We're working hard to create new energy infrastructures that will fuel society's growth today without compromising the needs of future generations. We envision a system where traditional power plants will be supplemented by energy sources such as distributed generation, which produces electricity safely, cleanly and reliably near or at the point of use, rather than at large central power stations. In 2003 we celebrate our foundation, our values and our past, as we look to energize the future.
