The U.S. Court of Appeals for the D.C. Circuit on Jan. 19 vacated the Environmental Protection Agency’s Affordable Clean Energy, or ACE, rule for regulating power plant emissions, finding that the rule “hinged on a fundamental misconstruction” of the Clean Air Act. The agency finalized the rule in June 2019 replacing more stringent Obama-era restrictions…....
The Washington State Department of Commerce and the Utilities and Transportation Commission on Jan 5 adopted rules for the implementation of the 2019 Clean Energy Transformation Act. The law requires the state’s electricity supply to be carbon-neutral by 2030 and carbon-free by 2045, and directs electric utilities to phase out coal from their generation portfolio…...
The Regional Greenhouse Gas Initiative (RGGI), which established the nation's first mandatory emissions-trading program, received a further boost as Virginia finalized regulations to become its eleventh member and Pennsylvania, the third largest coal-producing state, adopted draft regulations to join the program, following New Jersey’s re-entry after a decade.
In 2019, the weighted average wholesale price of solar PV-generated electricity was $83 per megawatthour, more than double the price of wind, fossil fuels, or nuclear, according to an Oct. 9 report from the U.S. Energy Information Administration. The higher price is partly driven by geography and timing. Wholesale electricity prices rise when demand within…...
The U.S. Environmental Protection Agency on Oct. 1 finalized a rule allowing a major source of hazardous air pollutants to reclassify as an “area source,” a less stringent category under the Clean Air Act, any time it implements measures to limit emissions. The action implements the agency’s 2018 guidance that withdrew the 1995 “Once In,…...
State policy goals are driving comprehensive grid modernization endeavors aimed at transitioning to a flexible and efficient grid that caters to the needs of the evolving electric sector and diverse customer interests. A growing number of state regulators and utilities alike are embarking on innovative ventures, striving towards necessary enhancements to accomplish energy and environmental goals.
The share of U.S. energy production from fossil fuels peaked in 1966 at 93 percent, but production from nuclear power and renewables have also risen. Fossil fuels have accounted for about 80 percent of U.S. energy production in the past decade, according to a Sept. 14 report from the U.S. Energy Information Administration. In 2019,…...
The Pennsylvania Environmental Quality Board on Sept. 15 voted in favor of a proposed regulation that would allow the state to participate in the Regional Greenhouse Gas Initiative, or RGGI, a cooperative effort among 10 states to cap and reduce emissions from the power sector. Democratic Governor Tom Wolf applauded the move, which stems from…...
The Pennsylvania Senate on Sept. 9 voted in favor of a bill that would require legislative approval before the state can impose a carbon tax or join a multi-state carbon-trading program. The House of Representatives approved the legislation in July. The move comes ahead of a Sept. 15 meeting of the state’s Environmental Quality Board…
Proposals to accelerate the phase-out of coal-fired generation appear more prominently in long-term resource plans of U.S. electric utilities, reflecting the growing shift to renewable energy. The transition from coal continues to be driven by state clean energy mandates, emissions reduction goals, low natural gas prices, and increased availability of low-cost renewables and storage resources.
Duke Energy Carolinas LLC and Duke Energy Progress LLC on Sept. 1 unveiled their 15-year integrated resource plans for the Carolinas, presenting a range of scenarios with accelerated coal retirement options and substantial increases in solar, wind, and energy storage technologies. The proposal details six generation portfolios that would keep Duke Energy Corp. on a…...
From 2011 to 2019, the U.S. repurposed 121 coal-fired plants to burn other fuels, of which 103 switched to natural gas, according to an Aug. 5 report from the U.S. Energy Information Administration. The agency attributed the trend to stricter emission standards, low gas prices, and more efficient natural gas turbine technology. Of the 316.8-gigawatts…...
