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.
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.
The biggest network of charging stations in the northern US
Running cars on electricity instead of oil is the best choice in the fight against climate change. Our subsidiary, Green Mountain Power, has a keen interest in this solution, and has invested in a network of charging stations for electric cars In partnership with NRG's EVgo division, GMP is developing and rolling out a Vermont-wide network of stations. This network is an efficient solution enabling citizens to reduce their polluting emissions, and is a further step toward environmental sustainability for Vermont.
We believe diversity is key to the future of energy. This is why Énergir is involved in developing renewable, liquefied and compressed natural gas, solar and wind power and hydroelectricity.
Énergir is the largest gas distributor in Quebec and Vermont.
Renewable natural gas
Renewable natural gas produced from organic matter.
Liquefied natural gas
LNG is natural gas that changes from a gaseous to a liquid state.
Compressed natural gas
CNG is compressed natural gas that can be used as fuel.
Hydroelectricity generation through our US subsidiary.
Producing electricity takes an unexpected form in Vermont.
