GMP Partners with Vermont State Parks for First ePark at Emerald Lake State Park in East Dorset

02 September 2015

Park Will Be Removed from Electric Grid and Powered by Solar and Battery
 
East Dorset, Vt. – As Vermonters enjoy the last warm days of summer and the beautiful 
outdoors, one state park is about to take our green image to a whole new level by going 
green and off the grid. Green Mountain Power is partnering with the Vermont 
Department of Forests, Parks and Recreation to transform the bulk of Emerald Lake 
State Park in East Dorset into an ePark, powered entirely by solar and the new Tesla 
Powerwall battery for storage.
 
“It is so exciting to partner with customers on this energy transformation, and bringing 
new energy technology, and the independence that comes with being off the grid, to 
Vermont’s state parks is a great step forward,” said Mary Powell, President and Chief 
Executive Officer of Green Mountain Power. “I’m thrilled that we can cost-effectively 
provide incredibly reliable, renewable power to one of Vermont’s state parks by taking 
it off the grid. Emerald Lake State Park is a great example to Vermonters, and the 
thousands of visitors to the park each year, of what our energy future will look like. This 
project will show how we can provide cost-effective power that is clean and highly 
reliable, while being generated closer to home.”
 
Emerald Lake State Park is currently served by a standard power line extending a half 
mile through swamps, marshes and rough, heavily forested terrain to the park. The line 
experiences multiple outages each year where lineworkers have to make costly repairs 
due to fallen trees and the remote location of the lines. By installing solar power paired 
with the Powerwall battery for storage, the state park will increase reliability and keep 
guests comfortable without the need for power lines. A successful project will allow 
GMP to retire the entire line.
 
The cost to install the solar and storage system is approximately 20% less than the cost 
to rebuild the line to Emerald Lake State Park. And there are additional maintenance 
savings, as every year it costs about $7000 to $8000 for lineworkers to repair damaged 
and downed power lines.
 
Denis Lincoln, at the Vermont Parks Division said, “We loved this idea as soon as GMP 
came to us with a creative way to power our facilities at Emerald Lake, lower costs and 
improve reliability. This is a model for how to use cutting edge technology and 
innovation to benefit visitors to this great park. I hope we see more of this across 
Vermont.”
 
Through its partnership with Tesla, GMP is one of the first utilities in the country to offer 
solar and battery back-up to customers, offering the company’s groundbreaking 
Powerwall.  GMP will receive approximately 500 Tesla home energy storage systems 
starting in October. In addition to the Powerwall, GMP offers products and services like 
the comprehensive eHome program to help customers save money, reduce fossil fuel 
use, and be more comfortable.
 
“As the Energy Company of the Future, GMP is transforming from the 100-year-old grid, 
which includes poles and lines like those you see at Emerald Lake, to one where more 
clean and cost effective power is generated and stored closer to home. GMP is offering 
innovative products and services to help customers save money and use less energy,” 
Powell concluded.
 
Work at Emerald Lake will start in the spring.  For more information about Vermont’s
