Fossil fuel power plants are quickly becoming uneconomical compared to cheaper clean energy generation. More than 15 gigawatts (GW) of U.S. coal-fired power capacity is expected to close in 2018, and at least 36 GW of coal-fired capacity is forecast to be retired by 2024.
Regulators, utilities, and investors must work together to ensure customers benefit from closures while helping affected communities transition away from a coal-based economy.
This series of policy briefs highlights different tools to balance stakeholder interests, facilitate the transition away from uneconomic fossil fuel, provide utility stakeholders with tools to manage financial transition and balance stakeholder interests, and help states embrace clean energy.
By analyzing publicly available financial information, policymakers and utility stakeholders can identify where running existing fossil fuel generation costs more than replacing it with new wind or solar. A suite of financial instruments can facilitate and reduce costs of this financial transition away from fossil fuels toward clean energy.
This brief uses Colorado’s experience transitioning from coal to clean energy as a case study analyzing existing generation costs, and introduces financial tools to help electric utilities that own fossil generation manage the clean energy transition.
Early retirement of uneconomic coal assets can improve shareholder earnings if a utility is allowed to reinvest capital in new renewable energy generation. When building new renewables is cheaper than operating existing coal, swapping steel for fuel adds value for investors, customers, and the environment.
This brief addresses equity shareholder perspectives and suggests how potential funding sources can mitigate impacts on communities and workers affected by early plant retirements while improving environmental performance.
Depreciation accounting recognizes asset value reduction over time. For coal plants, depreciation determines the value remaining when plants retire early. Depreciation is an important tool for transitioning away from older assets, such as coal plants, to cheaper resources, such as wind and solar.
This brief reviews how depreciation schedules affect utility earnings and ratepayer costs, as well as other stakeholder interests.
When electric utilities transition from fossil fuels to clean energy, they must address unrecovered investment balances. Depreciation schedules are often accelerated to line up with earlier-than-planned retirement dates, which can increase short term consumer rates.
This brief reviews how utilities can refinance undepreciated balances on plants in service to lessen the consumer rate burden, primarily through replacing some portion of equity with corporate debt.
