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.
Terms and Conditions for HCEs control of Battery Energy Storage Systems (BESS):
- HCE may initiate withdrawal from or delay charging of the BESS during times of renewable oversupply or peak demand.
- HCE will target cycle the BESS no more than 120 times in a calendar year.
- HCE will limit events to no more than 10 per month.
- A Distribution Flexibility credit to the member for their BESS is offered at $10.30/kW/Mo, ($51.50 per Powerwall 2 each month) where;
- kW is defined as the lesser of (kWh*(1-SOCmin)/2 or (kW max continuous).
- SOCmin = minimum state of charge as defined by the battery manufacturer (in a % form), expressed here as a ratio to full state of charge energy volume. Tesla Powerwall SOC requirements reserve 20% SOC for the Consumer.
Full details regarding Distribution Flexibility Tariff credits are tied to the terms of the Distributed Energy Resource Service Agreement for Power+.
Power+ Program Service Agreement
- You are eligible to add up to five Tesla Powerwall-2s per Holy Cross account.
- You must have had service with Holy Cross for 12 months and have no more than 2 delinquent payments in 12 months.
- If you participate in Power+ you cannot also enroll in our Peak Time Payback Program or our Time-Of-Day rate.
- We coordinate with you and a certified Tesla installer to complete the installation and activation.
- Enrollment in the Power+ Service Agreement allows for the payback of the system costs and enrolls you to receive credits from Holy Cross through the Distribution Flexibility Tariff.
- Repayment of the installation costs occurs at a monthly fixed rate over a 10-year period. Repayment amounts vary based on the installation costs. HCE owns the system for the 10-year payback period unless you pay back the installation costs prior to 10 years.
- The Distribution Flexibility Tariff credit will be provided monthly for allowing HCE to control the batteries during times of peak demand or renewable energy oversupply.
- HCE will always leave at least 20% state of charge available for outage protection at your site.
