San Antonio-based CPS Energy is working on a project that, if successful, will help solve one of its trickiest problems in solar and wind energy production.
The public utility won a $3 million grant from the Texas Commission on Environmental Quality to develop a commercial battery to store large amounts of solar and wind power during peak production, which generally isn’t when people need it the most.
Renewable energy production can be fickle and unpredictable since it relies on the weather. Peak usage in Texas, on the other hand, is almost always in the evenings when people get home and turn on the air conditioning. The trouble with using wind and solar energy is shifting the power produced during the day and at night to peak usage times.
