Who We Are

Changing lives by unleashing the power of efficiency

Our Story

Efficiency Nova Scotia Corporation was established in 2010 to manage electricity Demand Side Management or DSM initiatives within Nova Scotia. These initiatives were funded by a DSM charge on electricity bills. In 2014, legislative changes required DSM initiatives to be provided by a franchise holder. The franchise holder, now known as EfficiencyOne, has the exclusive right to supply NS Power with reasonably available, cost-effective efficiency and conservation activities for a ten-year term. The Efficiency Nova Scotia franchise is a public utility regulated by the Nova Scotia Utility and Review Board, which approves agreements between NS Power and EfficiencyOne on the level of DSM activity. The cost of these activities is included in electricity rates.

During 2015, the Board approved a three-year, $102 million investment in DSM activities. The Board Decision can be viewed here.

EfficiencyOne Services was established in 2015 to bring our experience and expertise to more people and places.
