What Is The Driver Of The Boiler Water Treatment Chemicals Market?

The increase in demand for power generation is expected to propel the growth of the boiler water treatment chemicals market going forward. Power generation installations refer to an industrial building that produces electricity using primary energy and one or more generators to transform mechanical energy into electrical energy. Chemical water treatment is essential for increasing the effectiveness of power generation in power plants and is critical for maintaining the stability of the functioning of thermal equipment. For instance, in June 2024, according to the International Hydropower Association (IHA), a UK-based non-profit, membership organization, in 2023, global installed hydropower capacity rose by 13.5 GW, bringing the total to 1,412 GW, with pumped‑storage hydropower (PSH) capacity increasing by 6.5 GW to 182 GW. Therefore, the increasing demand for power generation drives the boiler water treatment chemicals industry.
