TKDA Drives Resilient Design with a Microgrid‑Enabled Maintenance Facility

TKDA is proud to partner with the City of Porterville to design a forward‑looking maintenance facility that supports the City’s transition to a zero‑emission fleet. The new 25,000‑SF facility is being thoughtfully planned to meet the City’s operational needs, including maintenance bays, parking, office areas, and breakrooms, while providing the flexibility to service both traditional and electric vehicles during the City’s phased conversion to a zero‑emission fleet by 2040.

To enhance resilience and support the City’s long‑term sustainability goals, the facility will be connected to the City’s microgrid. A microgrid is a localized energy system capable of generating, storing, and distributing electricity independently or while tied to the main utility grid. Microgrids are increasingly used to improve sustainability, manage energy costs, support electrification, and advance decarbonization initiatives. 

While microgrids often help manage peak loads, this facility’s connection is being driven primarily by the need for operational continuity. During storms, natural disasters, grid failures, or brownouts, the microgrid will provide uninterrupted power by utilizing multiple potential energy sources, such as photovoltaics, battery storage, combined heat and power, or generator systems. This will allow essential operations at the maintenance facility to continue even when the broader grid is under stress, reflecting citywide efforts to strengthen resilience against energy disruptions.

TKDA helps cities like Porterville lead the advancement of energy‑resilient and sustainable infrastructure. Through innovative facility design and strategic energy integration, we are committed to delivering solutions that support our clients’ sustainability, electrification, and long‑term operational goals.
