Tracking Regional Greenhouse Gas Initiative: When will electricity bills be impacted?
Virginia's return to the Regional Greenhouse Gas Initiative (RGGI) will add a $10 monthly charge to Dominion Energy customers' bills for two years, pending approval. Dominion estimates $1.2B in costs for carbon allowances. Customers will receive credits from auction proceeds, with 45% of funds reducing bills. The first auction yielded $259M, with allowances selling at $37.65. The State Corporation Commission will review the case in October.

What to watch
