Reducing Energy Hero Image


One of the cornerstones of Raytheon’s sustainability initiative is our energy management program. We advance our sustainability vision by conserving our planet’s natural resources and by reducing energy-related greenhouse gas emissions and other pollutants. Managing our energy resources also makes us more cost competitive.

Energy comsumption chart

Between 2008 and 2015, we reduced our U.S. energy consumption by 18 percent, saving more than 3,350 billion BTUs cumulatively. Since then, we have cut energy use by an additional 3.3 percent. Our integrated energy management strategy spans our buildings, manufacturing processes, information technology, engineering design and communications. In 2018, we executed on projects that reduce energy consumption by 14,000 MMBtu annually. Specifically, we upgraded chillers, boilers and central plants, converted lighting to LEDs, upgraded building management systems and expanded our Smart Campus program.



I applaud the 2019 ENERGY STAR Award Winners. Their innovation and leadership enhance America’s economic competitiveness. Reducing costly energy waste improves air quality and public health while protecting the environment.

Integrating energy efficiency into building designs

For more than 19 years, Raytheon has been a partner in ENERGY STAR®, a voluntary U.S. EPA program that promotes strategic energy management. For the 12th consecutive year, the U.S. EPA awarded Raytheon its ENERGY STAR® Partner of the Year — Sustained Excellence Award for our leadership in protecting the environment through superior energy efficiency accomplishments.

The award acknowledges our continuous commitment to energy management and our strong energy programs and initiatives. Raytheon’s business grew significantly in 2018, and this expansion means new requirements — and new facilities and space to support them.

  • Use energy-efficient design and construction in new or modified spaces
  • Pursue Leadership in Energy and Environmental Design (LEED) certifications and incorporate LEED practices
  • Design and construct buildings to exceed ASHRAE 90.1 standards — Energy Standard for Buildings
  • Integrate the latest smart technologies during building modernization
  • Improve and standardize data center design

For all new buildings, we specify envelope insulation and LED lighting to drive improvement over the ASHRAE 90.1 baseline. In 2018, we opened a new standardized data center at our Tucson, Arizona, site. This new stand-alone building, which is designed specifically and only for use as a data center, utilizes a rack-mounted rear-door cooling system with chilled water and variable-speed fans to efficiently cool the computer equipment. This, along with the utilization of hydronic-free cooling and fault detection and diagnostic software, enables the data center to operate with a power usage effectiveness (PUE) of 1.5. A second, larger data center is currently under construction at the same site, using the same design standards.

Additional energy projects include switching to energy-efficient LED lighting; installing state-of-the art building automation systems; upgrading central plant facilities; making improvements to compressed air systems, lab areas and production equipment; and implementing Smart Campus technologies.



Raytheon uses data centers to store and process key information such as the electronic models used to design, manufacture and support our products, enterprise resource planning and the company’s financial systems. Because these data centers consume large amounts of energy, Raytheon kicked off an initiative in 2016 to deploy advanced energy management techniques at our four major enterprise data centers to reduce energy use, save energy costs and eliminate waste.

We partnered with third-party resources to complete a number of improvements. We implemented a system that centralizes information management for all enterprise data centers and also developed new processes that leverage the capability to optimize our allocation of computers, storage and backup hardware. Additionally, we deployed automatic software processes that manage the way we use memory and storage, identify zombie servers and manage CPU spikes. We also used Raytheon Six Sigma™ tools to simplify operations, increase utilization and speed automation. Specifically, we optimized settings of virtual high-availability servers to reduce waste and implemented dynamic storage provisioning that reduces hardware requirements and energy use.



Renewable energy, or green power, is energy produced from renewable resources including solar, wind, geothermal, biogas and low-impact hydropower. Green power resources help protect human health and the environment by producing electricity without generating fossil fuel- based greenhouse gas emissions and other forms of air pollution.



Raytheon has been supporting the renewable energy market for the last 12 years. We’ve bought or generated more than 300 million kilowatt-hours of renewable energy at many different Raytheon sites, including Tucson, Arizona; Aurora, Colorado; Indianapolis, Indiana; Andover and Tewksbury, Massachusetts; McKinney and Dallas, Texas; and Dulles, Virginia.

Between 2007 and 2018, our use of renewable energy has reduced greenhouse gas emissions by a cumulative 208,500 metric tons of carbon dioxide equivalents. This equates to the greenhouse gas emissions reduction from removing 44,268 cars from the road for a year.

Andover solar project

Raytheon has three on-site solar projects. We installed the first project, a 100-kilowatt system, on the roof of a large building at our Andover facility in 2008. It has operated continuously through many storms with high winds, snow and rain. The other two solar projects are ground-mounted solar panel systems located on the U.S. Air Force Plant 44 at Raytheon’s Tucson site. Through collaboration with the Air Force, a 55-kilowatt photovoltaic system was developed that converts sunlight directly into electricity to help power the site. The systems were installed and placed into service in 2012.

Located on a former U.S. Navy manufacturing site that opened in 1942, the nearly one-million-square-foot facility in Indiana draws from an energy grid that uses coal — the dirtiest burning fuel — to generate roughly 50 percent of its electricity.



Our 2020 renewable energy goal is to buy or generate 5 percent of the electricity we use from renewable sources. In 2018, we continued to make good progress toward the goal, and ended the year at 4 percent renewable energy. This renewable energy came from our three on-site solar projects in Tucson and Andover, plus renewable energy from various wind farm projects in the Midwest and around the nation.

Solar net metering project in Spencer, Massachusetts

Raytheon is also supporting off-site renewable energy projects that add 9 megawatts of capacity to the Massachusetts power grid. In 2017, we entered into multiple 20-year “solar net metering” contracts in which Raytheon agreed to purchase a large amount of solar electricity without taking the renewable energy certificates. The largest of these projects is located at the 200-acre St. Joseph’s Abbey property in Spencer, which hosts one of the nation’s largest community solar projects. Raytheon’s long-term financial commitment, combined with support from local communities, makes this and many other community solar projects possible.

Raytheon has been a partner in the U.S. EPA’s Green Power Partnership program for many years. The program encourages organizations to use green power to mitigate the environmental impacts of conventional electricity. More than 1,700 partner organizations are voluntarily using more than 45 billion kilowatt-hours of green power annually. In 2018, Raytheon ranked in the top 50 on the Fortune 500 Partners List for the seventh consecutive year.
