Ameresco announces partnership with Juneau Hydropower for hydroelectric facility

Ameresco (AMRC) announced its partnership with Juneau Hydropower, a recently licensed utility to develop, construct and operate a 19.8 megawatt hydroelectric facility at Sweetheart Lake, 33 miles south of downtown Juneau and its transmission and distribution assets. The Sweetheart Lake Hydroelectric Facility is designed to generate an average of 116,000 megawatt-hours annually, providing a 20% increase in baseload clean hydropower over Juneau’s current electrical generation. The project scope also covers the installation of a battery energy storage system, over 40 miles of high-voltage transmission infrastructure, including eight miles of undersea cable that will cross Gilbert Bay, and an interconnection substation with the existing Snettisham Transmission line adding energy security to Alaska’s capital city.
