Featured Member: Great River Hydro
When it comes to renewable energy and environmental stewardship in New England, Featured member Great River Hydro stands out as a leader. Operating five FERC-licensed hydroelectric projects, Great River Hydro’s network includes thirteen generating stations and three storage reservoirs across the Connecticut and Deerfield Rivers. With a combined renewable generation capacity of 589 megawatts (MW), Great River Hydro plays a crucial role in powering our region sustainably.
A Local Powerhouse: The Moore Station in Littleton
In Littleton, New Hampshire, the Moore Dam and Reservoir shine as the crown jewel of Great River Hydro’s operations. Part of the Fifteen Mile Falls Hydroelectric Project (FERC License No. P-2077), the Moore station is the largest hydroelectric facility in New England.
Key features of the Moore Dam and Reservoir include:
- A 3,490-acre, 11-mile-long reservoir managed seasonally at an elevation of 809 feet above sea level.
- 192 MW of generation capacity, powered by four Westinghouse generators and Francis waterwheels.
- An undeveloped shoreline protected by a conservation easement, ensuring natural beauty and ecological balance.
In addition to generating power, the Moore station serves as a hub for local recreation and environmental management. From summer water sports to winter activities like snowmobiling and cross-country skiing, Moore Reservoir is a beloved destination for outdoor enthusiasts.
“Quite a few people utilize Moore Reservoir. It’s a pretty popular place,” notes Matthew Cole, Community Relations Manager at Great River Hydro.
Renewable Energy with a Mission
As a provider of 23% of hydropower generation and 40% of qualified capacity in the ISO New England system, Great River Hydro demonstrates its commitment to renewable energy. The Moore station’s “black-start capability” ensures it can restore the bulk power system during outages, making it a critical asset to the regional grid.
“We produce electricity, but we’re also environmentally conscious,” says Cole. “We comply with license obligations for minimum flows, fish habitats, and other sustainable practices.”
Great River Hydro’s approach to hydropower embodies green energy innovation. Unlike solar and wind energy, which depend on weather conditions, hydropower offers reliable, on-demand electricity. “We just need a phone call,” Cole explains. “We can start up in a couple of minutes.”
Local Impact: Jobs, Conservation, and Flood Control
Great River Hydro’s presence extends beyond energy production. The company creates skilled local jobs, enhances recreational opportunities, and supports conservation efforts. The undeveloped shoreline around the Moore Reservoir is a prime example, preserved through a conservation easement that protects its natural beauty.
Additionally, the Moore station helps manage water flow to mitigate flooding downstream. This capability is essential during periods of heavy rainfall or snowmelt. “We’re preparing for inflow to capture it in the reservoir so it doesn’t cause flooding downstream,” Cole explained .
Recreation and Community Engagement
The Moore Reservoir isn’t just about power—it’s also a hub for recreation. Popular activities include fishing, boating, hiking, and snowshoeing, among others. Great River Hydro actively supports these opportunities by maintaining trails, providing access points, and conducting periodic surveys to better understand visitor needs.
“We did a recreation study this year,” shares Cole. “We’re looking at what people are doing, where they’re coming from, and their preferred methods of recreation.”
One standout event is the Moore Dam fishing tournament, held annually in mid-July. Organized by a separate group with support from Great River Hydro, this event highlights the reservoir’s value as a recreational asset.
Looking to the Future
Great River Hydro’s commitment to innovation doesn’t stop at maintaining its current facilities. The company is continuously exploring ways to enhance energy efficiency and increase production. Plans are underway to develop a new 4.7 MW unit at the Moore station, which will improve power generation while maintaining conservation flows downstream.
“We’re constantly looking at ways to make generation more energy efficient, to better the facilities, and perhaps grow our energy output,” says Cole. “But for the most part, it’s about looking to the future and providing green energy for the region.”
Supporting a Greener New England
For over six decades, the Moore station and its counterparts have been integral to New England’s energy landscape. From their origins with New England Power Company to their current stewardship under Hydro-Québec, Great River Hydro’s facilities have evolved to meet the demands of a changing world.
“We have all these facilities that are carbon-free and able to produce electricity by harnessing water power,” Cole emphasizes. “It’s green energy for sure, and a vital part of the electrical grid.”
Whether you’re kayaking on the reservoir, relying on the electricity generated to power your home, or appreciating the flood control measures that keep your community safe, Great River Hydro’s impact is undeniable.
