Near-Zero-Energy Homes help electric utilities meet record system peaks

Five near zero energy houses (ZEH) are under test at an energy research park near Oak Ridge, TN. Data from
2006-2007 show that these homes have ~7 kW lower summer peak electric demand than typical conventional
homes in the same region. Combining 17,000 such homes in a “zero energy neighbourhood” could provide a
utility with peak demand management capability equivalent to a 120 MW power plant.
