An ESID number is your Electronic Service Identifier. This number is given by your electric utility company to uniquely identify your property address. While the numbering system may differ between electric transmission and delivery utility companies, each ESID is unique to a meter.
Many power providers are now offering green plans, which are plans that offer energy produced from renewable, non-polluting sources. These green plans may usually cost a little more than traditional energy plans that derive their energy from traditional fossil-fuel sources, however many energy-plan shoppers are choosing to pay a little more in order to contribute to a cleaner environment in a more sustainable world.
Deregulated energy markets are where energy utility companies are not able to sell electricity directly to the end consumer. Instead, the client can choose between many REPs (Retail Electric Providers), this creates a competitive market that results in lower prices for homeowners and businesses.
