Research into how Minnesota could reach a 2050 solar penetration target of 70 % has argued that overbuilding solar projects and accepting utility curtailment would be ‘ considerably ’ cheaper than adding energy storage . The study argues that the falling costs of solar projects allow additional capacity to be added at less cost than co - locating utilities to make use of any surplus generation . However , the Minnesota Solar Energy Industry Association has pushed back , claiming such a move would make financing solar projects difficult .
Research into how Minnesota could reach a 2050 renewables penetration target of 70% has argued that overbuilding solar projects and accepting utility curtailment would be ‘considerably’ cheaper than adding energy storage. The study argues that the falling costs of solar would allow additional capacity to be added at less cost than co-locating batteries to make use of any surplus generation. However, the Minnesota Solar Energy Industries Association has pushed back, claiming such a strategy would make financing solar projects difficult.
