Duke Energy and energy storage company Xtreme Power announced the commencement of operations at the Notrees energy storage unit in West Texas.

The integrated facility at Notrees provides both environmentally friendly and flexible capacity to the Electric Reliability Council Of Texas (ERCOT), which operates the electrical grid in Texas and manages 75 percent of the deregulated market in the state.

The energy storage system is part of Duke Energy's Notrees 153 MW wind power project. The 36 MW battery storage system is capable of deploying fast-acting reserves to support ERCOT grid reliability and helping the System Operator maintain supply and demand balance with near-instantaneous feedback of frequency changes or other unexpected events.

In addition to other energy management services, the storage unit supports ultimate wind farm performance as it can absorb power from the wind farm during times of low demand or high curtailment and release power when it is most beneficial to the market.

Xtreme Power's control system, XACT, will manage real-time performance and response of the system in response to site and grid conditions.

This project marks the eighth energy storage project installed by Xtreme Power over the past year. Xtreme Power serves more than eleven customers and remotely monitors more than 250,000 hours of operations.
