Tender Notice

(Tender number: T231100111490)

1. Tendering conditions

The bidding project, the design and construction general contracting of the 200MW/1000MWh all-vanadium liquid flow energy storage project of Three Gorges Energy Xinjiang Jimusar, has been approved for construction. The construction funds come from self-owned funds and self-raised funds. The bidder is Three Gorges New Energy Jimusar Power Generation Co., Ltd., and the bidding agency is Three Gorges International Tendering Co., Ltd. The project has met the bidding conditions and is now open for bidding for the construction of the project.

2. Project Overview and Bidding Scope

2.1 Project Overview

The Three Gorges Energy Xinjiang Jimusar Solar Storage Project 200MW/1000MWh All-vanadium Liquid Flow Energy Storage Power Station Project is located about 11km northwest of Jimusar County, Changji Prefecture, Xinjiang, and about 6km northwest of Beiting Town. The west and north sides of the site are close to existing rural roads, the south side is about 1km away from Y385 Township Road, and about 5.5km away from X183 County Road, with very convenient transportation.

This project plans to build a 200MW/1000MWh all-vanadium liquid flow energy storage system, which is mainly composed of all-vanadium liquid flow electrolyte, storage tanks, stacks, thermal management systems, circulation systems, battery management systems (BMS), energy management systems (EMS), self-use power systems, distribution equipment, converters (PCS) and step-up transformers, supporting auxiliary facilities and equipment, and construction projects. Among them: 1# energy storage power station will build a 150MW/750MWh all-vanadium liquid flow energy storage system, which will be connected to the 35kV side bus of the proposed 1# 220kV step-up collection station with 6 35kV collector lines. 2# energy storage power station 50MW/250MWh all-vanadium liquid flow energy storage system, which will be connected to the 35kV side bus of the proposed 2# 220kV step-up collection station with 2 35kV collector lines. (The access system plan is subject to the final access system review opinion).

2.2 Scope of Bidding
