Why batteries pay differently here
San Isabel’s one-to-one crediting means an exported kilowatt-hour is already worth as much as one you use, so storing solar for the evening adds little bill value. Black Hills customers should check their current rate schedule; unless you’re on a time-varying rate, a battery’s value is mostly backup.
That’s an honest reason not to buy one purely for savings. If outages are rare on your street and nobody in the house depends on powered medical equipment, solar alone may be the better buy.
Where backup matters
Rural San Isabel members near Rye and on long lines out east see more weather outages than city customers. Wells, livestock water tanks and medical equipment are the loads that make a battery worth it. A Powerwall 3 (about $19,000 installed) or a 9 kWh SigEnergy starter system ($15,500, expandable in $3,500 steps) covers most essential-load plans.
Incentives in 2026
Black Hills has offered a modest battery incentive under its 2023–2026 plan; confirm it’s still available. Statewide, Colorado’s 10% battery tax credit runs through tax year 2026, and batteries are exempt from state sales tax.
