Who it is for
Residents in these 17 rural Northern California counties:
Alpine, Amador, Butte, Calaveras, El Dorado, Humboldt, Lake, Lassen, Mariposa, Mendocino, Nevada, Placer, Plumas, Sierra, Sutter, Tuolumne, Yuba.
You must also be a customer of one of: PG&E, Pioneer Community Energy, Sonoma Clean Power, or Redwood Coast Energy Authority.
Nevada County (Grass Valley) residents on PG&E or Pioneer qualify.
What you actually get
- Free home energy assessment — a walkthrough of your home to identify where you're losing energy and what upgrades would help most.
- Free energy efficiency kit — a starter pack of low-cost items (LEDs, weatherstripping, etc.) you can install yourself.
- Rebates for upgrades to energy-efficient electric appliances, heating and cooling equipment, and insulation. Exact rebate amounts depend on the upgrade and your utility — use the rebate finder on the site for current numbers.
How to start
- Go to northernren.org/residential and use the rebate finder. You'll enter your utility account info to see what you qualify for.
- For the free assessment or kit, contact NREN directly: info@northernREN.org, or use the form at northernren.org/contact.
- No phone number is published — email is the main contact channel.
Worth knowing
- The website lists business, public-sector, workforce, and financing programs as "Coming Soon" — residential is the live track right now.
- Rebates stack with utility programs (PG&E Energy Savings Assistance, TECH Clean California) but rules vary. Ask in your intake email if you're stacking.
- If you rent, ask your landlord before scheduling the assessment — some upgrades need owner approval.
