As with any project, the construction phase was not without some unforeseen conditions and further analysis was necessary. For example, during construction, items were discovered from the ground which needed further investigation by a licensed archeologist. Thus, the project timeline was reevaluated and adjusted. Construction on the first host site started in July 2018 and the system went fully operational in March 2019.
In the final configuration, the system consists of three solar carport sites totaling 9920 PV panels with system sizes of approximately 1,692 kW, 2,797 kW and 174 kW, and one solar groundmount site of 5000 PV panels and a system size of 2,350 kW. The system total annual production capability is 9,528,550 kWh, and total monthly production of 794,045kWh. Production term for the system is 25 years and there is a 26-year lease term at appraised fair market rental value. The cost analysis of the project accounts for a 0.25%/year degradation rate.
The presentation and tour of the sites was given by Mr. Keith Benson, Director, Energy and Engineering, Navy Installations Command, Mr. Chris Cimento, Utilities Infrastructure Manager, NAVFAC Washington, and Ms. Paula Teague, Resiliency and Renewable Energy Branch Supervisor, NAVFAC Engineering Command Atlantic. Ms. Giuliana Kunkel, Account Manager, also presented for the DC Sustainable Energy Utility.
Recently, Joint Base Anacostia-Bolling (JBAB) hosted the Association of Energy Engineers (AEE), National Capital Chapter (NCC) for a presentation and a tour of the newly installed solar carports and groundmounts.
The solar project at JBAB is the largest commercial PPA in-stalled within the District of Columbia, at a maximum system capacity of 7 MW, and it is comprised of three carport sites and one groundmount site. It was developed by the Department of the Navy, with collaboration across various internal departments, federal partners through the Department of Defense, Department of Energy and the National Renewable Energy Laboratory, DC Sustainable Energy Utility, and the private sector. No easy feat! Coordinating this many partners took a lot of analysis, planning, and grit.
Pursuant to the Energy Policy Act 2005, EO 13423, EO 13693 and Navy policy, the Navy explored opportunities to integrate onsite renewable energy with the goal of becoming more resilient and cost effective. However, it is a long and challenging path to travel from policy to reality. Much of the successful completion of this solar project is attributed to the careful planning and in-depth analysis done during the investigative phase of the project. Initial groundwork done consisted of a memorandum of understanding with the Department of Energy and NREL; approvals obtained from the Secretary of Defense and the White House; initial screening of potential sites; initial assessment of potential system size; tenant town hall meetings; ICO approval; technical studies for glint-glare, electrical, rooftop and other needs or requirements; site approval for each site ICW installation appearance plan and master plan.
The request for proposal, inclusive of technical studies, was released in June 2015 with the help of the DC Sustainable Energy Utility. Contractors selected preferred sites and proposed a variety of solutions. The PPA was awarded to Sun Power in December 2016. The project was developed as a model 3 type, meaning 100% on-site solar production and 100% on-site consumption. Careful analysis was done in order to evaluate the existing power grid and ensure the installation
It is impressive to see what determination, focus and dedication can accomplish. The solar system currently operational at JBAB stands as the largest residential system built in DC. The National Chapter was extremely impressed by the amplitude of the system and by the graciousness and generosity of our Navy hosts. Thank you! Go JBAB!
For the history buffs and perhaps not-so buffs, JBAB was established in 2010 under BRAC as a Navy-led joint base. It covers 905 acres of land along the Anacostia River in Washington DC and houses a variety of best in class tenants such as the Air Force Honor Guard and the Air Force Band, DoD Commands and White House Communications Agency. The base has a rich history of tradition and service, which I encourage you to read more about at: https://www.cnic.navy.mil/regions/ndw/installa-tions/jbab/about/history.html.
of the new system would not produce overload of the grid. None of the power produced in this system is slated for export, everything is consumed onsite.
