Virginia SB 250 was approved on April 22, 2026 as Acts of Assembly Chapter 998, and its portable-solar provisions take effect January 1, 2027, codified at Va. Code 56-596.8 and 55.1-1212.1. Qualifying small portable solar generation devices, up to 1,200 watts per customer or per residential building unit in multi-family housing, are exempt from interconnection requirements, net metering and utility approval, and utilities may not charge related fees or require extra equipment, though a utility may install an automatic locking disconnect switch where a property has more than one device or the circuit requires it. The customer must submit the form established by the Commission, online or by mail, before installation, and the utility has 15 days to respond. The act also has the Secretary of Commerce and Trade convene a work group on safety standards, reporting by November 15, 2026.
Statutory cap (effective January 1, 2027): 1200W (Per customer, or per residential building unit in multi-family housing. Output to the receptacle outlet of 391 W or less is exempt from product-listing provisions that would require premises, wiring or panel alterations). Note: this statute takes effect on January 1, 2027; prior to that date, standard interconnection rules apply. No utility approval, fee or extra equipment, though the utility may install an automatic locking disconnect switch where a property has more than one device or the circuit requires it; customer submits the form established by the Commission before installation and the utility has 15 days to respond; does not apply to rental units billed under a ratio utility billing system
