Fifteen years ago, experts debated whether power grids could cope with more than 15%-20% renewables, given their intermittency. That ratio has been comfortably pushed to 40% or more in places as diverse as Denmark, South Australia and California. Solutions to the intermittency issue are well known and increasingly being implemented. Attention is now turning to how much nuclear and controllable renewables — such as hydropower — should be retained for power systems to economically reach full decarbonization.

Power grids are coping with rising volumes of intermittent renewables through storage, interconnection, demand management and other approaches.
