Intro – ESS - Enabling Grid Stability in the Energy Transition

The global energy transition is accelerating:

  •  Wind & solar inverter capacity will grow ~3x in the next 5 years (IEA estimate)
  • Conventional power plants are declining, reducing synchronous generators that provide grid inertia
  • Grid stability challenges lead to fluctuating energy prices and higher blackout risks

Why ESS matters:

  • Energy Storage Systems (ESS) and grid-forming inverters are essential to maintain frequency stability, prevent outages, and integrate renewables
  • Therefore, ESS is surging with a projected 5 times increase in installations based on STEPS & NZE targets (IEA estimate), with the majority of new installation being Battery Energy Storge Systems (BESS)
  • Self optimization can reduce electricity bill cost for homes and commercial institutions, and utility scale installations with grid following or grid forming functions support grid stability and renewables energy integration
Infineon’s role

We drive system value and support system differentiation by focusing on power density, system cost saving and reliable subcomponents. We deliver a comprehensive portfolio for next-generation ESS:

Our expertise ensures efficiency, lifetime performance, and cost-effectiveness for a resilient, sustainable energy infrastructure.

Broad segmentation of ESS along the energy supply chain

Battery-based ESS technology can respond to power dropouts in under a second, making use of clean energy sourced from collocated solar or wind plants. In such before-the-meter cases, ESS functions as bulk storage coupled with either renewables generation or transmission and distribution systems. In residential and commercial situations, ESS plays a role as behind-the-meter.

Typical structure of energy storage systems

Energy storage systems are structured in two main parts. The power conversion system (PCS) handles AC/DC and DC/AC conversion, with energy flowing into the batteries to charge them or being converted from the battery storage into AC power and fed into the grid. Suitable power device solutions depend on the voltages supported and the power flowing.

The battery management system (BMS) handles cell charging, balancing, and health monitoring, complemented by a microcontroller providing system control and communication. Essential elements to integrate ESS into larger systems.
