The first American utility company to offer this innovative system even has two plans for customers interested in the Powerwall. In 2014, Vermont had an estimated population of 626,562 people. GMP's own statements claim that 75% of Vermont residents are their customers.
However, Green Mountain Power isn't the first company to offer the Tesla Powerwall, as our previous story shows. Back then, Tesla's Powerwall was available for $5,000 from a company specialized in solar energy solutions.
The most affordable option is leasing, through which the customer receives a credit of $37.50 on their monthly electric bill. Customers who sign up for this plan will allow the utility company to access stored energy to meet peak demand on its grid. This saves money for the electricity provider without building a huge Powerwall facility dedicated to such necessities.
If future Powerwall customers want to keep all the power to themselves, they have to purchase the unit for $6,500. Green Mountain Power hasn't specified if the price includes installation and a specific inverter. In exchange for the sum, the customer gets a backup power supply in the event of an outage.
Either way, the energy stored in the Powerwall units delivered by Green Mountain Power is obtained from residential solar panels. This makes the Tesla Powerwall solution work in an environmentally thoughtful manner, as its makers intended.
The first ten customers will receive their Powerwall units over the course of January 2016. According to Teslarati, Green Mountain Power will purchase 500 Powerwall units over the course of next year.
For those unfamiliar with the Tesla Powerwall, the system allows its customers to store energy from renewable sources and use it whenever necessary. In the best case scenario, the user could use several Powerwall home batteries to power their home independently from the utility grid. Other applications involve using collected solar power at night in order to lower reliance on conventional power plants, usually operated on coal or other forms of non-renewable energy.
