Offered at no cost to the customer, the new energy management technology options and tools are expected to help customers learn how much energy they are using throughout the day, allowing them better information to make smarter choices about ways in which they can save energy.

The technology options for residential customers include online and mobile energy use applications to monitor and control electric use anytime, digital picture frames with real-time electricity usage information, smart thermostats, as well as electricity control devices to remotely monitor and control home equipment and appliances.

Commercial customers are also expected to have choices of similar technology options.

National Grid has upgraded over 80% of the electric system associated with the program with new automation and infrastructure-enhancing devices that will enhance electric service reliability and power outage response.

National Grid Massachusetts president Marcy Reed said the company has reached a significant milestone in its program preparing to deliver full benefits to the customers.

"Our customers depend on us to reliably deliver their electricity, so National Grid is leveraging new technologies to build a smarter, more resilient electric network," Reed added.

The company is expected to offer time-based pricing plans to help customers achieve even more energy savings in late 2014, as part of the next phase of the program, which aims to empower customers to save energy, increase electric service reliability and improve response to power outages.
