1. Open Tender

1.1 Tender Conditions

The name of this tender project is the open tender for the energy storage system of the 100MW agricultural photovoltaic complementary power generation project. The project tender number is CEZB250603638, with the tenderer being Guoneng Hudian (Shanghai) Engineering Technology Co., Ltd. The project is financed through self-funding. The tendering agency is the International Engineering Consulting Company of the National Energy Group. This project meets the tendering conditions and is open for domestic qualification review.

1.2 Project Overview and Tender Scope

The project is located in Yangjiang Town, Qionghai City, which is situated in eastern Hainan Province, bordered by the South China Sea to the east, Wenchang and Ding’an to the north, Tunchang and Qiongzhong to the west, and Wanning to the south. The area covers approximately 3,240.8 square kilometers. Qionghai City has a tropical maritime monsoon climate with an average temperature of 24.8°C. The center coordinates of the project are 110.3335°E longitude and 19.04897°N latitude, covering an area of about 1950 acres. The primary vegetation consists of betel nut and banana trees.

The region experiences a long annual sunshine duration of over 2,000 hours and an average annual temperature of 24.9°C, with the highest average temperature around 29.3°C and the lowest around 20°C. The average annual precipitation is 1,664 millimeters with more than 150 rainy days each year. The predominant winds are southeast and east, with an average annual wind speed of 3.4 m/s.

The project site is in an area prone to typhoons; statistics show that Qionghai has experienced 17 typhoons, with two of them rated at level 14 or above. According to the 2022 Basic Wind Speed Distribution Map for Coastal Areas of Southern Power Grid, the design wind speed for Qionghai Yangjiang is 37m/s, which corresponds to a basic wind pressure of 0.86kN/㎡. Considering the region’s susceptibility to typhoons, it is recommended that this project be designed to withstand typhoons of level 14 and a basic wind pressure of 1.10kN/㎡.

The tender scope includes the procurement of one set of a 25MW/50MWh energy storage system. The delivery period is 45 days from the date of the formal written production schedule notice from the tenderer after the contract is signed and effective. The delivery location is the project site in Yangjiang, Qionghai.
