IHI Terrasun Completes Commissioning Gemini Solar + Storage Project , one of the largest solar + storage projects in North America
CHICAGO, USA, October, 2024 – IHI Terrasun Solutions has completed commissioning one of the largest renewable energy projects in North America. Gemini Solar + Storage (Gemini) project, located on Bureau of Land Management lands in Clark County, Nevada is operated by IHI Terrasun’s Assured Controls power plant software and will be serviced by the IHI Terrasun Field Engineering team for the next 25 years of operation. With 690MWac of solar capacity and over 1,400MWh of co-located battery energy storage, Gemini will provide clean energy to the Nevada grid at a scale that can replace coal and natural gas electricity generation within one interconnection.
IHI Terrasun’s Assured Controls software will manage all aspects of the co-located facility, including battery energy storage system (BESS): DC-DC converters, inverters, batteries; DC-sided metering, solar generation, trackers, meteorological stations, and capacity banks. It interfaces thousands of pieces of equipment across hundreds of power blocks and miles of network to allow Gemini to operate at peak efficiency. Assured Controls’ solar forecasting technology predicts the solar panels’ energy generation to give the utility visibility into optimal charging and discharging windows.
“Gemini is a remarkable feat that will help guide the future of sustainable energy development,” said Adam Larner of Primergy Solar. “The technical know-how, dedication, expertise of IHI Terrasun undoubtedly helped us see this project through. We look forward to many years of successful operation of the Gemini project.”
“Gemini Solar + Storage is an important clean energy project and an incredible technical achievement that will reap benefits to the Las Vegas area throughout its lifespan,” said Kenshi Suzuki, President of IHI Terrasun. “Our team proved the versatility and resourcefulness of IHI Terrasun, and we are looking forward to the opportunity to work on projects with impact at this scale in the future.”
At its historic size, Gemini can perform grid forming functions as well as shift peak solar generation to times of high demand. It can stabilize the grid when frequency or voltage fluctuations occur. Thanks to this size, Gemini creates an incredibly flexible and reliable renewable energy resource for Nevada electricity grid.
