What are Transmission Distribution Utility (TDU) Surcharges?
TDU surcharges are the pass-through fees that are assessed by the utility company in your area. These fees cover the cost of transmitting and delivering energy to your facility from the power grid.

Renewable Energy Questions
What is Renewable Energy?
Energy sources that are either inexhaustible (solar, wind, geothermal) or replenished over a short period of time (hydro, biomass) are considered renewable. Natural gas and coal, for example, are not renewable because their use consumes gas and coal reserves at a much quicker rate than they can be replenished. Nuclear is not derived from fossil fuels but has negative environmental impacts like harmful radioactive waste byproducts.
Learn more about renewable energy like wind and solar.
What is Cleaner Electricity?
Most people aren’t aware that the traditional generation of electricity is the leading cause of industrial air pollution in the U. S. and creates more CO2 than any other sector.
“Cleaner electricity” is from generation sources that produce little to no air pollution (carbon dioxide, sulfur dioxide and nitrogen oxides) and/or radioactive waste, especially when compared to traditional sources of electric generation (i.e., coal and nuclear). Sources of cleaner electricity include wind, solar power, biomass, geothermal and hydropower.
What are Carbon Offsets?
Carbon offsets are investments in projects that reduce or avoid carbon dioxide (CO2) emissions. After individuals or businesses try to directly reduce their emissions as much as possible, they can purchase carbon offsets to balance out any emissions that are still remaining, bringing their overall carbon footprint down to zero. Learn more about Carbon Offsets.
What is LEED?
Leadership in Energy and Environmental Design (LEED) is an internationally recognized green building certification system developed by the U.S. Green Building Council. Visit LEED 101 for more information.
What is the EPA Green Power Partnership?
The Environmental Protection Agency’s Green Power Partnership is a voluntary program that supports the purchase of green power by businesses and organizations. Learn more about the EPA Green Power Partnership program and Green Mountain customers who participate.
What do I do if I close or move my business?
In the event that your business is closing or you are moving to a new location, please contact our Customer Care Center. Our professional Customer Care Specialists will walk you through the process of moving out the old location and moving into a new one.
Who do I call about power outages?
