Electricity distribution

Green Mountain Power, a subsidiary of Énergir, is Vermont’s largest electric distribution company

GMP serves more than 70% of the Vermont market and has over 260,000 customers. The State of Vermont is known for being proactive in environmental matters, and Énergir's operating philosophy is reflected in the sustainable development values that are firmly rooted there. GMP is always striving to improve and innovate in order to offer its customers clean, reliable, affordable and smart electricity.

About electricity distribution

Traveling at 300,000 km/s within the distribution network, electricity passes through cables suspended from towers connecting the generating stations to source substations, which lower the voltage. It then reaches the satellite substations, which further reduce the voltage. Electricity leaves the satellite substations through underground lines which then change into overhead lines. Transformers attached to poles lower the voltage one last time, allowing for power distribution to the consumer. 

Diverse sources

Green Mountain Power generates a portion of the electricity it distributes but most of its supply is purchased from different producers. Its supply portfolio comprises several sources of power generation, including hydroelectricity (GMP buys Hydro-Québec 23% of the electricity it distributes) and wind and solar power. GMP also buys electricity produced from cattle manure, a process by which dairy cow excrement is transformed into clean electric energy.

Innovation at the heart of the company

To remain at the leading edge of energy creation and distribution, Green Mountain Power established the GMP Energy Innovation Center (EIC), located in downtown Rutland. There, GMP employees share their know-how on a daily basis to develop promising innovative approaches for Vermont.
