  • Combined Heat and Power (CHP)

    CHP is an efficient and reliable approach to generating power and thermal energy from a single fuel source that offers energy and environmental benefits over electric-only and thermal-only systems in both central and distributed power generation applications. CHP systems consist of a number of individual components, prime mover, electric generator, heat recovery, and electrical interconnection that are configured into an integrated whole. CHP systems achieve typical effective electric efficiencies of 50% to 70% - a significant improvement over the average efficiency of separate heat and power systems. The following websites offer a wide variety of tools, resources, and information.
  • Energy Service Companies (ESCOs)

    An ESCO, or Energy Service Company, is a business that develops, installs, and finances projects designed to improve the energy efficiency and maintenance costs for facilities over a seven to 10 year time period. ESCOs generally act as project developers for a wide range of tasks and assume the technical and performance risk associated with the project.
  • Load Management and Demand Response

    Demand Response is reducing or shifting facility electricity use in response to either high wholesale electricity prices or reliability problems on the electricity grid. It has the added benefit of assisting in managing load shape at a facility, which can help in negotiating a lower price with a competitive electricity supplier. While energy efficiency is reducing electricity use for many hours per day for most of the year, Demand Response is reducing or shifting electricity usage for only a handful of hours per day a few days per year. The investor owned utilities in Massachusetts administer the ISO program, and also offer services to help their customers monitor and manage their electric usage. If you buy electricity from a municipal provider, contact them to determine the load management and Demand Response services they provide.
