Renewable Energy

Clean, renewable energy, like the privately-owned solar panels throughout Nashua, generate pollution-free electricity using a source that is in endless supply- the sun. Here we are looking at generation capacity – which is the maximum amount of electricity that could be produced by all of the solar panels in Nashua under perfect conditions.

Livable Nashua's Clean Energy Goals

Energy Manager Doria Brown talks through Nashua's big climate goals for clean energy and reducing GHGs.

Ever read your energy bill and gloss over a kilowatt hour?  Energy Manager Doria Brown breaks down how to think about what is a kilowatt is!

Hydro Power Production

Generating our Own

The energy we use to light, heat, and cool, our homes and businesses comes from different sources. Some of these sources, like oil and natural gas, pollute our environment and are in limited supply. Clean, renewable energy, like the City-owned hydro dams generate pollution-free electricity for Nashua that is readily available. Nashua now owns two hydro dams; Jackson Mills and Mine Falls (acquired in 2017).

UNIT
A megawatt hour (Mwh) is equal to 1,000 Kilowatt hours (Kwh). It is equal to 1,000 kilowatts of electricity used continuously for one hour. It is about equivalent to the amount of electricity used by about 330 homes during one hour.

Electricity Generation

The graph to the left shows the energy generation of Nashua's two hydro dams by quarter. Owning and keeping these assets generating as a community resource is one way that The City of Nashua is taking advantage of the resource that is the Nashua River and continuing the heritage of powering the community with it.

 

Solar in Nashua

Powered by the Sun

Clean, renewable energy, like the privately-owned solar panels throughout Nashua, generate pollution-free electricity using a source that is in endless supply- the sun. Here we are looking at generation capacity – which is the maximum amount of electricity that could be produced by all of the solar panels in Nashua under perfect conditions.

UNIT
Kilowatts measure power. For example, the capacity of a solar panel. Kilowatt hours show the amount of energy generated or used in a given amount of time. For example, the amount of power a solar panel generated over a year or the amount of energy used by a building over a year.

Solar Capacity

The solar generation capacity--or the amount of energy it is possible to generate--is increasing as we install more solar panels around the city

Solar Permits

2015 saw a peak for the number of solar permits pulled in Nashua. Let's keep the momentum going!

Solar on Schools!

Big solar projects are on the horizon for Nashua's public schools as we turn empty roof space into an asset for generating clean energy.

Teachers may not like smart phones in schools, but with the size of the solar project going in at Fairgrounds Middle School, you could charge over 69 million of them! Combined with the system planned for Dr Crisp Elementary, the schools will be producing the equivalent amount of energy as 140 single family households.

What's a Power Purchase Agreement?

A solar power purchase agreement, or solar PPA, allows schools, nonprofits and municipalities, who cannot take advantage of federal tax programs, to enjoy the same benefits of clean solar power afforded to businesses and homeowners – and ultimately own the system.

Working with Revision Energy, the School District will be able to install solar on both Dr Crisp Elementary and Fairgrounds Middle School with no up front costs and the option to buy the system after 25 years.  Even after purchasing the equipment, the District is slated to save over $1.87 million in energy costs over the life of the project.

What You Can Do!

Reducing energy use and transitioning to solar is something that can be done on the individual level, as well.


One way to increase the percentage of clean energy powering Nashua is to reduce the amount of electricity we need
