Matrix Renewables Announces the Commissioning of Pleasant Valley Solar 1

LCG, April 15, 2025--Matrix Renewables announced today the successful commissioning of the Pleasant Valley Solar 1 power generation facility in Ada County, Idaho. The 200-MWac solar facility includes a Power Purchase Agreement (PPA) that was secured through negotiation with Meta and Idaho Power. Matrix Renewables states the facility is the largest operational solar facility in Idaho Power's system. Sundt Renewables, the Engineering, Procurement, and Construction (EPC) services provider, completed construction of the project on March 2nd.

Matrix Renewables is a global renewable energy platform backed by TPG Rise and majority owner, and rPlus Energies, development partner and minority owner.

The President and CEO of rPlus Energies stated, "We are proud to see Pleasant Valley Solar come to life. We started developing this project in 2021 and it's especially meaningful for us as Ada County is home to one of our two offices, allowing us to connect with the local community in a deeper way. We look forward to continuing our partnership with Idaho Power and Meta and further contributing to their energy future."

"We are thrilled to celebrate the commissioning of the Pleasant Valley Solar Project," said the Managing Director and Head of U.S. for Matrix Renewables. "This achievement underscores our commitment to expanding renewable energy infrastructure and contributing to local communities. We are grateful for the collaborative efforts of our partners, offtakers, financiers, and the supporting community who made this project possible."

Last November, rPlus Energies announced a long-term PPA with Idaho Power for the 125-MW Pleasant Valley Solar 2 facility in Ada County, Idaho. Both projects will deliver solar energy to Idaho Power's grid and support Meta's goal to operate its nearby data center in Kuna, Idaho with 100 percent renewable energy.
