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
