Daily Energy Insider | Kim Riley, July 8
Toward improving system reliability, the Minnesota Public Utilities Commission (PUC) July 1 approved two renewable energy projects that together will add more than 475 megawatts (MW) of solar energy capacity to the state’s grid.
“These approvals represent a significant step forward in Minnesota’s clean energy transition,” said PUC Chair Katie Sieben. “These projects also bring important economic opportunities to the rural communities that host them.”
“By expanding our renewable energy portfolio and integrating vital battery storage, we are enhancing the stability and resilience of our electric grid while helping to meet the state’s ambitious energy and climate goals,” Sieben said.
The Iron Pine Solar Project received a site permit for a 325-MW solar energy facility in Pine County, Minn., along with a route permit for a one-mile, 230-kilovolt (kV) generation tie-line that will connect the project to the grid, according to the PUC.
The project represents one of the largest single-site solar installations approved in the state and will play a key role in delivering low-cost, clean power to Minnesota’s electric system, the commission added.
The Northern Crescent Solar Project includes up to 150 MW of alternating current (MWac) solar generation and a 50-MWac battery energy storage system that will be housed in a 3.2-acre facility using lithium iron phosphate battery technology.
The project will interconnect to the grid via a short 300-feet, 161-kV transmission line to an existing Xcel Energy substation, the commission said, adding that a final interconnection agreement is expected from the Midcontinent Independent System Operator in the second half of the year.
The PUC said that both projects underwent comprehensive environmental reviews and robust public engagement processes to ensure the inclusion of community input and environmental considerations.
