Molten-Salt Storage Retrofit: A Chinese Maker Wins the Pump Package for a 50 MW/100 MWh Coal-Plant Conversion
Jiangsu Feiyue Pump Industry has won the molten-salt pump package for a 50 MW/100 MWh electric-heated molten-salt storage system being retrofitted at a 2×300 MW coal plant in Baotou — a project built to decouple steam supply from power dispatch.
Lead
Jiangsu Feiyue Pump Industry Co. (江苏飞跃泵业股份有限公司) has been named the winning bidder for the molten-salt pump procurement of a molten-salt thermal storage retrofit at the Baotou No. 1 Thermal Power Plant in Inner Mongolia, according to a procurement result notice published on 21 September 2026.
Facts
The award. The notice was published by Yantai Longyuan Power Technology Co. (烟台龙源电力技术股份有限公司) for the project formally described as a frequency-regulation, peak-shaving and safe steam-supply retrofit based on molten-salt thermal storage at the Baotou No. 1 plant of North United Power Co. (北方联合电力有限责任公司包头第一热电厂). (Sources: ESPlaza (长时储能网), 2026-09-22; the national solar thermal energy industry alliance's member bulletin, 2026-09-22.)
The plant. The Baotou No. 1 plant, in the city's Jiuyuan district, operates two 300 MW subcritical coal-fired units and supplies industrial steam at 1.8 MPa and 300 °C, with an average extraction of about 140 tonnes per hour and demand described as still growing. (Source: ESPlaza.)
The problem the retrofit addresses. The plant's account, as carried in the notice coverage, names three constraints: limited deep peak-shaving capability, insufficient frequency-regulation and peak-topping capacity, and a failed start-up boiler. The retrofit is intended to decouple heat from electricity, raise flexibility and secure the steam supply. (Source: the same.)
The system being built. A 50 MW/100 MWh electric-heated molten-salt storage system inside the plant boundary, with dual power feeds taken from the two units' isolated-phase busbars through two additional 63 MVA transformers, plus a 15 MW standby feed. The two units share one molten-salt-to-steam/water heat exchanger rated at 70 tonnes of steam per hour at 1.8 MPa and 300 °C. (Source: the same.)
The maker. The alliance's bulletin identifies the winner as one of its council-member companies. The pump package covers the machines that circulate molten salt between the storage tanks and the heat exchanger — the duty that ties the storage system to the steam side.
