Compare to National Grid's average Basic Service prices The table below provides a comparison between Worcester's current prices and the most recent 12-month average of National Grid's Basic Service prices. Because National Grid’s fixed Basic Service prices change so frequently (every 6 months for residential and commercial accounts and every 3 months for industrial accounts), using an average price provides the most accurate comparison. However, if you wish to know National Grid's current 6-month price, please visit the Prices page or visit National Grid's Supply Costs web page and scroll down to Basic Service Rates.
	Residential	Commercial	Industrial
The most recent 12-month average National Grid price ($/kWh)	$0.15357	$0.14109	$0.12936
Monthly electricity supply charges ($/month)

Note: This calculator calculates equivalencies using information provided by the EPA’s Greenhouse Gas Equivalencies Calculator. Greenhouse gas emissions avoided are calculating using the most recently available Massachusetts Department of Environmental Protection (DEP) emissions factor.

Savings cannot be guaranteed

Please note that, while the Green Worcester ElectriCITY Municipal Aggregation Program seeks to provide a price that is equal to or lower than National Grid’s average Basic Service prices, there is no guarantee of savings compared with National Grid’s Basic Service prices because future National Grid prices are unknown.
