Thanks, Ben. Good morning, everyone, and thank you for joining us today.
As you can see on Slide 3, our second quarter was highlighted by a solid portfolio performance and a successful startup at the Lancaster Plant, which is currently running at capacity. WES increased its distribution to $0.65 per unit in the second quarter, its 21st consecutive quarterly increase. This is a 16% increase over last year. WGP increased its distribution to $0.27125 per unit, which is a 37% increase over last year.
Yesterday, we reported adjusted EBITDA of $167 million and distributable cash flow of $137 million, both of which are in line with our expectations. Our resulting coverage ratio of 1.3x was comfortably above our long-term target of 1.1x.
Our second quarter natural gas throughput was marked by sequential growth in the DJ, Marcellus and Green River basins. We also experienced throughput growth at all of our crude and NGL assets.
Our adjusted gross margin for natural gas assets increased by $0.05 per Mcf to $0.65 per Mcf, primarily driven by higher margins at the DJ Basin complex. Our adjusted gross margin for crude and NGL assets increased by $0.54 per barrel to $2.06 per barrel, primarily driven by the receipt of our first distributions from Front Range pipeline.
With respect to the second train at our Lancaster facility, I'm pleased to report that we remain on schedule for our second quarter 2015 in-service date. Approximately 25% of pipe welding is now complete. The rest of the compressors arrived at the site in late July, and we expect to demethanize the tower to arrive this month.
I'm also pleased to announce that we've recently signed an agreement with a third-party producer that enables us to expand our Hilight facility by $20 million a day. The Hilight facility, which we acquired in 2008, is located in Eastern Wyoming and benefits from the increased recent drilling activity in the Powder River basin.
As you read in yesterday's release, we're raising our total capital expenditure guidance to $720 million to $770 million. This includes additional capital required primarily at the DJ Basin complex, the Hilight facility, the Front Range pipeline and at our Haley Gathering System, which we are currently repurchasing to be able to handle rich gas from Anadarko's West Texas production. Our full year guidance for all other metrics is currently unchanged.
As it is our custom during our second quarter earnings call, I'd like to take a moment to reflect on how far we've come since WES' IPO in 2008. WES recently celebrated its sixth birthday and during this period, the enterprise has more than quadrupled, the quarterly distribution has more than doubled, and we have completed over $3 billion of acquisitions and have been invested over $2 billion in organic capital projects. We remain extremely grateful to our unitholders and lenders for your support over the years, and we look forward to continue our relationship for years to come.
With that, operator, I'd like to open up the line for questions.
