Utility Xcel Energy’s latest resource plan for Colorado, aimed at increasing renewable energy generation and aiding the retirement of coal plants, was approved by the state’s Public Utilities’ Commission (PUC) on Monday.

Xcel Energy has filed a plan which would retire two coal plants, add significant capacities of renewables and gas – and deploy 275MW specifically in combination with PV.

Median bids received by US utility Xcel Energy in a solicitation for energy resources for energy storage paired with solar came in at US$9 per megawatt lower than the previously observed record.

Energy storage system integrator Younicos has signed off on a deal with Panasonic to design and develop a solar-plus-storage system at Peña Station NEXT in Denver, Colorado, which includes the operations hub for Panasonic Enterprise Solutions Company and Panasonic CityNOW.
