Benefits of ETS

With appropriate rates in place, ETS can lower heating bills since it relies on electricity generated during off-peak hours. Mainers know how expensive it can be to heat with oil. While oil prices have declined since their peak during the summer of 2008, prices are likely to rise again once world economies recover from the global economic downturn.

ETS can play a major role in supporting the development of clean renewable energy in Maine, especially electricity generated from wind, hydro, biomass and tidal sources. Wind blows the strongest during the winter, our coldest months, and on average blows more during off-peak hours than on-peak hours. Electric thermal storage represents a beneficial use for that off-peak wind power by converting it to heat (at 100% efficiency!) that can be released to provide space and water heating 24/7.

By helping Maine transition from its near-total dependence on fossil fuels for home heating purpose to the use of renewables, ETS can help the State meet its goal of reducing greenhouse gas emissions and achieve a greater degree of energy independence. In addition, ETS enhances Maine’s economy by keeping energy related dollars and jobs in the State. The Governor’s Office of Energy Independence and Security refers to money spent on oil as a “Petro-Dependence Tax” which costs Maine billions of dollars a year. Maine has an abundance of wind resources and a growing number of wind farms. By increasing the demand for off-peak electricity, the use of thermal storage technology allows dollars otherwise spent on imported oil to remain here instead.
