GMP expands battery options for customers, adding Enphase energy systems

COLCHESTER, Vt. – Green Mountain Power’s ongoing commitment to deliver innovative storage programs to benefit customers expanded with the announcement of a pilot program with Enphase Energy Systems. As part of the pilot program, customers lease or purchase two Enphase IQ Batteries for their home. Customers agree to share access to the batteries to cut power demand during expensive energy peaks when people are using a lot of energy, which helps lower costs for all.

Customers can choose to lease Enphase batteries for a monthly payment of $65 for ten years, or they can buy their own for $6,500 and enroll their Enphase batteries in GMP’s “Bring Your Own Device” (BYOD) program. The BYOD program allows customers to receive an upfront incentive in exchange for allowing GMP to tap into the stored energy during peak usage times, helping to lower costs for all customers.

“We are excited to offer customers more options for batteries, building off our already successful storage programs, as we create a stronger, flexible, and more resilient energy grid,” said Josh Castonguay, GMP vice president and chief innovation officer. “Our growing network of stored energy continues to deliver savings for all customers, helping cut carbon and costs. Expanding this groundbreaking work with another pilot program will allow more customers to access storage technology, while increasing the savings through a shared network of neighbor helping neighbor.”

“We’re proud to work with Green Mountain Power on this program to offer Vermont homeowners Enphase IQ Batteries and IQ Microinverters,” said Dave Ranhoff, chief commercial officer at Enphase Energy. “Our industry-leading software and hardware make building and deploying virtual power plants easier than ever. And none of this would be possible without the professionalism and experience of our local installer partners, who all offer a best-in-class experience for our mutual customers.”

Enphase and GMP are currently working with four Vermont installers and are encouraging more installers to be part of the program. Customers can choose to work with HB Energy, Power Guru, Southern Vermont Solar, or SunCommon.

“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.”

Last year, GMP’s growing network of shared stored energy reduced about $3 million in costs for all customers by cutting power demand during energy peaks.

The Enphase battery lease program is open for 100 customers, and you can learn more here. Or sign for the BYOD program here.

  1. Here we go: reinventing the wheel again, fixing what ain’t broke, and making us more and more vulnerable to long term inaccessibility to vital infrastructure… because its outsourced and insourced. And made of materials that come for questionable mining practices (human and environmental), and pays a third or fourth party – who has no obligation to the customer.
    I get a lot of – we have no control over that in reply to issues of connectivity whether electric or telecomm… and its the third party issue. The one you can’t email or write to communicate with.
    Sounds like a sound plan.

  2. I installed two Electric Vehicle chargers at my home because my kids drive EVs. Then I noticed that GMP was providing credits to those who did what I did. The Catch 22. Because I didn’t install a GMP charging station, I didn’t qualify for the credits. Talk about a conflict of interest.

    I also just learned that there are battery systems coming to market that, when fully charged, can provide 100% of the electricity needed in a typical 3 bedroom house for up to ten days.

    Yes, this is new technology. It’s very expensive, for now. But unless GMP gets their hands on the equipment and can skim a commission from every sale, I suspect the technology will be squandered.

    Why else do you think GMP agrees to pay two times more for wholesale wind and solar power rather than purchase more Hydro Quebec electricity? Even as GMP and HQ are owned by the same conglomerate. It’s because HQ power doesn’t qualify for the lucrative ‘carbon credit’ market.

    This is what happens when free markets are controlled by government regulated cronies. It’s what happens when VIPRG board members lobby the Vermont legislature for solar power subsidies and then sell their solar company (Sun Common) for millions of dollars. It explains the relationship between Vermont’s current U.S. Representative (Peter Welch – who sits on a House energy committee) and one of the three Vermont Public Utilities Commissioners (Margaret Cheney) who determine Vermont’s energy future. And yes, Ms. Cheney is none other than Mr. Welch’s wife.

    Be it energy, healthcare or education, the game is rigged. Pay, or don’t play.

    • Jay – For your kids’ sake, you might be interested in this article from March 23 from Principa Scientific International, on EVs causing possibly causing cancer:

      Hybrid and electric cars may be cancer-causing as they emit extremely low frequency (ELF) electromagnetic fields (EMF).

      Recent studies of the EMF emitted by these automobiles have claimed either that they pose a cancer risk for the vehicles’ occupants or that they are safe.

      Unfortunately, much of the research conducted on this issue has been industry-funded by companies with vested interests on one side of the issue or the other which makes it difficult to know which studies are trustworthy.

      Meanwhile, numerous peer-reviewed laboratory studies conducted over several decades have found biologic effects from limited exposures to ELF EMF. These studies suggest that the EMF guidelines established by the self-appointed, International Commission on Non-Ionizing Radiation Protection (ICNIRP) are inadequate to protect our health. Based upon the research, more than 240 EMF experts have signed the International EMF Scientist Appeal which calls on the World Health Organization to establish stronger guidelines for ELF and radio frequency EMF. Thus, even if EMF measurements comply with the ICNIRP guidelines, occupants of hybrid and electric cars may still be at increased risk for cancer and other health problems.

    • Instead of using taxpayer money to provide funding for research and for bridge energy (like natural gas) they squander it on subsidies for the rich. It also buys votes. If solar and batteries were such a good idea they wouldn’t need subsidies. It just drives up the cost for those who can least afford it. Meanwhile the quest for the Magic Battery continues…

  3. Gee, why does GMP need this program at all? Why are there peak problems? Is there no other form of reliable dispatchable power available? What happened to coal and nuclear?

    GM advises Bolt owners to park OUTSIDE and 50 feet away from other cars.
    Who in there right mind would risk attaching a potentially unstable Lion battery pack to their house?
    Did they talk to their insurance company first?

    It appears this is being done backwards. GMP should be PAYING their customers to provide a safe location for battery storage.

  4. Never, and I mean never has any electric company lowered the cost of electricity.
    Lie they will!

  5. My own pilot program is to have a generator for the boilers, and one for lights and refrigerator. Costed about $600 all together, including a switch for the boiler feed from a generator. I own it all. And for the ‘wokes’ among us, I spent my lifetime in power generation, including the control room of plants. My way will last much longer then the 10 years your batteries will last. But hey, give your money to the owners in Canada if it makes you feel better.

      • I have two because I wanted one that can be dedicated to running the control electronic controls and circulators on a wood boiler. — If its fired, and the power goes out for more then an hour, I either have to put the fire out, or power it up. Most outages we see in Bennington are an hour or less, but you never know.

        I wanted the other generator, because if I need to cook in an electric frying pan, run a couple of lights, etc. I don’t want it tripping the generator powering the heat.

        Now the safety valves on the wood boiler work, but it trusting the system to refill with water when the lights are out is dumb.
