To re-write the state law regulating electric utility monopolies. The Senate-passed version of the bill is premised on Obama EPA regulations forcing closure of existing coal-fired generating plants and ordering states to re-organize their electric power grid systems. It would essentially replace a market-driven process for new power plant capacity and site decisions with a centralized state process. On its face the bill retains current provisions that allow other power generators to compete with monopoly utilities for a 10 percent slice of the commercial market, but the businesses that buy power this way say the bill's details would end competition. The bill would also increase a mandate that utilities get more power from so-called renewable sources.
