Solutions that change energy consumption patterns, improve efficiency, store energy, improve forecasting of usage patterns, and allow for more flexible operation of power plants are all necessary. The US state of California is exploring options for developing a regional energy grid to help address issues with curtailment of renewable energy supply . The state has already established an Energy Imbalance Market to undertake some small - scale energy trading , which has avoided the need for around 587,000 MWh of curtailment since 2015 . However , curtailment of wind and solar doubled between then and 2017 , wasting enough energy to power most homes . A proposal now before the state legislature would establish a regionalised energy grid which its supporters believe would help control the problem .
