Adding solar panels and switching rate plans can lower your New Hampshire Electric Cooperative electric bill

Updated: October 22, 2020

There are three ways you can reduce your NHEC bill: changing your habits, switching your rate plan, and adding solar panels.

You've probably heard a lot about reducing energy consumption by doing things like switching to LED lightbulbs and adding insulation to your walls, but these fixes are relatively easy compared to the far more impactful step of making changes to your lifestyle.

The second thing you can do is switch your rate plan. NHEC offers time-of-use billing that can help you save money by shifting your usage of energy-intensive appliances to off-peak hours, and there may be other options for you as well.

Finally, you can reduce or even eliminate your electricity bill by installing solar panels on your home.

How much can I reduce my New Hampshire Electric Cooperative bill by switching to a different rate plan

For some people, the savings from switching rate plans may only be a few dollars per month, but for many it can be $20-$100 per month. That's between $240 and $1,200 that you may now be paying to New Hampshire Electric Cooperative each year for no reason.

Finding out what's available to you is as simple as a phone call or email to New Hampshire Electric Cooperative. Even a small savings can be worth it.

Are solar panels worth it for New Hampshire Electric Cooperative customers?

Probably. With the state’s $1,000 solar rebate program and local options for property tax abatements, home solar panels can make a lot of sense for New Hampshire Electric Cooperative customers. Unfortunately, NHEC imposes a member surcharge for anyone who wants to go solar every month. That amount can make your long term solar investment picture look not as bright. NHEC’s solar rate plan also allows you to at least get some credit on your power bill for the excess solar electricity your panels produce which you can’t use onsite. Your credits, while accruing at a much lower rate than you pay for electricity, roll over to the next month’s bill.

Does New Hampshire Electric Cooperative offer full 1 for 1 net metering credits for exported solar power

No, New Hampshire Electric Cooperative does not offer full 1 for 1 net metering. This means that when you export surplus power from your solar panels, you will be paid less by the utility than what you are charged to buy the equivalent amount of power from the grid.

The amount you are paid by the utility is known as a feed-in tariff. In the case of New Hampshire Electric Cooperative, this feed-in rate is $0.01 per kWh.

The rate NHEC pays for your excess power is about 25% of retail rates. 

What incentives, tax credits and rebates are available to NHEC customers for installing solar?

The major financial incentive currently available until the end of 2023 is the 30% federal solar tax credit. The way this works is that the full cost of the system needs to be paid to the installer, and this tax credit can then be claimed back as cash when you next do your taxes.

Many states, local governments and utilities also offer incentives for homeowners who go solar. This help can take the form of state tax credits, rebates, tax breaks, SRECs or even performance-based incentives. The best part is that all of these incentives apply in addition to the federal credit.

Here is every incentive you may be eligible for as a NHEC customer:

Residential Clean Energy Tax Credit (Federal) -$8,482
Local Option - Property Tax Exemption for Renewable Energy (State)

Cities have the option to exempt the cost of a solar system from property taxes. Not statewide.

Net Metering (State)

Utilities, except municipal, must offer net metering. Can offer full kWh credits on the bill or send customer check for avoided cost rate of excess kWh.
