Energy-efficiency policy in the electric power sector has often focused on consumers through end-use energy-conservation programs and incentives. However, significant opportunities also exist to reduce energy use through investments in the electric power supply infrastructure. Besides reducing the losses in the infrastructure, there are also opportunities to reduce energy use on the customer side and peak demand through voltage management on the distribution system. A demonstration project has been designed to address the full range of these opportunities for energy savings. In many cases, the investments can be attractive alternatives to customer-side incentives and initiatives.
