WGL Energy and Architect of the Capitol Complete 7.5MW Cogeneration System

Combined heat and power solution provides energy efficiency, cost savings and environmental benefits for Capitol Hill campus.


WGL Energy Systems, Inc. (WGL Energy) recently announced the completion of a 7.5 megawatt (MW) natural gas cogeneration system developed in partnership with the Architect of the Capitol. The new facility is designed to deliver a reliable, energy-efficient source that will save taxpayer dollars and reduce environmental impact, while providing steam to the 23 facilities served by the Capitol Power Plant, including national landmarks such as the U.S. Capitol, The Library of Congress and the Supreme Court of the United States.

Ayers, eleventh Architect of the Capitol; Tim Haines, Chief Operating Officer, WGL Energy Systems; Scott Clark and Ken Woodul of the Architect of the Capitol.

In 2015, the Architect of the Capitol, which runs the maintenance, operation, development and preservation of 18.4 million square feet of buildings on the Capitol campus and ensures these facilities meet current sustainability standards, awarded a Utility Energy Service Contract (UESC) to Washington Gas Light Company, an affiliate of WGL Energy, to perform the design, build and install of the cogeneration solution. WGL Energy served as the general contractor and project manager. 

The new system is part of a modern energy plan initiated by the Architect of the Capitol to add proven cogeneration energy technology, also known as combined heat and power (CHP), at the Capitol Power Plant. The Capitol Power Plant’s cogeneration system, delivered by WGL Energy, uses natural gas in a combustion turbine, enabling the Architect of the Capitol to generate its own electricity and heat, as well as deliver a reliable source of chilled water and steam, to improve system reliability and self-sufficiency and support energy cost savings across the properties it manages. 

“WGL Energy is proud to create an innovative energy system in collaboration with the Architect of the Capitol that showcases what investment in an efficient and environmentally-friendly energy technology solution can do to benefit the city and surrounding community,” said Adrian Chapman, President and CEO of WGL Holdings, Inc., parent company of WGL Energy. “We are honored to have called the District of Columbia home for 170 years and we look forward to continue providing diverse energy solutions to customers in the DC-area that lead to a clean and sustainable energy future.” 

“We have set a goal here at the Architect of the Capitol of a 50 percent reduction in our energy use intensity over our 2003 baseline, and as we mapped out how we are going to reach that goal, this cogeneration project is the single biggest contributor to our success,” said Architect of the Capitol Stephen T. Ayers, FAIA, LEED AP. 

During each phase of construction and implementation, experienced project partners contributed time, expertise and talent, including primary subcontractor and Engineer of Record Burns & McDonnell, and local-area contractors RMF Engineering, Marchuk Construction Company and Atlantic Constructors (ACI). WGL Energy has more than 300 megawatts (MW) of distributed generation projects installed or under contract across 20 states and the District of Columbia.

More Price Volatility

Week in review for November 25 - December 1, 2018


On Thursday, the U.S. Energy Information Administration (EIA) reported that working gas in storage as of Friday November 23, 2018 was 3,054 BCF.

Storage levels are now 372 BCF lower than the previous 5-year low. 

This week, the NYMEX natural gas 12-month strip (Cal 2019) was up 2.0%, while the PJM West Hub Cal 2019 strip fell 1.3%. Prices for January through March 2019 remain highly volatile. Natural gas prices further out in 2020 and beyond remain near all-time lows.

Giving Back

WGL Energy Partners with Children’s National to Light Up the DMV through ‘Light Up Dr. Bear’ Fundraising Campaign

Innovative holiday campaign encourages community giving and brings joy to patients and their families.

This holiday season, WGL Energy Services, Inc. (WGL Energy) will serve as the exclusive campaign ‘matching partner’ of the Light Up Dr. Bear campaign launched by Children’s National, the largest and most comprehensive pediatric hospital in the mid-Atlantic.
The innovative fundraising campaign features special ‘light up bears’ that illuminate with bright colors when a donation is made using text or online giving options. The bears, tailor-made to resemble the hospital’s iconic Dr. Bear mascot, will be placed in local communities in D.C., Maryland and Virginia, and within Children’s National’s main campus and outpatient clinics.

In total, 316 bears are displayed across the D.C. region, one for each bed in the Children’s National main hospital. The bears come in 4-foot and 12-inch versions and are accompanied by step-by-step instructions on how to make a gift using text-to-donate technology. Bears are positioned in the hospital at nursing stations, in the cafeteria, and in its Costco Wholesale Atrium so the thousands of people who walk through the Children’s National halls every day can witness the bears shine with each donation and reflect on the generous spirit they represent.


Be sure to share your photos of Dr. Bear on Facebook, Instagram and Twitter with #LightUpDrBear and follow us @wglenergy.com on Twitter.


You can show you care and light up Dr. Bear, by making your donation today to childrensnational.org/light.

*Cooling degree days reflect the Washington, D.C. area and are calculated by comparing the day’s average temperature to a 65 degree baseline.  If the day’s average temperature is below 65, there are no cooling degree days that day.  If the average temperature is greater than 65 degrees, then subtract 65 from the average temperature to find the number of cooling degree days.
