Thanks, Beth. We've spent a fairly significant amount of time and effort over the last couple of years on our natural gas transmission businesses, both on Delmarva and in Florida.
On Slide 22, we talk a little bit about the current Eastern Shore Natural Gas projects, and we've highlighted a couple of them here. One is the 2017 project that you've heard a fair amount about into the last year or so. We are virtually complete with that project. We have a handful of things remaining to do, but most of it is -- is up and running at this point. It's about $117 million investment, 23 miles of pipeline looping, 17 miles of new mainline extension, some new compression. We increased the total capacity on the Eastern Shore system by about 26%. It is a project that really transforms, in many respects, our Eastern Shore delivery capabilities, and will allow both continued growth of our distribution systems at the end of the Peninsula, but also will allow for significant industrial growth as it develops on the Delmarva Peninsula.
We're also in the process of looking at what we're calling the Del-Mar Energy Pathway Project, which, again, pushes -- or will push additional gas farther south into the Peninsula, allowing us to serve emerging growth in Southern Delaware, and on the Eastern Shore of Maryland. That project is at FERC right now, and we are hoping for a speedy transition through FERC if we -- if that's possible to be that anymore. But we're hoping for that. We think we're -- we'll be successful there.
So those combined projects with an estimated capital investment of about $166 million through years '20, '21, and combined incremental margin that's close to $21 million a year.
On Slide 23. In our Florida Peninsula Pipeline business, we've also had several significant projects; we've listed 3 here. And the first is the Northwest Florida Expansion that we're in the Pensacola, Florida area, about a $43 million, $44 million total investment, $6.5 million in annual margin. We brought that project in service in May 2018.
A lot of the great things about that project is that it's certainly what the margins that are listed there, providing a reasonable return on investment. But we also have about 30,000 dekatherms of additional capacity yet to be sold on that project. And we are looking at delivering additional services to a number of industrial customers over in the Pensacola area.
We've completed another project in New Smyrna Beach, essentially displacing an old Florida gas transmission lateral that we purchased several years ago. This project not only provides great margin for Peninsula pipeline, but it really bolsters the distribution capabilities of our system in and around New Smyrna Beach and allow us for expansion and growth there that we have not been able to do because we have limited pressure and flow capabilities.
And under construction are several projects in our Western Palm Beach service territory. The growth in Western Palm Beach is pretty spectacular. At this point, there are some large city-sized developments going in, in Western Palm Beach. And we are expanding our Peninsula Pipeline capabilities to deliver gas off of both Gulfstream and Florida Gas Transmission interstate pipeline systems to serve the developments.
We're listing about a $30 million total capital investment, that's Peninsula Pipeline investment level. What's not shown here are the distribution system investments that will follow as we take gas to the residences and businesses in this area. We're anticipating at least additional $10 million in distribution investment over the next few years in Western Palm Beach.
One of the things on Slide 24 that I'm really very bullish about is our acquisition of Marlin Gas Services, a compressed natural gas transport business. We have been looking at this business for a number of years hoping to acquire it. And finally, we're able to work the deal out with the principal owner. We are -- in our Florida Public Utilities and Central Florida gas operating areas, we're large customers of Marlin.
We believe that the services that this company provides will be in significant demand for many years to come, not only on an emergency services basis but providing temporary services for companies that are doing scheduled maintenance. And we are finding a number of other opportunities to provide services for Marlin. We use them in our distribution systems to hold distribution systems before we can get a pipeline extended out and make a permanent interconnection into our system.
We did that for several months with our expansion on -- in Fernandina Beach on Amelia Island. We currently, I believe, have about 8 of the Marlin tube couriers that you see in the picture on Slide 24, scattered about our distribution systems, especially in Western Palm Beach, holding subdivisions until we can get the pipeline there.
Now we're also finding additional market opportunities for this business in transporting, for example, biogas from landfills into distribution facilities or pipeline facilities for other customers.
So I think there are great growth opportunities for Marlin. I believe the $4.5 million in margin that we've listed here in 2019 is actually going to be significantly low compared to what we achieve by the end of the year.
Sharp Energy on Slide 25 continues to grow through acquisitions. We mentioned the Ohl acquisition up in the Poconos, adding 2,500 customers. That is -- has been fairly easily integrated into Sharp's existing operations in that area.
We're also seeing significant expansion of our AutoGas business, which is leading us into areas that allow us to expand our retail services into Virginia and into other areas around the Peninsula here at Delmarva.
Turning to Slide 26. One of the things that makes all this possible, we believe, and I mentioned this earlier, is the very strong culture that looks at sustained growth. We have great employees in this company, and they're always bringing ideas and are always bringing creative thinking to the table on how we can grow the business. And I think it really is one of the things that characterizes our company and differentiates us from most of the other regulated utilities, certainly, that I've been a part of over the years. And we'll work very hard to continue to sustain that company -- that culture and promote it.
Just a couple of final thoughts on our capital spending forecast on Slide 27. I think Beth has wandered around talking about spending $1 billion -- investing $1 billion over the next 5 years, starting in 2018. We're, obviously, on a pretty good run to do that with a record year of $293 million in 2018. We originally offered an investment band that range from $600 million on the low end to about $1 billion through 2022. And we've recently adjusted that low end of the band up to $750 million. We feel very comfortable in that forecast. I believe it probably will hit $1 billion, but the $750 million, I think, is a number that we're comfortable with. And so you can see us providing some guidance here on our capital over the next few years.
And the same thing is true on Slide 28 with our earnings per share outlook. We had originally provided a band ranging from 7.75% to 9.5%. And I think that, that is still something that we would hold to be accurate at this point. We're certainly going to revisit that projected band once we complete the regulatory actions related to the TCJA tax dispositions, but again, I think, we will be in that general band.
And as Beth mentioned earlier, we're working to maintain our target equity to total capitalization ratio in that 50% to 60% range, our dividend payout ratio in the 45% range and our dividend share growth certainly has been supportive. And we continue to believe that will be supported by earnings per share growth.
Turning to Slide 29. Total shareholder return, seeing this comparison to Broader Market -- S&P 500 Companies and our peer group several times in our earnings reports in the past. I think the obvious point here is that we have continued to exceed peer group. We're continuing to show up in the 75 -- 75th percentile for all periods shown. And it's one of the key objectives that we have in the company is to maintain this level of earnings performance.
So at the end of the day, my goal, and I think the goal of our entire team, is to be sitting here 10 years from now, having continued to generate the same level of performance that you've seen out of us over the past 10 years.
I'm excited about the enthusiasm and the drive that I see throughout the company in all of our operating areas. I know that our employees can accomplish great things; we've already done that. I know that we will continue to do that.
So thank you very much for joining us today. And we will take any questions that you may have.
