Natural Gas

Summit’s natural gas experience is very deep. It has developed or co-developed more than 7,800 MW of combined and simple cycle natural gas generation projects. This includes major project development during the last decade in Utah, Washington, Oregon, California, Idaho and Texas. Summit has developed a model for gas project development, contracting and construction that optimizes low cost, risk mitigation for the owner, quality and speed to market. This approach has been very well received by the market, along with Summit’s flexible position relating to project ownership and transaction structure. Summit has been short-listed on two significant natural gas development projects in major utility RFP’s processes since mid-2011. The Summit approach to gas power project development includes a highly customized development team and financing tailored to each project.
