Solar energy projects in China are reaching new levels
SUSTAINABLE DEVELOPMENT/ENERGIA LIMPIA XXI. Sungrow, the global leading inverter solution supplier for renewables, along with Huanghe Hydropower Development Co., Ltd., announced that it is supplying PV inverter solutions and energy storage systems to a 202.86MW/202.86MWh PV-plus-storage project in Northwest China’s Qinghai Province, which is considered the largest solar plant in the world with 2.2 GW.
Technologically advanced “PV+ESS” solution
This project is located in a vast desert that is becoming a hub of mounting solar plants and one of China’s electricity transmission basesapplying UHV (Utra High Voltage) technology to tranfer the electricity from west to east across the nation in a bid to maximize the consumption of clean energy. A report carried by Energía Limpia XXI states that Huanghe Hydropower, the leading renewable energy entity, is playing a pivotal role in the multi-energy complementary field of water, wind, solar and storage and sets stringent requirements in terms of the innovation of the PV-plus-storage technology. As a response, Sungrow provides the tailor-made PV-plus-storage solution, comprising of the integrated energy storage system and the world’s most powerful 1500V string inverter SG250HX (namely SG225HX in China), which enable a competitive cost, easy O&M and a shorter construction duration.
Embedded with the sub-array energy management function, the solution can control the smooth output of the solar and storage,improving the prediction accuracy of solar generation and increasing clean energy consumption. The customized AC-coupled low-voltage design can guarantee cost-savings for the customer. Furthermore, the flexibly built microgrid system with Sungrow PV and energy storage system is able to supply electricity in the early construction period and slash the construction time.
Creating the future of “1+1 > 2”
“The LCOE will continue to decrease if growing innovative PV technologies are applied. The energy storage applications are getting to be more cost-saving when more integrated energy storage systems are created. Looking forward to the post grid-parity era, PV will be deeply integrated with energy storage technology and highly support the stability of the grid,” said Jack Gu, Senior Vice President of Sungrow, when asked about the trend of the PV-plus-storage segment.
“The integration of PV and energy storage is not a simple and mechanical combination of PV and ESS system, but the deep analysis and integration of the whole system, so as to achieve a leap forward of ‘1+1 > 2’ in terms of efficiency and performance,” he added.
As one of the pioneers in the industry to implement PV-plus-storage technology, Sungrow has participated in over 900 energy storage projects as of December 2019, of which PV-plus-storage projects spread across the United States, China, Japan, the UK, Maldives, Australia, Africa and other major regions. Indeed, all projects are running stably with zero safety accidents.
China is moving ahead to become carbon neutral in 2060
In remarks at the United Nations General Assambly in September 2020, President Xi Jinping “The Paris Agreement on climate change charts the course for the world to transition to green and low-carbon development. It outlines the minimum steps to be taken to protect the Earth, our shared homeland, and all countries must take decisive steps to honor this Agreement. China will scale up its Intended Nationally Determined Contributions by adopting more vigorous policies and measures. We aim to have CO2 emissions peak before 2030 and achieve carbon neutrality before 2060. We call on all countries to pursue innovative, coordinated, green and open development for all, seize the historic opportunities presented by the new round of scientific and technological revolution and industrial transformation, achieve a green recovery of the world economy in the post-COVID era and thus create a powerful force driving sustainable development”.
