On September 17, the Hami Yizhou District 100MW/400MWh LFP and sodium-ion grid-forming independent energy storage project of Yanyang Zhichu terminated its EPC turnkey tender. Per the termination notice cited in Century Energy Storage's daily tender report published on September 18: the project's investment price cap was estimated on the basis of installed capacity and capacity-pricing coefficients; to implement investment cost controls more precisely and optimize project estimation, the EPC investment-cost benchmark indicators require systematic review and adjustment; and because the benchmark stated in the original tender documents must be updated in tandem, the tenderer decided to terminate this tender to safeguard the rigor and compliance of bid price evaluation and the stability of later construction, contract performance and settlement, and to mitigate tendering and audit risks. The termination came before the original bid submission deadline of 00:09 on September 21, 2026.
For project background: the EPC tender notice was issued on August 31 (tender No. SDHHHTZB-26-08-027), with Hami Yanyang Zhichu New Energy Co., Ltd. As the tenderer, located in Hami, Xinjiang. The total installed capacity is 100MW/400MWh on a hybrid route: a 90MW/360MWh LFP battery system plus a 10MW/40MWh sodium-ion battery system, built on the grid side mainly for frequency regulation and peak shaving with grid-forming control technology. A 10% sodium-ion capacity share in a grid-side grid-forming independent storage project makes this one of the representative 'LFP + sodium-ion' hybrid storage tenders in Xinjiang.
A tender termination does not mean the project is cancelled, and no re-tender timetable has been disclosed; the 10MW/40MWh figure is the tender configuration, not a final construction scale; the CNY 440 million self-raised funds and CNY 1.1/Wh are funding estimates, not any winning price.
