Grid Energy has supported a three year medium voltage campus grid modernization effort on Georgetown University’s historic campus in Washington, DC. As part of this effort, Grid Energy assisted the University in evaluating different ways to use chemical energy storage to provide voltage support and resilience to sensitive grant funded research programs and global IT functions at a systemic level.
Grid Energy led an effort to analyze the impact of unscheduled feeder switching and other voltage irregularities and to design solutions that employed a combination of solid state switching, supercapacitors, and lithium ion energy storage to create a designated medium voltage feeder loop for critical operations.
As part of this effort, Grid Energy conducted electrical interval data analysis at a building and subbuilding/bus level and modeled a variety of scenarios for maintaining continuity of operations by providing voltage support within two cycles of electricity. Grid Energy led electrical engineering and design work for the interconnection, islanding, and operations of the energy storage system and selected equipment manufacturers and products for system. Grid Energy also selected civil works construction firms and operations and maintenance and warranty providers for the system.
Grid Energy supported University leadership and stakeholders on the sustainability benefits of the system and on the architecture of the energy storage system as the foundation for a larger campus microgrid.
The effort proposed a variety of different ways in which the University could use different sized energy storage systems to optimize across a number of different scenarios, to include economic benefit, sustainability plan objectives, islanding and resilience, distribution system support functions, and wholesale market operations.
As part of this initiative, Grid Energy led an engagement strategy with the District of Columbia Public Service Commission inside its Case 1130 MEDSIS Grid Modernization program, positioning the University as a stakeholder contributing to modernization objectives and eligible for grant co-financing.
Grid Energy additionally developed third party financing options for build/transfer, acquire/operate, and build/own/operate turnkey solutions for the University to evaluate ways to reduce balance sheet impact and operational risk and responsibility, as well as leverage capital markets to avoid IRR hurdles and reduce opportunity cost for other internal investment strategies.
