Grid Transformation: Green Tariff Deals

Large-scale renewable energy buyers are transforming the electricity market one deal at a time. This interactive graph explores the renewable contracts signed by large-scale energy buyers and monopoly utilities via green tariffs.

A green tariff is a price structure, or an electricity rate, offered by a local utility and approved by the state's PUC that allows eligible customers to source up to 100 percent of their electricity from renewable resources. Through a green tariff, customers are able to purchase both the energy from a renewable energy project, at a large-scale, and the associated Renewable Energy Certificates. The green tariffs included in this chart are not extensive. Only those which have been executed have been included. The Emerging Green Tariffs in U.S. Regulated Electricity Markets publication identifies the full list of available green tariffs. The U.S. Renewable Energy Map: A Guide for Corporate Buyers displays which states offer green tariffs, amongst other utility renewable energy products.

The Technical Note describes the scope and analytical methodology for the renewable energy options identified in the map and this bar chart.
