Description
According to a research report published by Transpire Insight, the air-cooling synchronous condenser market size is projected to grow from USD 845.6 billion in 2026 to USD 1135.2 billion by 2035, at a CAGR of 4.5% during the forecast period 2027-2035. When fossil fuel plants are phased out, they remove grid inertia. Air-cooled synchronous condensers are used to supply the required reactive power, short-circuit strength, and voltage regulation without the use of precious water.
Introduction
As power grids come to include more intermittent solar and wind power, the air-cooling synchronous condenser market is growing rapidly. Passive inertia traditionally was achieved by spinning generators on fossil-fuel plants, and with their retirement, power system stability is reduced. Clean, water-free rotational inertia and dynamic reactive power from air-cooled synchronous condensers. The technology is invaluable for grid stabilization, remote renewable installations, and to avert blackouts in dry regions all over the world.

Regional Growth and Demand Analysis by Transpire Insight
North America remains the growth driver for demand, with utilities in the U.S. and Canada looking to upgrade their grid-support equipment fleet as they upgrade their aging thermal generation plants. Investment in upgrading and expanding transmission infrastructure and a movement toward minimizing water use are directing utilities toward air-cooled designs rather than water-cooled designs. GE and ABB have been among the players to advance static-frequency-converter (SFC) synchronous condenser solutions for enhanced voltage stability in areas where wind and solar power is prevalent, and regulatory focus on energy-efficient, low-maintenance systems is facilitating that change. Japan is next, with substantial investment in flexible AC transmission systems for parts of the Baltic region and grid-stabilization projects closely following suit in Europe, led by Germany, France and Italy.
An unprecedented level of grid expansion in China and India's target to reach 500 GW of non-fossil fuel electricity capacity is driving growth in Asia-Pacific. Similar efforts are found in South Korea and Japan, where investments in modernization and integration of offshore wind are driving utilities to scale up their use of reactive power support. New and remanufactured condenser opportunities are growing with Southeast Asian government-supported grid-interconnection programs, and regional players like Mitsubishi Electric and Toshiba Energy Systems are stoking growth in their condenser portfolios to satisfy both the demand of the utility and industrial sectors.
