  On December 16, China General Nuclear Power Group (hereinafter referred to as CGN) Shandong Laizhou Tushan 600MW "Salt-Photovoltaic Complementary" project was fully connected to the grid for power generation.   This project is the largest supporting energy storage project in Shandong Province. Through the new composite industrial model of "Salt-Photovoltaic Complementary", it has successfully created a benchmark demonstration project of "one site for multiple uses", which has important demonstration significance for the exploration of new green energy solutions of "photovoltaic + energy storage" in my country.   The project is located in Tushan Town, Laizhou City, Yantai City, Shandong Province. It is the largest photovoltaic project in Shandong Province in 2022 in market-oriented bidding. It is also CGN's first "Salt-Photovoltaic Complementary" power generation project. Construction started in June 2024, with an installed capacity of 600 MW and a new 220 kV booster station. The project is equipped with independent energy storage at a ratio of 40.7%, that is, 244.2 MW/488.4 MWh, and has all the functions of independent energy storage system. The subsequent energy storage system can not only be used to regulate the power supply of photovoltaic power generation, but also participate in market-oriented transactions to improve the economy and flexibility of the power system. It is a concrete practice of the new green energy solution of "photovoltaic + energy storage".   Jiang Tonghai, general manager of CGN New Energy Shandong Branch, said that the project laid photovoltaic panels in the salt pond area, involving an area of ​​about 9,765.2 mu of salt fields. On the premise of ensuring the output and quality of sun-dried salt, the comprehensive utilization of light resources has realized the "water photovoltaic power generation, water surface evaporation brine, underwater aquaculture" "salt-light complementary" new composite industrial model, successfully created a benchmark demonstration of "one land for multiple uses", and maximized the utilization of land resources.   The solar panels of this project adopt double-sided double-glass technology. The brine reflects light to the back of the module under the irradiation of sunlight, which can increase the power generation efficiency of the project by more than 2% to 3%. Photovoltaic modules have a thermal effect, which can significantly increase the temperature of the salt pond, which is very beneficial for brine concentration, and realizes the complementary and win-win situation of salt production and photovoltaic power generation. The thermal effect of photovoltaic modules creates a natural growth environment for brine worms in the brine pools within the salt fields, providing high-quality biological bait for aquaculture.

It is reported that on December 4, the first 100 kW/124 kWh solid-state battery energy storage power station in North China Oilfield was successfully connected to the grid and put into operation at Wangsan Station of Oil Production Plant No. 3. This is the first independent solid-state battery energy storage power station of PetroChina, marking another solid step for North China Oilfield in the field of clean energy. The New Energy Research Institute of Oil and Gas Technology Research Institute conducted in-depth research and demonstration in the early stage of the project. After several rounds of evaluation and discussion, it finally selected polymer electrolyte solid-state battery energy storage technology to form independently designed supporting products. According to the planning of the new power system of North China Oilfield, Oil Production Plant No. 3 carefully organized the on-site implementation of the project. The energy density of this product can reach 280 watt-hours/kilogram. The energy storage battery cell will not explode or burn after puncture and shooting tests, and can operate normally in extreme environments of minus 40 degrees Celsius. From the overall design point of view, the power station adopts the outdoor layout of prefabricated cabins, consisting of 1 battery cabin and 1 booster integrated cabin. The design cycle is more than 6,000 times and the service life can reach more than 10 years.   At present, Wangsan Station has a total of 11 sets of energy-consuming equipment, 5 oil wells and 2 water wells under its jurisdiction, with an annual power consumption of about 960,000 kWh. The photovoltaic installed capacity in the station is 479.6 kW, and the annual power generation is about 570,000 kWh. After the solid-state battery energy storage power station is put into operation, it adopts two operating modes: green power charging and discharging and oilfield power grid peak-valley arbitrage. The energy conversion efficiency of the energy storage battery exceeds 90%, and it is expected to supply more than 6,000 kWh of electricity to the oil wells in the station in a single month. After the project is running normally, the Oil and Gas Technology Research Institute will track, evaluate and analyze key indicators such as the peak-shaving capacity, power quality conversion efficiency, source-grid-load-storage coordinated scheduling and project economic benefits of the energy storage power station, provide support for the construction of the clean energy highland of the North China Oilfield, and have far-reaching significance for the construction of a new power system and a new energy storage system. In the next step, North China Oilfield will continue to build a series of professional technologies for all new energy industries integrating wind power, photovoltaics, energy storage, etc., and use different industries to penetrate into the power generation side, power grid side, and user side, truly forming a new green energy su...

  Recently, South Australia's rooftop solar PV broke 100% of grid demand contribution, reaching a peak of 107.5%.   According to OpenNEM data, at about 13:45 on November 17, South Australia's rooftop solar PV generation reached 1,720 MW, meeting 107.5% of the state's demand. This is the latest milestone achieved by the state, which exceeded 100% of photovoltaic power generation for the first time last month.   On the other hand, large-scale ground-mounted solar PV only met 0.7% of demand, providing 11.5MW of electricity.   This is the latest milestone achieved by South Australia in its energy transition, demonstrating the successful promotion and application of renewable energy technologies. According to PV Tech, the state achieved more than 100% renewable energy supply during the winter of 2024 (August 26 to September 1).   During this period, rooftop solar PV generation accounted for 21.1% of 102.2%, generating about 56GWh a week, with an average price of AUD 52.02/MWh (US$33). On the other hand, large-scale ground-mounted solar power accounted for 3.9% of the overall energy mix, about 10.4GWh, with an average price of AUD 30.96/MWh. South Australia plans to achieve 100% renewable energy generation by 2027 South Australia's strength in the renewable energy sector has enabled it to target 100% wind and solar photovoltaic by 2027, and in July 2024 became the first state in Australia to sign a renewable energy transition agreement with the federal government. The agreement will provide developers with guarantees by the state government to support the development of at least 1GW of solar and wind power generation projects. The federal government's support will also provide the grid with 400MW of new energy storage projects to provide additional stability and flexibility as the grid transitions to variable renewable energy. In signing the agreement, South Australia must commit to implementing its "Hydrogen Jobs Plan", establishing its own specific grid reliability mechanism and benchmark to replace the national framework, and working with the federal government to implement policies, practices and processes to improve community participation. Western Australia becomes the second state to sign such an agreement since South Australia signed it, with plans to develop at least 6.5TWh of wind and solar projects, as well as 1.1GW of new energy storage to help keep the grid stable.
