Regulators were concerned that with the dramatic decline in the cost of renewable energy, maturation of energy storage and rapidly changing customer demand, such a major gas plant investment could become a stranded, uneconomic asset in the future. Regulators are now pushing Vectren to consider more decentralized, lower-carbon resources such as wind, solar and storage that would offer greater resource diversity, flexibility and cost effectiveness.
