National Grid in Massachusetts has filed its electric rates for industrial and other large business customers who purchase "basic service" power supply from the utility for the period February 2015 through April 2015.

Back in September, National Grid filed winter electric rates for customers who do not shop for a competing electric supplier, and who instead take "basic service" for their power supply needs.

At that time, National Grid announced six months worth of residential and commercial electric rates, with rates of about 16¢/kWh, but only set industrial rates for the three month period ending January 2015, due to the unique nature under which industrial rates change every three months.

Now, National Grid has filed with the Massachusetts Department of Public Utilities basic service rates for February, March, and April 2015.

The new rates continue the trend of significantly higher electric rates for 2015, versus 2014.

National Grid's specific industrial basic service rates (rate classes G-2, G-3) vary by whether the customer is in National Grid's north, south, or west zone, but rates are generally in the same range across each zone.

Specifically, the National Grid Massachusetts basic service rate for industrial customers will be about 19¢/kWh for February 2015, 13¢/kWh for March 2015, and 8.5¢/kWh for April 2015.

For industrial customers who take the fixed National Grid rate option, the rate for February through April 2015 will be 13¢/kWh.

Elsewhere in New England, Public Service of New Hampshire (PSNH) has announced that it will, in fact, be increasing its electric supply rate on January 1, 2015 for customers who do not shop.

In the fall, PSNH had forecast a marginal decrease in its electric supply rate for 2015, but now says a rate increase is needed, citing an increase in the cost of fuel and energy needed to meet overall customer demand.

PSNH is now seeking to set the default service rate at 10.56¢/kWh for the period starting January 1, 2015, versus the current rate 9.87¢/kWh.  This rate would apply to all customer classes if the customer buys their power supply from PSNH.
