A group of sustainable energy advocates have partnered with two of Oregon’s largest power companies to try to reduce coal consumption in the state.  The coalition of environmental groups has agreed to drop its bid to force power companies to offer 50 percent renewable energy by 2040, but instead will ask the Legislature to pass a similar proposal.  The coalition has reached an agreement with Pacific Power and Portland General Electric to draft a proposal that will debut next week when the House Committee on Energy and Environment meets.  Citizens Utility Board of Oregon executive director Bob Jenks says the plan keeps a four percent cost cap on any new power generated from renewables, and outlines an orderly transition to cleaner power.  The proposal would grant the utility companies flexibility in how they use renewable-energy credits, the ability to build electric charging stations into rates, and the ability to block an entity from acquiring service territory without consent.
