District of Columbia (Washington, DC) SREC Market Guide: DC RPS Solar Carve-Out (PJM-GATS Tier 1 Solar REC)
Why Washington, DC is the single most lucrative residential SREC cash market in the world: how the $460/MWh Alternative Compliance Payment (ACP) forces Pepco suppliers to pay DC homeowners $395–$440 for every 1,000 kWh of solar generated—paying back an entire 10kW rooftop system in just 2.8 years!
1. How the District of Columbia (Washington, DC) SREC Market & Registration Process Works
Mechanic 1 — How DC’s 10%–15% Local Solar Carve-Out & $460/MWh ACP Penalty Create a Cash Mint: Under the CleanEnergy DC Omnibus Amendment Act, electricity suppliers serving Washington, DC must source a rapidly rising percentage of all District electricity strictly from solar arrays physically located inside DC boundaries (or legacy grandfathered feeders). If a utility supplier fails to buy enough DC SRECs, it must pay a statutory fine (Alternative Compliance Payment — ACP) of $460/MWh in 2026 ($440/MWh through 2028)—locking in spot SREC prices between $395 and $440!
Mechanic 2 — Exact 10kW DC Rowhouse / Single-Family Cash Math ($4,800+/Year on Top of Pepco Net Metering): A 10 kW DC solar array in Washington, DC (4.4 Peak Sun Hours) generates ~12,200 kWh (12.2 MWh) per year. That mints 12 whole SRECs every 12 months. At $415/SREC, you receive $4,980/year in direct cash checks PLUS ~$2,300/year in Pepco 1:1 full retail net-metering bill savings = $7,280/year total benefit!
Mechanic 3 — Spot Market Brokerage (5% Fee) vs. 3-to-5 Year Fixed Annuity Strip Contracts: When registering your DC system on PJM-GATS through Sol Systems (headquartered right in Washington, DC), SRECTrade, or Flett Exchange, you can either sell each monthly SREC on the spot market at ~$415–$435 (minus a 5%–7% brokerage fee) or lock in a guaranteed multi-year fixed price strip.
Mechanic 4 — Never Sign a DC Solar Lease or PPA That Steals Your $48,000 SREC Stream: Door-to-door solar lease/PPA reps target DC homeowners offering "cheap $0-down solar" while buried in Section 9 of the contract the lease company takes 100% ownership of your DC SRECs! Always buy with cash or a zero-dealer-fee credit union loan in DC so YOU keep 100% of your $46,000–$51,000 10-year SREC cash stream!

District of Columbia (Washington, DC) SREC Trading & Tax FAQ
Can a Maryland or Virginia homeowner sell their solar electricity into the $425/MWh Washington, DC SREC market?
No. In 2011, the DC Council closed the out-of-state boundary loophole (DC Act 19-125). Only solar arrays physically located within the District of Columbia (or connected to a tiny handful of Pepco DC distribution feeders straddling the MD border) qualify for DC Tier 1 SRECs.
Are Washington, DC SREC cash payouts subject to federal income tax?
Generally yes: SREC brokers (Sol Systems, SRECTrade, Flett Exchange) issue an IRS Form 1099-MISC or 1099-NEC for SREC cash proceeds exceeding $600/year. See our IRS Form 5695 & SREC Tax Strategy Guide at /tax for how CPAs report SREC revenue.
How long can a DC residential solar system keep generating and selling SRECs?
In the District of Columbia, a certified solar facility remains eligible to mint and sell DC SRECs for the entire operational life of the system under current DC Public Service Commission rules!
