Vermont’s progressive utility Green Mountain Power (GMP) announced its latest battery service tech deal with Enphase. GMP will offer Enphase’s Energy Systems to its customers in a battery lease grid services pilot program. Homeowners can also enroll in GMP’s “Bring Your Own Device” (BYOD) grid services program, which enables customers with their own Enphase Energy Systems to participate and earn an up-front incentive.

As for Enphase, they are launching Grid Services Manager, a distributed energy resource management system (DERMS) that GMP will use to manage virtual power plants with Enphase Energy Systems. Enphase expects to offer this software product for utility grid managers and distributed energy resource aggregators in the future.

“This new battery backup leasing program makes getting an Enphase Energy System with its exceptional IQ Batteries an even easier decision for Vermont homeowners,” said Liam Madden, director of solar energy at HB Energy Solutions. “With the new IQ8 microinverters, our customers will be able to easily expand their home battery system over time, giving them even more peace of mind about their energy future. This partnership allows the homeowners, local contractors, and utilities to use Enphase’s state of the art technology to help create a more reliable, affordable, and cleaner grid for all of Vermont.”

Terms of the program

The lease program will provide 100 eligible customers with two Enphase IQ Battery 10 units for $65 per month for ten years, or for a single payment of $6,500. That cost does not include installation. Homeowners benefit from reliable backup power, while also sharing stored energy during times of high demand to help reduce overall costs for all GMP customers.

Alternatively, homeowners can buy a new Enphase Energy System or enroll their existing system in GMP’s BYOD program, which doesn’t have a limit to the number of participants and enables them to earn money with their Enphase IQ Batteries through a one-time, upfront incentive.

Eligible customers can sign up and monitor participation in the Enphase App and will receive an upfront payment of up to $9,500 with four Enphase IQ Battery 10s. If homeowners are retrofitting an existing solar system in one of the areas of the state where battery power is needed most, they may be eligible to receive an extra $100 per kilowatt. Program participants will be enrolled for a term of a minimum of ten years.

Vermont homeowners can now also choose to install Enphase’s revolutionary IQ8 solar microinverters. IQ8 eliminates sizing restrictions on pairing an Enphase IQ Battery with the IQ8 solar system. This allows homeowners flexibility to start small by backing up essential loads only and then grow their home battery systems over time to better meet their needs.

“We rely on Enphase IQ microinverters for most of our rooftop solar customers. Bringing the same integrated communications platform with detailed energy monitoring and solar production information for each solar panel, and now for energy storage, is very exciting,” said Simon Piluski, founder of Southern Vermont Solar. “GMP and Enphase are great partners with us in serving our community’s energy needs now and into the future.”

The Enphase IQ Batteries feature Lithium Iron Phosphate (LFP) battery chemistry, which provides a long cycle life and safer operation through excellent thermal stability. The batteries are equipped with Enphase Power Start technology, which helps power-up air conditioners and well-pumps. Enphase IQ Batteries accommodate over-the-air software upgrades and come with a 10-year limited warranty with an optional 5-year limited warranty extension available for purchase, while Enphase IQ8 solar microinverters come with a 25-year limited warranty.
