Senate passes energy bill with balcony solar

Massachusetts took a step toward plug-in solar on July 1, 2026, when the state Senate folded balcony solar into a sweeping energy-affordability bill. The package is estimated to save ratepayers billions over a decade while making it easier to generate power at home.

The catch: the Senate's version still needs to be reconciled with the House before anything becomes law. Massachusetts is a step behind states that have already cleared both chambers, but the momentum is real.

Why it's part of a bigger bill

Rather than a standalone measure, plug-in solar rode in on a broad affordability package aimed at lowering utility bills. That can help it pass — but it also means the balcony-solar language could still be amended in negotiations with the House.

What to watch

• House action on the Senate's energy affordability bill.
• Whether the plug-in solar provisions survive conference intact.
• A final wattage cap and any certification requirements.
