Data for our US energy efficiency programmes is update in October each year for the prior calendar year.

Last year National Grid’s customers in the US gave energy efficiency the green light and implemented energy savings measures that helped mitigate the effects of climate change. 

National Grid offers many electricity and natural gas energy-efficiency programmes for residential and business customers.  For residential customers, the programmes offer various incentives and assistance to make homes more energy efficient through lighting, appliances, high efficiency heating equipment and water heaters, boiler controls, and insulating and sealing measures.  For business customers, the Company’s electricity and natural gas energy efficiency programmes can help improve efficiency at existing or new facilities by lowering operations and maintenance costs through efficient lighting and controls, heating systems, HVAC, windows and insulation, and by participating in other industry-specific efficiency installations and programmes.

During the 2010 calendar year there were close to 180,000 participants in National Grid’s gas energy-efficiency programmes which is an increase of 107% from 2009.  In 2010 there were over 840,000 participants in the Company’s electric energy-efficiency programmes which is a 65% increase from 2009.  Combined, this resulted in over 1 million participants in the gas and electric programmes.

Through participation in these programmes during 2010 customers saved over 13 million annual therms of gas and nearly 520,000 annual megawatt-hours of electricity savings.

More information on our US energy efficiency programmes can be found via the energy service and regions links on our US website.
