Managing very high renewable penetration is certainly a "complex task" according to Bjarne Brendstrup, senior director in charge of grid development at Denmark's electricity and gas TSO Energinet — but it is not insurmountable. The main issue is flexibility because wind and solar generation depend on weather conditions, which rarely match demand volatility. That can be addressed by a mix of flexibility tools involving demand-side management and various forms of energy storage in batteries, hot water or green gases.
