Power+FLEX

Power+ is now Power+FLEX

Your backup power partner.

  • Increase your home's energy resilience
  • Help the co-op reduce our collective peak energy costs
  • Receive an upfront rebate and a monthly bill credit for sharing your your stored energy with the grid during times of peak electricity demand
  • Choose how much of your battery system you want to enroll

Battery energy storage systems are an effective way to be able to keep your home powered during an outage—and Power+FLEX will help offset some of the cost of your system.

Since extended power outages are rare, Power+FLEX also allows you to maximize the benefit from your batteries on other days of the year. By letting us optimize the charging and discharging of your battery during times of high energy demand or renewable energy oversupply, you’ll earn a bill credit for helping us reduce our wholesale power costs.

That saves everyone money, supports clean energy, and helps build energy resilience throughout our service territory.

How does it work?

Solar and storage are better together.

Times we may charge your batteries From the grid
  • Before select periods of high demand, in preparation to dispatch the power back onto the grid later.
  • During periods of renewable energy oversupply.
DURING SELECT PERIODS OF HIGH ELECTRICITY DEMAND
  • A few times per month, we may release some of your excess stored energy onto the grid, in exchange for the monthly bill credit.
  • You also get full credit for the energy we pull onto the grid, via the reverse flow of your net meter.​
During all other times
  • The battery is yours to control.
  • For example, store your excess solar generation to use at night.

What do other members say about Power+FLEX?

“I couldn’t be more excited about the program. During the summer months my Powerwalls and solar take care of my house power needs 100%. In the fall, the Powerwalls help supplement, but I still require grid power. The program is great to be majority self-powered and helps the grid with capacity to feed power. I would highly recommend this Power+ to anyone and think everyone should sign up because it is a great deal for homeowners.”

Frequently Asked Questions: Battery Charging & Discharging Events

For Power+FLEX, what happens when HCE charges and discharges your batteries?

How often will HCE be taking the stored energy from my batteries?

  • HCE may initiate withdrawal or delay charging during times of peak demand.
  • These times are usually between 4:00 and 9:00 p.m.
  • Events will usually last 2 to 3 hours in duration.
  • HCE will target a limit of 100 peak demand event hours in a calendar year, although that limit can be revised if conditions warrant.

Will HCE initiate charging of my batteries, and if so, when? 

  • HCE will charge the batteries from the grid during times when energy is least expensive or during times of renewable oversupply.
  • Renewable oversupply will most commonly take place between the hours of 11 a.m. and 4 p.m. and can occur any day of the year.
  • Renewable oversupply events are expected to last 3 to 10 hours in duration.
  • HCE anticipates around 30 days may include peak renewable production hours.
  • HCE will target a maximum limit of 90 renewable oversupply events in a calendar year, although that limit can be revised if conditions warrant.
  • HCE will not operate the batteries more than 10 times per month. 

Can I request that HCE leave me with more than 20% stored power when they pull for a peak event? 

  • No. 20% is the minimum 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. HCE has based the bill credits on this minimum state of charge, and it is built into the calculations.
  • The amount of time a battery will provide backup power for your home depends on your battery capacity and electric usage during that time.
  • Members interested in maintaining a higher percentage of stored power can do so through Power+FLEX.

Do I have full control over my battery system when HCE is neither charging nor discharging my batteries? 

  • Yes, outside of charging, discharging, and a short hold period after a demand event, members have full control over their batteries. 240
