SC |agenda How batteries could change our energy future Businesses around the world are betting big on batter- ies for electric cars, and in a roundabout way, this trend could change how electricity is delivered to your home. Over the past eight years, global battery production ca- pacity has grown eight times to supply the expanding mar- ket for electric vehicles. New manufacturing plants under construction in the United States, Europe and Asia could increase capacity another fifive times in the next eight years. As battery production in- creases, consumers can expect improved performance and lower prices, says Jan Ahlen, the director of energy solutions for the National Rural Electric Cooperative Association (NRECA). The benefifit for home electricity consumers is that these better and cheaper batteries can be connected to make large “utility-scale” batteries with multiple appli- cations. Here are three ways batteries could change the future of electricity. Timing for the best price: The cost of the electricity This 13-megawatt Tesla solar field, which is coupled with a 52-megawatt-hour battery storage system, is owned by Kaua’i Island Utility Co-op and allows the cooperative to store solar power during the day and dispatch it over a four-hour period during the evening when energy demand is high. varies with seasons and even the time of day as demand for electricity flfluctuates. If your cooperative can buy electricity and store it in a battery when the price is lowest, then draw from the battery when market prices are highest, members may benefifit from lower rates. Helping renewable energy: There’s no solar power at night or wind energy in calm weather. Utility-scale batter- ies could change that, storing electricity during peak pro- duction, and making it avail- able when needed. Outage management: Utility-scale batteries are an important part of microgrids, a new concept for handling widespread power outages. Microgrids use independent power sources, like batteries, to keep electricity flflowing to high- priority facilities like hospitals, storm shelters and gas stations until service can be restored for the entire community. “Batteries are becoming better, faster and cheaper,” says Ahlen. He adds that they are a trend that’s “opening up many new opportunities for GONE FISHIN’ utilities to help provide more affordable and reliable power for their consumers.” PAUL WESSLUND writes on con- sumer and cooperative affairs for the National Rural Electric Cooperative Association, the national trade association rep- resenting more than 900 local electric cooperatives.
