Key Market Insights

10 kV to 69 kV segment held over one-third of global market share in 2023.

Industrial application accounted for more than 25% of revenue in 2023.

Star connection type dominated with a CAGR of 5.0%.

Asia-Pacific led the market, capturing more than one-third of revenue in 2023.

Market Overview

A capacitor bank is designed to store and release electrical energy as needed, primarily enhancing power factor correction (PFC) in electrical networks. A low power factor can lead to excessive reactive power, increasing operational costs and energy losses. Capacitor banks compensate for this reactive power, ensuring energy efficiency and stable voltage levels.

One of the key applications is in power distribution systems, where capacitor banks help regulate voltage, reduce transmission losses, and maintain consistent electricity supply. Industries like data centers, hospitals, and automation-driven manufacturing rely heavily on capacitor banks to avoid voltage fluctuations that can cause costly downtime.

Market Dynamics

Growth Driver – Renewable Energy Integration

The rapid integration of renewable energy sources such as wind and solar is a primary driver for the capacitor bank market. Renewable sources are intermittent, causing fluctuations in power generation. Capacitor banks enable grid operators to manage these fluctuations, ensuring voltage stability and efficiency.

For instance, in 2024, Australia’s Clean Energy Finance Corporation (CEFC) allocated over one-third of its $1 billion Household Energy Upgrades Fund to projects like capacitor bank installations to support renewable energy systems. Similarly, Larsen & Toubro's Digital Energy Solutions expanded globally with advanced hybrid energy management systems, integrating capacitor banks to stabilize hybrid power plants.

Market Restraint – Alternative Technologies

The rise of Static VAR Compensators (SVCs) and Static Synchronous Compensators (STATCOMs) is challenging traditional capacitor banks. These advanced technologies offer faster response times, real-time voltage regulation, and adaptability to fluctuating power demands. For example, in 2023, POWERGRID installed a ±300 MVAR STATCOM at Lucknow Substation, enhancing reactive power compensation in India’s grid.
