Indiana Supreme Court Approves CenterPoint’s Solar Energy Billing Process

EVANSVILLE — The Indiana Supreme Court has ruled that CenterPoint Energy can bill customers for solar panels as originally requested in 2020, meaning customers are likely to receive reduced credits for the energy they produce.

The court agreed with a decision by the Indiana Utility Regulatory Commission, not the reversal ordered by the Indiana Court of Appeals in February 2022. The Court of Appeals had ruled in favor of consumer groups, who said the change would fall short of the total savings for customers using solar.

The Court of Appeals ruled that state law SEA 309 requires billing to be calculated as the difference between energy consumed and energy returned to the grid. The Indiana Supreme Court justices disagreed, saying that CenterPoint’s proposed “instant” netting method did not violate state law.
