Developer 8minutenergy Renewables and private asset management firm Capital Dynamics kicked off commercial operation of the 328 MWdc Mount Signal 3 Solar Farm. The project is the largest in the 800 MW Mount Signal solar cluster, which is not only the largest PV project in California, but also among the largest in the world. Mount Signal 3, acquired by Capital Dynamics’ Clean Energy Infrastructure (CEI) business in 2017, commenced construction earlier this year and is being brought to commercial operation ahead of schedule.

8minutenergy was the original developer of all three solar farms in the Mount Signal cluster. With Mount Signal 1 and Mount Signal 3 both now complete, the cluster has approximately 80% of its total final capacity online. Mount Signal 1 and 3 will generate a combined 1.29 billion kilowatt hours (kWh) of clean, renewable power annually for the residents of 15 Southern California counties – enough energy to power over 1 million people during the daytime and reduce carbon emissions by more than 850,000 metric tons each year. Southern California Edison and 8minutenergy signed a long-term power purchase agreement for Mount Signal 3’s energy in 2014.

Mortenson Construction provided the engineering, procurement, and construction (EPC) contracting for the Mount Signal 3 plant. Key suppliers included First Solar with 2.8 million Series 4 thin-film solar panels, NEXTracker with its NX Horizon smart solar tracker, and TMEIC with 96 of their Solar Ware Samurai 2700 Central inverters.

“Mount Signal is a clear demonstration that solar is ready to power California’s 100% clean energy future ahead of schedule,” said Tom Buttgenbach, CEO & President of 8minutenergy. “The Imperial County Board of Supervisors, their staff, our dedicated partners, and the outstanding local workforce were all critical in ensuring that we beat our aggressive timeline in bringing Mount Signal 3 to completion. I’d also like to thank Capital Dynamics and Southern California Edison for being tremendous partners on this project.”

“Capital Dynamics is proud to have the development of Mount Signal 3 completed and now providing hundreds of millions of clean kilowatt hours to the grid. Large-scale solar delivers what California needs, massive amounts of clean energy, reliably, and at a low-cost,” said John Breckenridge, Head of Capital Dynamics’ Clean Energy Infrastructure team. “By completing such a massive PV project ahead of schedule, 8minutenergy has again proven its world-class development and construction management capabilities.”

“We’re proud to be leading the way in supporting the development of clean solar energy on tribal lands,” said Gregory T. Anderson Sr., Chairman of the Moapa Band of Paiutes Tribal Council. “Eagle Shadow Mountain Solar Farm will be special in particular as it’s being built beside a retiring coal plant on our lands, signifying the affordability and importance of renewable energy. We hope to shepherd the way for many other tribes to adopt clean power.”

Eagle Shadow Mountain will be the second solar farm developed on the Moapa River Indian Reservation. The first one was our Project of the Year in 2016. The Moapa Band of Paiutes has become a national clean energy leader and will host in excess of 600 MW of solar on the 72,000-acre reservation. The Eagle Shadow Mountain Solar Farm will be built on non-agricultural land using environmentally sensitive construction.

“We are delighted to be working with 8minutenergy and other top-tier solar developers to bring over one gigawatt of low-cost clean solar power and energy storage to our customers in Nevada,” said Paul Caudill, CEO of NV Energy. “This landmark group of projects will help diversify our state’s electricity generation portfolio at industry-leading costs. We calculate that the direct investment in Nevada’s economy, which includes the cost of construction, will be greater than $2 billion.”

Subject to final approval by the Public Utilities Commission of Nevada, the project will commence construction in mid-2020, and be operational by the end of 2021. Eagle Solar Mountain Solar Farm will have an annual production capacity of over 900 million kilowatt hours (kWh) once complete, enough energy for more than 180,000 homes when producing, and will reduce carbon emissions by more than 600,000 metric tons each year. The project’s development and construction is also expected to create well over 600 jobs in Clark County.
