What Kaishan Group does

Kaishan Group (开山控股集团股份有限公司, Shenzhen: 300257) is a Quzhou-headquartered, publicly listed Chinese industrial conglomerate founded in 1956 that has evolved from a rock-drill and compressor manufacturer into a diversified global equipment producer and geothermal energy developer. Its core product portfolio spans screw air compressors (fixed and mobile, single-stage and two-stage, oil-injected and oil-free), scroll compressors, centrifugal compressors, oil-injected screw vacuum pumps, process gas compressors, refrigeration systems, blowers, and a heavy-machinery line of hydraulic open-pit drills, deep-hole drills, tunneling drills, scaling rigs, anchor drills, and intelligent rock drilling robots. The technology foundation is built around screw airend and expander engineering, including proprietary Y-type and Dr. Tang patent rotor profiles, ORC axial turbine expanders (93.8% isentropic efficiency), and a patented 'one-well-one-station' (一井一站) modular geothermal concept that lifts well thermal efficiency from 8-12% (traditional centralized plants) to 18-19%. Manufacturing is conducted across wholly-owned plants in Quzhou and Shanghai (China), Loxley, Alabama (KCA, with the new TPS factory under construction), Leobersdorf, Austria (LMF, acquired 2016), and Izmir, Turkey (KCT, inaugurated June 2026), with sales/service centers in Melbourne, Warsaw, Mumbai, Dubai, Ho Chi Minh, Taichung, and Hong Kong.

Revenue is generated through a hybrid model: (a) B2B hardware sales of compressors, expanders, and drilling equipment via direct field sales and an over-600-dealer network in China and neighboring markets; (b) EPC and modular equipment supply for geothermal power projects; and (c) long-duration managed-services revenue from owned-and-operated geothermal power plants in Indonesia (SMGP 240 MW), Kenya (Menengai Sosian/OrPower22/KK01 at 35 MW each, plus Olkaria 165 MW in build), USA (Star Peak, Whitegrass, Fish Lake, Bottle Rock, Wabuska), Hungary (Turawell/Tura), and Turkey (Gülpınar JV). Customers include state-owned utilities (PLN, KenGen, KPLC), California Community Choice Aggregators (CC Power, MCE, PCE, SCPPA) under 20-25 year PPAs, and large industrial groups in steel/metallurgy (Baosteel/WISCO, Hebei Steel, 钢研氢冶金) for hydrogen metallurgy compression. Diversification is accelerating into green ammonia and green fertilizer production (Kenya Olkaria USD 800M project, 200,000 t/yr ammonia + 480,000+ t/yr fertilizer) and hydrogen dry screw compressors for industrial-scale green H2 applications. Multilateral lenders (IFC, African Development Bank, China Exim Bank) provide project finance for overseas geothermal assets.
