RALCO Electric is an authorized generator sales and services of:

Cummins Onan, Kohler and Briggs & Stratton


The Potter League, an animal shelter in Middletown, R.I., became the first shelter in the U.S. to earn LEED Gold certification by the U.S. Green Building Council (USBGC).

Using an innovative array of sustainable features from a rooftop garden to rainwater cisterns, the $8 million building is an example of a holistic view on animal welfare and resource conservation. Not only is the Potter League the first animal shelter to gain LEED Gold certification, but it is also the first building in Rhode Island to receive LEED Gold. Some of the green features of the new building include:

Plastic wainscoting made from soda and milk bottles

  • A floor made from recycled tires
  • Use of highly renewable radiata pine and bamboo
  • A storm water management system that captures 90 percent of storm water through a 15,000 gallon cistern, utilizing a permeable paved parking lot to absorb runoff. The water will be reused to flush toilets and clean animals’ cages.
  • Landscaping with native plant species including a vegetated rooftop
  • Low-flow toilets and faucets
  • A focus on utilizing natural lighting

The project was also recognized for recycling more than 75 percent of construction materials and demolition waste.

RALCO provided all electrical services through Behan Bros, Inc., the general contractor on the project.

Generator Sales & Services Commercial

Cummins Onan – Kohler – Also: Mobile and Marine Generators

Businesses can ill afford downtime in these days of instant communications, instant delivery of products and services and global competition. An ecommerce site down for just a few hours may lose millions of dollars in sales. Manufacturing companies may put a contract at risk when their shops grind to a halt. Mission critical services such as healthcare providers, data centers and telecommunication companies endanger not only their own services but those of their clients the minute they go dark. In each of these cases, a standby commercial generator will keep the business running – at full power – until the local utility restores service.

At RALCO, we’ve been working for over 25 years with businesses in all industries to help prevent downtime due to power outages. Whether you choose a Kohler or a Cummins Onan generator, you’ll be assured of business continuity during power outages of all durations.

As your local sales and services provder, we offer planned maintenance agreements that keep your generator in top running condition.

Solar and Wind Power

The time has finally come when power solutions such as solar panels and wind turbines are a strong complement, and alternative even, to the electric grid or gas supply. In the state of Massachusetts alone, recently enacted green energy policies that promote green buildings and green communities make grants and subsidies to commercial and municipal projects. Residential alternative power installations are also eligible for energy grants. In addition to these funding sources, the net metering option makes it possible for owners of wind turbines and solar-generated power to sell their excess electricity into the grid (net-metering) at favorable rates for installations of up to 2 megawatts.

RALCO Electric’s Solar and Power division offers comprehensive services for the installation of alternative power solutions, including sales, installation and maintenance of solar panels and wind turbines.

Let our knowledgeable staff help you with your green power solutions.

Solar Panels

The State of Massachusetts has set an ambitious goal to achieve 250 MW of solar power installations by 2017, and in support of that goal has established a number of incentive programs available to businesses and homeowners alike. The Commonwealth Solar II Rebate Program provides rebates based on the size and other characteristics of the project.  Part of our project management for your installation includes assisting you in applying for such rebates.

The sun’s energy is collected through a number of technologies: passive solar and solar thermal to heat air and hot water, and photovoltaics to generate electricity.

Solar Thermal – Active solar thermal systems collect solar radiation to heat air and/or water for commercial, industrial or residential use. A pump in a solar hot water collector circulates the water which is warmed up and used to provide heat or hot water to the building. There are many types of solar water heaters on the market and  RALCO will guide you to the most suitable selection for your building

Passive Solar – The absorption of sunlight through south-facing windows, using dark-colored, dense material refers to passive solar design. Passive solar design techniques are most easily applied when designing a new building to collect, store and distribute solar energy as heat.

Solar Voltaic – A solar photovoltaic module is an array of cells containing semiconductor materials that convert solar radiation into direct current electricity. Installations that include a solar PV system connected to the power grid will feed any excess electricity it produces into the grid and credited on your electricity account. Over the last 10 years, the installed cost of solar PV has dropped 30%. Contact RALCO to evaluate your options.

Wind Turbines

The Commonwealth’s goal is to install 2000 megawatts of wind energy by 2020 and to reach that goal, the State is providing a number of incentives for various size projects: community scale, microwind and commercial wind.

Consider these numbers: a single 1 MW turbine on land can provide enough electricity to power 225 to 300 households. A single 1 MW turbine in an offshore wind farm, where the wind blows harder and more consistently, can power more than 400 households.

Wind turbines are surprisingly quiet, considering they are large, rotating structures. Noise impacts are regulated by municipalities as well as the Massachusetts Department of Environmental Protection (MassDEP), and should not be a factor for wind projects.

Residential wind turbines

If you did not think about wind turbines as an alternative energy solution, think again. Roof-top wind turbines and pole-mounted turbines have come on the market and offer very quiet and safe options.

We are a licensed electrical contractor in the states of MA, RI, NH, VT and ME.
