Asia-Pacific is expected to remain the largest combined heat and power (CHP) market in the world due to an increase in capacity installations, led by China, India and Japan, according to GlobalData.

The company’s latest report Combined Heat and Power Market, Update 2019– Global Market Size, Segmentation, Regulations, and Key Country Analysis to 2025 reveals that the global CHP capacity is estimated to grow significantly from 864.2GW in 2018 to 1,050.5GW in 2025, due to significant capacity additions by China and India.

Asia-Pacific (APAC) is the largest region in terms of both net capacity additions and cumulative CHP capacity in 2018.

“Europe was the region with the highest installed CHP capacity until 2009, primarily due to early development of technology, carbon savings target and large capacity installations in major countries such as Russia, Netherlands, Germany and the UK,” noted GlobalData’s power analyst, Anchal Agarwal.

Agarwal continued: “In 2010, the APAC region overtook Europe as it added capacities while Europe stagnated at its already high level.  The governments in APAC are strongly committed towards having a cleaner energy mix and are supporting the evolution of such technologies through various policies and R&D initiatives.”

Agarwal added: “CHP capacity in China increased significantly at a CAGR of 13% from 79.8 GW in 2006 to 347.6GW in 2018. The cumulative capacity increased especially during 2010–2013 and 2014–2017.

According to Agarwal, more than 90% of the total installed capacity is fed by coal.

During 2019–2025, the cumulative capacity of China is expected to increase from 363.3GW to 434.4 at a CAGR of 3.0%.

Gas-fired CHP systems

A specific rule calling for companies to switch off and replace coal-fired boilers prompted a number of companies to replace coal plants with gas-fired CHP systems.

China also plans to add over 12GW of biomass cogeneration capacity by 2020 and around 25GW biomass CHP capacity by 2035.

Auction-based competitive bidding has become a popular mechanism in recent years to drive CHP in most of the key markets. Read more: Global water meters market to be one-third smart by 2025

Countries including the UK, Germany and France have auction mechanism for various technologies including CHP.

Germany introduced its first regular CHP auction in December 2017, in which 82MW capacity was awarded at an average price of $46.10/ MWh.

Apart from regular CHP auctions, Germany also introduced innovative tenders to determine the role of CHP plants in decarbonising power and heat supply. 

The innovative tenders in Germany allocated 21MW in June 2018 and attracted three bids of 13MW in December 2018.

“The regulatory framework and policy structure supporting CHP in various regions and countries have led to significant development in the global CHP industry and have driven the leading CHP nations in growth trajectories. In the wake of growing energy security and environmental concerns, most countries are expected to strengthen their CHP support mechanisms, which will help the global CHP industry to maintain growth in the coming years,” Agarwal concluded.
