Energy > AG Speaking Energy > Federal Clean Energy Initiatives Carry Potential Regulatory and Market Implications
21 Aug '19

In recent weeks, a flurry of Congressional activity has emerged to extend and expand federal support for clean energy initiatives. Introductions of the Renewable Electricity Standard Act1 and Renewable Energy Extension Act2 supplemented a proposed plan3 within the House Committee on Energy and Commerce (“House E&C Committee”) for comprehensive legislation to achieve a 100 percent “clean economy” by 2050. A national renewable electricity standard paired with an extension of the energy investment tax credit, if enacted, would encourage the growth of renewable energy investment and installation. High variable renewable energy (“VRE”) market penetration would necessitate significant changes to existing regulatory structures as well as the operation of wholesale electricity markets across the United States. Such potential changes require consideration and forward planning by industry participants and investors alike.

Renewable Electricity Standard Act

Introduced by Sen. Tom Udall (D-NM) on June 26, the Renewable Electricity Standard Act would amend the Public Utility Regulatory Policies Act of 1978 to establish a national standard intended “to achieve at least 50 percent renewable electricity nationwide” by 2035.4 Beginning in 2020 with a required 1.5 percent increase in renewable electricity generation, the standard would require annual increases in renewable generation by retail electricity providers, ultimately ramping up to 2.5 percent in 2035. Each kilowatt hour of added renewable generation would result in the receipt of a federal renewable energy credit (“REC”) that generators could trade, sell, or bank in order to meet future compliance requirements. Credits would be issued only to eligible generators: those that are not under contract to receive state RECs and are using equipment that “comes online” in 2020 or later, among other “small exceptions.”5 Such requirements could spur new deployment of and investment in renewable generation after 2020. States with existing renewable standards set at or above the federal level are eligible to opt-out of the legislation.6

Renewable Energy Extension Act

On July 25, Rep. Mike Thompson (D-CA), joined by Reps. Paul Cook (R-CA) and Brian Fitzpatrick (R-PA), introduced the Renewable Energy Extension Act.7 Sen. Catherine Cortez Masto (D-NV) introduced companion legislation in the Senate.8 The legislation would amend Section 48 of the Internal Revenue Code9 to extend the expiration date for tax credits across a range of clean energy investments.10 Certain credits, currently set at 30 percent, are scheduled to phase-out this year before expiring in 2021.11 While a 10 percent credit for solar and geothermal energy remains after 2021, this legislation would extend the 30 percent credit for all eligible resources until the end of 2026.12

House E&C Committee Announcement

On July 23, House E&C Committee Chairman, Frank Pallone Jr. (D-NJ), together with Reps. Paul Tonko (N-NY) and Bobby L. Rush (D-IL), announced a new plan to attain a “100 percent clean economy by 2050.”13 Citing a need for greater federal leadership in combatting climate change, Rep. Pallone indicated the Committee’s intention to “produce comprehensive legislation” to meet this target.14 On July 24, the Committee held the first of a number of hearings dedicated to discussing potential policies intended to decarbonize all sectors of the U.S. economy.15 Future hearings will cover the reduction of industrial or transportation emissions, among other topics.16


Despite their limited chance of passage, the legislation, paired with growing public support for clean energy, require industry consideration of potential regulatory changes accommodating greater market penetration of VRE resources.17 One consideration is the effect increased VRE penetration has in reducing wholesale electricity prices—and the challenges such reductions present for the efficient and reliable operation of electricity markets.18

Regulatory battles have already begun with Federal Energy Regulatory Commission (FERC) interventions and rulings on the effect state policies have on the operation of wholesale markets, as we previously reported. More recently, FERC delayed PJM Interconnection, L.L.C’s (PJM) scheduled capacity market auction as it continues to deliberate changes to PJM’s Minimum Offer Price Rule.19 Federal action incentivizing state support for clean energy initiatives, or the implementation of federal standards, could have a significant effect on FERC’s future rulings.
