Minnesota’s rural distributed generation customers won a major victory this week when state regulators halted the practice by cooperatives of applying fixed charges for solar installations. Regulators ruled June 9 that cooperatives must file requests for small power production tariffs with the Minnesota Public Utilities Commission, which makes the final determination on those fees. The commission ruled those fees must now be suspended until an investigation is completed. Rural cooperatives lost their argument that the PUC had no jurisdiction in the matter of fixed charges for solar customers. Co-ops believed their boards would be the final arbiters of those charges.
