Travis Hoium (TMFFlushDraw) Mar 4, 2018 at 2:02PM Energy storage is finally becoming a legitimate option for utilities, commercial-building owners, and homeowners across the country. The biggest opportunity in 2018 may be in the commercial market, where the combination of solar and storage can create a cost-savings combo that gives building operators a lot of flexibility to control their energy costs. Commercial solar projects alone have always struggled to be justifiable financially, because commercial customers' bills typically include a payment for the energy they consume (consumption charge) and another portion based on their peak demand (demand charge). Traditional solar net metering may only reduce half of a customer's bill, but combining solar with energy storage can reduce the cost of both components on utility bills and makes a valuable combo for the renewable-energy industry. Solar and Energy Storage Go Corporate Now things are taking off. The combination of renewables and storage, as the Tesla battery in South Australia has demonstrated, are natural partners.
