Reading Your National Grid Electricity Bill

Two types of charges make up your electricity bill. Those are delivery charges for safe and reliable energy delivery and supply charges for the electricity that you use.

Delivery Charges

Charged by National Grid to maintain electricity infrastructure like poles and wires. This set rate that doesn’t change when you switch providers.

Supply Charges

Supply charges are what you pay for the electricity that you use. By default, these charges are set by National Grid and may fluctuate based on wholesale energy market conditions.

Financial Assistance for National Grid Customers

Federal, state, and utility-level programs provide energy bill assistance, discount rates, and debt relief to eligible National Grid customers (with a focus on Massachusetts residents).

Federal Assistance Programs

• LIHEAP (Low Income Home Energy Assistance Program): A federally funded grant program that pays a direct benefit to National Grid on behalf of income-eligible households to offset seasonal heating and electric bills. Eligibility is based on household size and state median income (generally up to 60% SMI).
• WAP (Weatherization Assistance Program): Provides eligible low-income homeowners and renters with full-scale energy-efficiency improvements at no cost—including air sealing, insulation, and heating equipment repair—to permanently reduce long-term electric and gas usage.

State-Level Programs

• Good Neighbor Energy Fund: Managed in partnership with the Salvation Army, this emergency state fund provides one-time financial grants to residents experiencing temporary financial hardship who earn between 60% and 80% of the state median income—making it a crucial bridge for households that earn too much to qualify for federal LIHEAP grants.
• RAFT (Residential Assistance to Families in Transition): Provides short-term emergency financial relief to low-income families at risk of utility shut-offs, housing instability, or displacement.
• Mass Save Low-Income Energy Affordability Program: Offers income-eligible households enhanced rebates, zero-cost weatherization, and no-cost home heating/cooling system repairs through local Community Action Agencies (CAPs).

National Grid Utility-Specific Programs

1. Tiered Discount Rates (R-2 Class)

National Grid offers a discounted electricity supply and delivery rate to income-eligible residential customers. Discounts range from 32% up to 71% off your monthly electric bill depending on household income tiers and size.

How to Qualify: You automatically qualify if you participate in public benefit programs like MassHealth (Medicaid), SNAP, SSI, TAFDC, WIC, or LIHEAP.

2. Arrearage Management Program (AMP)

Also known as the Forgiveness Program, AMP helps customers with past-due utility debt erase their balances.

Requirement: Your account must have a past-due balance of at least $300 that is 60+ days overdue, and you must be enrolled in the Low-Income Discount Rate.

How it Works: You are placed on a fixed monthly budget plan. For every monthly bill you pay on time, National Grid forgives 1/12th of your past-due debt (up to a maximum of $12,000 per year).

3. Special Medical Protections & Budget Billing

Special Protections: Customers facing financial hardship who have seniors (65+), infants under 12 months, or individuals with serious medical conditions/life-sustaining equipment living in the home can register for shut-off protection.

Balanced Billing/Budget Plan: Spreads your total annual energy charges evenly over 12 months to prevent drastic bill spikes during high-use summer and winter months.
