Renewable energy generation is intermittent in its power distribution to grid operators (which can incur charges), unlike conventional base-load power. Integrated battery storage units enable renewables project owners and operators to smooth power output and time-shift output delivery to take advantage of better priced periods in the market.
“All these renewables projects coming online are not good for grid stability,” says Oliver Irwin, a partner at law firm Bracewell. “But battery storage systems enable host governments to start looking at renewable energy like base-load power. For emergency responses to grid outages, batteries can react in milliseconds, whereas it takes time to fire up a gas-fired plant.”
