Partners Group, the global private markets investment manager, acting on behalf of its clients, and OPTrust, a Canadian pension fund, have agreed to acquire a 50% joint control stake in Superior Pipeline Company (“Superior” or “the Company”), a leading midstream energy infrastructure company in the US. The stake is being acquired from US energy firm Unit Corporation (“Unit”, NYSE: UNT), which will continue to hold the remainder of the equity, in a transaction that values Superior at USD 600 million.

Founded in 1996 and based in Tulsa, Oklahoma, Superior is a full-service midstream energy company providing services to producers for gas gathering, processing, treating, compression, dehydration, transportation and marketing of natural gas and natural gas liquids. Today, the Company owns and operates three natural gas treatment plants, 13 processing plants, 22 active gathering systems, and approximately 1,455 miles of pipeline across the US. The majority of its revenues are generated from long-term, fixed-fee contracts.

Following the investment, Partners Group and OPTrust, together with Unit, will work closely with Superior’s management team, led by Bob Parks, to grow its existing gathering systems and processing plants organically and to identify attractive acquisition targets to expand the platform.

Bob Parks, Founder and President of Superior, comments: “We are excited to welcome Partners Group and OPTrust on board and look forward to leveraging their proven track records of investment in the infrastructure sector. At Superior, we are committed to being the best midstream provider in the industry and are convinced our new partners share the entrepreneurial mindset that will allow us to achieve this goal.”

Todd Bright, Partner, Head of Private Infrastructure Americas, Partners Group, states: “We see compelling relative value in the US midstream segment, which is benefiting from the ongoing shale revolution. The US has become a net exporter of natural gas for the first time in 60 years, and there is a fundamental need for infrastructure that facilitates the delivery of that gas to end users. Superior is a proven provider of that infrastructure.”

Gavin Ingram, Global Head of Infrastructure, OPTrust, adds: “OPTrust is very pleased to be partnered with Unit and Partners Group in Superior. Superior’s strong management team, diversified asset base and attractive growth prospects make it an exciting investment opportunity. Superior is an excellent strategic fit within our existing portfolio of midstream investments, and we look forward to capitalizing on the growth opportunities ahead of us.”

Superior is the latest addition to Partners Group’s substantial portfolio of North American natural gas infrastructure assets. The firm’s most recent transactions include its investment in the construction of the Raven project, an ethylene to butene-1 processing facility to be located in Baytown, Texas, and the USD 240 million private placement of 10.75% Class A Convertible Preferred Units of NGL Energy Partners LP (NYSE: NGL), a diversified midstream energy company. In 2015, Partners Group acquired a joint control stake in Sentinel Energy Center, an 800 MW California-based natural gas-fired power generation facility, while in 2014, it acquired a majority stake in Fermaca, a leading provider of long-haul natural gas transportation infrastructure in Mexico and the US.

Partners Group, the global private markets investment manager, has sold its stake in Japan Solar, a 610MW platform of Japanese solar power assets, on behalf of its clients. The stake was sold to a consortium led by Global Infrastructure Partners (“GIP”), generating a blended gross return of 3.2x on the original investment for Partners Group’s programs.

Partners Group invested alongside Equis Group to acquire its initial stake in Japan Solar in 2013, shortly after the Japanese government introduced a Feed-in Tariff to encourage investment in the renewable energy sector. Partners Group and others invested an initial USD 250 million to fund the construction of utility-scale power plants across the country. Japan Solar partnered with Nippon Renewable Energy, today one of Japan’s largest independent solar utility businesses, to support the build-out of the platform. Partners Group made a further equity investment into Japan Solar during the holding period, making it the largest shareholder in the platform.

At the time the sale to GIP was agreed, Japan Solar consisted of 27 secured projects totaling more than 610MW of capacity, of which over 200MW was operational and contracted into long-term power purchase agreements with Japanese electric utility companies. It is estimated that once Japan Solar’s secured projects become operational, they will generate enough energy to power around 133,000 households.

Benjamin Haan, Partner, Head of Private Infrastructure Asia, Partners Group, comments: “Japan Solar was a timely project and we are delighted to have contributed to the build-out of Japan’s renewable energy production capacity. The successful sale of our stake in Japan Solar ahead of our original exit timeline provides an attractive return to our clients and endorses our strategy of platform-building in markets supported by transformative trends.”

The sale of its holding in Japan Solar is Partners Group’s third announced infrastructure exit this month on behalf of its clients. Earlier in January, Partners Group announced it had agreed to sell its ownership stake in Silicon Ranch Corporation, a leading developer, owner and operator of solar energy facilities in the US, to Shell. The firm also sold its ownership stake in the Victorian Comprehensive Cancer Centre, a cancer research, treatment and education centre in Melbourne, Australia, to AMP Capital’s Community Infrastructure Fund.

Partners Group, the global private markets investment manager, has, on behalf of its clients, agreed to sell its 43.83% ownership stake in Silicon Ranch Corporation (“Silicon Ranch” or “the Company”), a leading developer, owner and operator of solar energy facilities in the US. Partners Group is selling its equity stake to Shell for minimum proceeds of USD 193 million and up to USD 217 million, dependent on the Company achieving predetermined milestones. In addition, Partners Group will continue to support Silicon Ranch through a newly issued junior debt financing simultaneous with the closing of the sale.

Founded in 2011 and headquartered in Nashville, Tennessee, Silicon Ranch is one of the fastest-growing, independent solar power producers in the US. Since Partners Group’s investment into Silicon Ranch in April 2016, the Company has quadrupled its operating portfolio of commercial- and utility-scale solar projects. It now has approximately 880MW of contracted, under construction, or operating solar PV systems across 14 US states, as well as close to 1GW of additional development pipeline. As the Company’s largest shareholder, Partners Group worked closely with the management team and other shareholders during a period of rapid growth.

Todd Bright, Partner, Head of Private Infrastructure Americas, Partners Group, states: “We are immensely proud of having supported Silicon Ranch in its recent expansion. With our support, the Company has been able to execute its growth plan faster than expected and we are taking the opportunity to divest our equity stake to a strategic investor ahead of the original investment plan. Nonetheless, we remain convinced of Silicon Ranch’s growth potential, as well as of the appetite for solar energy in the US, and are pleased to be able to continue to support the Company as an investor on behalf of our clients.”

Partners Group is a significant investor in renewable energy projects worldwide on behalf of its clients, with a particular focus on solar and wind energy. In addition to the continued support of Silicon Ranch, Partners Group recently announced the acquisition of a 45% equity stake in Borssele III/IV, a 731.5MW construction-ready offshore wind farm in the Netherlands
