On November 13th, the world's first gigawatt level offshore photovoltaic project - the first batch of photovoltaic power generation units of the 1 million kilowatt offshore photovoltaic project invested by National Energy Group Guohua Investment in Shandong Kenli - was successfully connected to the grid, becoming the world's first and largest offshore photovoltaic project to be successfully connected to the grid. It has played a leading and exemplary role in the large-scale development of China's and even the world's offshore photovoltaic industry.



The project is a three-dimensional, layered, and truly offshore photovoltaic project currently located in an open sea area around the world. It is situated 8 kilometers offshore from Dongying City, Shandong Province, and was approved by the State Council in July of this year. The project covers an area of approximately 1223 hectares and has a total installed capacity of 1 gigawatt. The project is the first in the world to use large-scale offshore steel truss platform fixed pile foundation construction technology to install 2934 photovoltaic platforms, with a single platform length of 60 meters and a width of 35 meters. It is the first offshore photovoltaic project in the domestic photovoltaic field to apply 66 kV submarine cable+land cable high-capacity and long-distance transmission lines. The offshore photovoltaic project is constructed using block power generation and centralized grid connection scheme.


After the project is completed and put into operation, it is expected to generate 1.78 billion kilowatt hours of electricity annually, save about 503800 tons of standard coal annually, and reduce carbon dioxide emissions by about 1.3447 million tons annually. At the same time, the project also adopts the "integrated fishing and photovoltaics" development method, which will realize the three-dimensional comprehensive development and utilization of fishery aquaculture and photovoltaic power generation. It is expected that the annual income of fishery aquaculture will exceed 27 million yuan, further enhancing the comprehensive utilization value of the sea area.



In recent years, Guohua Investment Company of the National Energy Group has actively responded to Shandong Province's strategy of building a strong marine province in the new era, and has made every effort to enter the offshore photovoltaic industry, obtaining the 1.7 million kilowatt offshore photovoltaic new energy index. Currently, the first batch of 1 million kilowatt offshore photovoltaic projects have achieved grid connected power generation, laying a good foundation for accelerating the layout of new quality productivity and expanding new industries.
