Willdan Expands Power Delivery Engineering Capabilities With KCS Corporation

Key Terms

power delivery engineering technical

Power delivery engineering is the discipline that designs and manages the electrical systems that carry energy from sources (like grids, batteries, or generators) to the devices and equipment that use it. It matters to investors because these designs affect reliability, efficiency, cost and safety of products and infrastructure—similar to how a city’s road network affects traffic flow, the quality of power delivery determines operating performance, maintenance needs and capital expenses for energy-dependent businesses.

battery storage technical

Battery storage is a system that stores electricity in large rechargeable batteries so power can be used later, like a reusable fuel tank for the grid. Investors care because it smooths out when energy is available vs. when it’s needed, can lower costs, create new revenue from selling stored power at peak times, and reduce reliance on unpredictable energy sources, affecting utility and clean-energy company valuations.

grid modernization technical

Grid modernization involves upgrading the electrical system to make it more reliable, efficient, and capable of handling new technologies. It often includes integrating advanced digital tools, better communication systems, and renewable energy sources. For investors, these improvements can lead to more stable energy supplies and open opportunities in emerging energy markets and technologies.

substation technical

A substation is a fenced facility on the electricity network where equipment changes the voltage, routes power, and protects the grid so electricity can move safely and reliably from generation to homes and businesses. Investors care because substations are critical pieces of infrastructure: they affect service reliability, grid capacity and upgrade costs, and can influence the value and operating risk of utilities, real estate near outages, and companies in the energy supply chain.
