A California developer believes grid-connected batteries represent the next step in advancing electric efficiency standards on its development portfolio.
The Irvine Co. and Advanced Microgrid Solutions recently installed 16 Tesla PowerPack battery systems at an office tower. It was the first installation in what will be a fleet of Irvine Co. Hybrid-Electric Buildings that will be used for grid support by Southern California Edison.
The hybrid-electric building, as an Irvine executive calls it, charges its battery system on off-peak hours and later discharges the battery during times of peak energy use. This reduces the energy drawn from the electricity grid during peak periods.
The result is lower electricity costs (10% savings or more) and a more stable and flexible electric grid. With large users drawing power from batteries during peak times, utilities can avoid starting additional power plants to serve peak loads, thereby reducing associated greenhouse-gas emissions.
Battery storage can also be combined with photovoltaic panels, providing additional cost savings and environmental benefits.
