with that third well sometime in this first quarter of 2012.
Moving on to Slide 27. As we've discussed previously, our 74,000 acres of Oil & Gas leases in the San Juan and Piceance Basin include nearly 460 potential Mancos formation drill sites, based on 160 acres spacing per well. Our targeted well cost for an ongoing Mancos drilling program were in the $1.30 to $1.40 per net in Mcf equivalent basis.
Our leases are held by production from other zones, and they won't expire as long as we maintain that production. So unlike other operators and many other shale place, we're not forced to drill sub economic wells, just to hold leases.
In the way of ongoing plans, in the third quarter of this year, we intend to commence a single rig drilling program in the San Juan Basin, targeting the drilling of 4 additional Mancos Wells before year-end. We probably won't have all 4 wells completed and producing by year-end, but hope to have at least 2 finished. We believe these wells will still generate an acceptable return on our investment even at current natural gas strip prices. They play a very important role in continuing to assess the very large potential opportunity we have with our holdings in the Mancos Shale.
Slide 28 is our 2011 scorecard. As a reminder, this is our way of holding ourselves accountable to you, our shareholders. At the beginning of the year, we try to set out our key strategic initiatives and goals for the year and then monitor our progress as the year progresses. We had an excellent year in 2011 completing many key objectives.
Slide 29 is a new scorecard for 2012, winning on our key goals for this year.
And finally, Slide 30, in summary for the year, 2011 was a very good year for us. We're very focused on serving our customers and building shareholder value. We refined our strategy and business mix. In the Oil & Gas the area, we announced a new strategy much more focused on some limited oil exploration in our Mancos shale development. And our coal mine, as I discussed earlier, we made the decision to discontinue train load-out sales and focus primarily on our mine mouth operations there, and we divested our Energy Marketing business or made a decision to divest our Energy Marketing business. During the year we had very strong execution on several key major projects that will drive earnings growth notably the 2 power plants in Colorado that will serve our electric utility there.
We also announced during the year over $300 million in new growth projects slated to be completed in the 2013 and '14 timeframe that will also help us drive strong earnings growth. We're very well-positioned to take advantage of future opportunities. So all of these things I think will help us provide solid long-term earnings growth and good shareholder return for our shareholders well into the future.
That concludes my remarks. I'd be happy to entertain any questions if anyone has some.
