So just digging into 2016 a little bit further. I talked about that we had record net income of $44.7 million. And what you'll see is that represents about $3.5 million of an increase in net income for the year.
The biggest part of that coming in the fourth quarter. Notice in the fourth quarter, we had net income growth there of about $3.2 million. From an EPS standpoint, Mike talked about our EPS is up 5.1%. You'll see that was a $0.14 increase for the year. $0.17, in effect, came through in the fourth quarter, and so overall, once again, a very positive year. It was growth both in terms of our regulated businesses as well as our unregulated businesses. We had growth in gross margins for both, which we'll talk about in just a minute.
So in terms of our Regulated Energy segment, we had an increase of $17 million in regards to gross margins for the year that ultimately resulted in about $8.9 million because of expenses to support that growth hitting the operating income line. There were various different avenues that this growth came in across the board. The first thing -- service expansion. From a service expansion standpoint, we increased there about $7.2 million in terms of gross margins, principally a large result of the interim services that we provided to a power plant here in Delaware.
Secondly, we added $4 million from a gas reliability replacement program. That's been in place for several years under Jeff's leadership. And that particular program, we've invested over $100 million in capital expenditures, $26 million this last year, and we've replaced about -- over 210 miles of pipes in the state of Florida.
We added another $2.7 million from what we call organic growth. On the Delmarva Peninsula, that was about $1.5 million of that $2.7 million, and that came primarily from both residential and commercial growth, with residential being more than 50% and that growth rate being about 3.4%. In Florida, we added $1.2 million primarily from commercial customers, those representing that $2.7 million that I mentioned.
We had a Delaware division rate case during the year. Rates went into effect on an interim basis in February, so we have 10.5 months of rate relief from Delaware from the new rates in the year. That represented $1.5 million, a partial year in total. On an annualized basis, it will be $2.25 million.
We generated $1.4 million in terms of services related to Eight Flags, our natural gas transmission, our intrastate pipeline in Florida and also our distribution system at FPU. Both of those delivered natural gas that enabled our CHP plant to operate beginning in June.
And then lastly, we've been in a conversion process both in Ocean City -- or excuse me, Ocean Pines and West Ocean City, and we've done quite a few conversions to date, and that added about $736,000. And just over a week ago, we announced that we had finally gotten natural gas to Ocean City itself, and so we'll be getting a conversion process there.
On the unregulated side, what you'll see is that basically, we had gross margin growth at the top of $4.6 million ultimately because of the weather and the expected -- we had expected lower retail margins per gallon on the propane side. Ultimately, that growth was masked by those 2 factors. And on the unregulated side, the results were down slightly for the year.
For the positive gross margin aspects that we experienced, first, in our Aspire Energy of Ohio business, our gross margin was up by about $5.9 million, really as a result of 2 things: one, 2015 only included 9 months of results because we acquired the business on April 1; and then second, as a result of some amendments to some contracts we made in terms of pricing, customer growth that was in excess of 10% and then also some additional fees that were placed into service. So ultimately, $5.9 million from Aspire. In addition, our Eight Flags CHP plant went into service in June. That added $3.6 million, coupled with, I talked earlier about on the regulated side, another $1.4 million. So in total, $5 million for a partial year from that plant.
Our PESCO operation, which is our natural gas marketing operation, also added $1 million because of new contracts and new services that they provided in their FERC areas as well as they've expanded also into Ohio. Also in the increases I talked earlier were anticipated lower retail propane margins; the weather, which we'll talk about in a few more minutes; and then lastly, lower gross margins from Xeron.
When we look at it on an EPS basis and reconcile it year-over-year, turning to Slide 10, what you will see is that the gross margin that I talked about was about an $0.83 increase year-over-year, which was offset by expenses to support that growth of about $0.44. Weather represented $0.15, so it negatively impacted the year's results by $0.15. We talked a little bit about Aspire. It added $0.09. And we did an equity issuance in September, and that represented basically about $0.05.
Moving on to Slide 11. This just actually lays out those gross margin components that I talked about earlier. So those projects, in effect, added in total about $24 million for the year. Those projects are also going to have an incremental effect in 2017 that we've laid out here. And so they are going to add approximately $5.2 million additionally, above what they contributed this year. And then there's also some projects that are in the pipeline, so to speak, for completion that will add slightly to '17 but on a larger basis in terms of 2018.
So this includes the system reliability project, which we're in the process of constructing and will have complete by the 1st of April. Our assumption here in the projects and initiatives underway is that project, we will get rate recovery as part of the rate case that we're currently involved in. And so we've got a partial year of about -- almost $2.3 million. The other project that is being factored into here is our 2017 expansion projects, which, when completed, you will see will add an incremental $17 million, coupled with the system reliability project next year.
To talk a little bit about the 2017 expansion project, it's the biggest project that we've done in our history in terms of a project from the ground up. With that project, we are meeting our customers' demand to bring low-cost, reliable clean energy, more of that to the Delmarva Peninsula. What it will do for us as a whole is to increase our FERC transportation deliverability by about 25%, and we're meeting the needs of customers. There's about 5 customers, one of those being ourselves, our distribution entities, our 3 distribution entities. We made our initial filing with a prefiling in May of last year. We filed our CP application in December, and it's currently, right now, sitting before the FERC.
Our goal, moving to Slide 13, is that, that project would be, hopefully, be approved by the FERC in May, and we would begin construction shortly thereafter and complete by the end of the year, with the margin most likely beginning in 2018. The margin is $15.7 million from this project. It will represent an additional 61,162 dekatherms, which is about equal to 60,000 customers, normal residential customers that we serve today. On the Delmarva Peninsula, we currently serve about 74,000 customers, so this is a pretty significant project when you look at it from that vantage point. It's just shy of being a $100 million project, so very significant, once again, overall.
To be able to finance that project and to also support the other projects that we're looking at right now and be able to finance those on a go-forward basis, it's been very important to us to have the balance sheet that can support that growth. And so if you look at our balance sheet today, our total capitalization is about $805 million. Comparing that to 2012, we were at about $428 million.
On an enterprise value, as a company today, we're just shy of $1.5 billion overall, but we've had access to the equity market. Just last year, we did an equity offering in September. We have capacity under some of our existing debt agreements. Right now, we utilize lines of credit. We have a revolver. And in total there, we still have another $180 million that we can access there to support our growth.
We also have a shelf facility with Prudential. We're accessing part of that in April to do a long-term debt placement of $70 million, so that leaves another $80 million. And so we're constantly looking at what ways can we continue to add additional access to capital to support our growth. In addition, I mentioned the equity. Our current equity to total capitalization is about 55% at the end of the year. So very important to us.
And now I'm going to turn it over to Mike, who's going to talk about our strategic platform for growth.
