Increase your home’s resilience with Power+

Through the Inflation Reduction Act (IRA) and the State of Colorado, Energy Storage Systems may now be eligible for up to 40% federal and 10% state tax credits.

  • Power+ installations that are fully paid off within the same year they’re installed may now be eligible for these tax credits.
  • Members who take advantage of the 10 years of payments at 0% interest are not eligible for these tax credits. 

For interested participants, our Energy Programs team can walk you through the specifics based on your project’s needs. Contact us at

Power +

Power+ offers HCE members a new resilience option from threats of extreme weather events like wildfires, snowstorms and other outage-causing events while also benefitting the entire HCE membership by reducing wholesale energy costs.

Utilizing Tesla’s Powerwall 2 battery energy storage system, members can store energy directly from the grid or energy generated from on-site solar. Powerwall 2s can provide backup power of 4 to 8 hours on peak usage and 20 to 40 hours with reduced usage, supplying your energy needs during grid outages. Having a solar system alone will not supply this resilience without battery backup.

By allowing HCE to optimize the charging and discharging of your battery during times of high energy demand or renewable energy oversupply, the cost HCE pays for power is reduced. These savings benefit the entire co-op membership. HCE will always leave at least 20% state of charge, and this should allow you at least a few hours of resilience in a worst-case scenario such as an outage after a peak load event.

Under our Distributed Energy Resource (DER) Service Agreement, HCE will pay for the battery and its installation costs upfront for you. You repay HCE with the monthly charge on your bill, which is partially offset by ongoing bill credits that you receive in exchange for periodic control of the battery. Your repayment amount does not include interest or additional fees for ten years.

How the program works?

  • HCE will partner with you to use the battery’s stored power during times of high demand to lower costs. During these forecasted events, the stored energy on your Powerwall 2 will be discharged onto the grid. High demand events will typically be between 4:00 pm and 9:00 pm no more than 10 times per month. You will still have access to power from the grid and should not be impacted by these events.
  • For the remaining days of the year, the battery will be yours to control. You can keep them fully charged in preparation for an outage or you can use the time-based control feature to charge the batteries from your solar and power your home most the of day and evening from your local generation. HCE will also schedule charging from the grid to correlate with renewable energy oversupply. This process will allow HCE to minimize renewable energy curtailment charges and save on power supply costs.
  • During a power outage, the energy stored in your Powerwall 2 system will power your home, providing resilience. If present, solar panels may continue to recharge the system.

How much does it cost?

There are no upfront costs, but members will see an additional charge for the resilience benefits on their monthly bill. This will vary depending on the exact installation costs of your system. The system and installation costs that HCE paid upfront will be repaid to HCE over ten years through the Power+ monthly charge. The energy credits you receive for participating in the program reduce those costs and could continue after ten years if the member wishes to remain in the program.

Frequently Asked Questions

Want to tap into new state & federal tax credits for batteries?

Pay off your Power+ balance by the end of your installation year.

Power+ provides an easy and affordable option for battery energy storage by allowing members to pay off their system over 10 years on their monthly electric bill at 0% interest.

However, with new tax rules, members who are able to fully pay off their system within the year it’s installed may now be eligible for up to 40% federal and 10% state tax credits, potentially saving thousands of dollars in the long run.

Whether you choose to spread your payments out over 10 years at 0% interest or pay your entire balance off by the end of your installation year to take advantage of the tax credits, there are great benefits to both options:
