If you’re looking for big trends to watch in electricity markets, there’s no shortage these days. Some are broad policy issues, like the growing number of states targeting 100% clean grids (definitions vary but they are all directionally similar). Others are being driven by technology innovation, such as the continuing price declines for renewable energy and batteries. Some have a strong consumer focus, like smart thermostats and electric vehicles. Others are downright wonky, like the ongoing challenges related to the participation of distributed energy resources (DERs) in organized wholesale markets, or how states are trying to modernize the utility business model for the 21st century. One that we’ll look at today is how state policies to achieve 100% clean grids affect resource adequacy – that is, ensuring there is sufficient generating capacity to meet demand at all times.
