Virginia to rejoin RGGI in July

Virginia plans to return to the Regional Greenhouse Gas Initiative (RGGI) in July, after the state Department of Environmental Quality (DEQ) finalizes new regulations in May, the agency told Argus.

"We plan to rejoin RGGI effective July 1, 2026, and participate in the auctions in September and December," DEQ said.

The agency began the process to return to the northeast US power plant CO2 cap-and-trade program in February after governor Abigail Spanberger (D) a budget bill that directed DEQ to begin work on new regulations.

The agency has until 21 May to finalize new rules to return to RGGI.

"Given the short deadline and specific direction in HB29, we will adopt a final regulation without publishing a draft regulation for comment," DEQ said.

In addition, the agency has been working with RGGI member states to iron out the finer details of Virginia's return to the program, such as its allowance allocation. Calling its discussions with member states "positive", DEQ said that Virginia's allocation "will be consistent with the prior regulation" when the state first joined RGGI in 2021.

Virginia's power plant emissions and allowance allocation were largely even during its participation in RGGI from 2021-23, making its effect on overall fundamentals in the allowance market negligible, according to William Shobe, professor emeritus of public policy at the University of Virginia.

Virginia left RGGI by the end of 2023 at the direction of Spanberger's predecessor, former governor Glenn Youngkin (R), who said the state's participation had led to higher energy costs. Environmental groups sued the Youngkin administration for unilaterally exiting RGGI without approval from the legislature, an argument that a lower court agreed with. Youngkin's administration had been appealing the lower court ruling last year, but attorney general Jay Jones (D), who took office in January, withdrew from the lawsuit earlier in March.

Virginia officials have moved fast to rejoin RGGI since Spanberger — who promised to resume participation in the program during her campaign last year — took office in January. In addition to the budget legislation, state lawmakers also passed two separate bills, HB 397 and SB 802, that require Virginia to rejoin RGGI. Spanberger has until 13 April to sign those bills.

The state has the largest data center market globally, accounting for more than 35pc of the world's hyperscale data centers, according to the Virginia Economic Development Partnership. As a result, it presents a considerable source of demand in the RGGI market, though that demand could be tempered depending on the state's allowance allocation.

Allowance prices have soared in recent weeks since the program's first auction of 2025 cleared high enough to completely drain the year's cost containment reserve (CCR), which held an additional 7.85mn allowances that were released into the market in a bid to mitigate rising prices.

Argus assessed prompt-month and December 2026 allowances at $27.98/short ton (st) and $28.55/st, respectively, on Monday. That assessment is about 53-57pc higher compared with the $18.22/st CCR trigger price for this year.
