In May of 2012 National Grid approached EFI to develop an online site through which a 7-day programmable thermostat could be purchased by National Grid's gas customers in Massachusetts and Rhode Island.
National Grid was able to offer a $35.00 incentive, and cover the shipping cost. An EFI e-commerce site was launched the following month through which the utility's customers in either state could purchase a qualifying thermostat with a usual retail price of $39.95 for $4.95 with free shipping.
National Grid marketed the program through bill messages, email marketing, and a bill enclosure.
PEFI captured customers' gas utility account numbers, verified eligibility, enforced a purchase limit of two programmable thermostats per account number during the online process, as well as handled all aspects of customer support, inventory management, payment, and order processing.
The utility's expectation was to put 3,000 thermostats into customers' homes. Over 12,000 thermostats were ordered.
* EFI's estimate, assuming savings of 75 ccf per thermostat (Gasnetworks, Validating the Impact of Programmable Thermostats - Final Report, prepared by RLW analyrtics, Middleton, CT, January 2007).
