Jilin Power Grid's renewable energy utilization rate reached 97.7% in 2019

On January 6, the reporter learned from State Grid Jilin Electric Power Co., Ltd. that the utilization rate of new energy in Jilin power grid reached 97.7% in 2019, an increase of 3.8 percentage points year-on-year, and the level of new energy consumption has reached a new level.

In 2019, Jilin Power Grid added 529,000 kilowatts of new energy installed capacity (438,000 kilowatts of wind power and 91,000 kilowatts of photovoltaic power), and the cumulative installed capacity of new energy reached 8.315 million kilowatts; the power generation of new energy units was 15.44 billion kWh, an increase of 19.6% year-on-year; the proportion of new energy power generation reached 16.7%, an increase of 1.9 percentage points year-on-year. The annual utilization hours of wind power and photovoltaic power generation units were 2,216 hours and 1,468 hours, respectively, an increase of 159 hours and 185 hours year-on-year; the utilization hours of wind turbines reached a new high.

In order to further tap the potential of power consumption in the province, State Grid Jilin Power optimized the grid structure, released the short-term overload capacity of the main transformer, added regional stabilization devices, and completed the high-voltage ride-through transformation of the wind farm; carried out the Jilin power grid's new energy consumption measurement and calculation, made good predictions on new energy power generation and source-grid-load interaction, optimized the operation mode of conventional power sources; carried out power market auxiliary services to stimulate the enthusiasm of thermal power units to participate in peak load regulation. In 2019, Jilin Power Grid increased wind power generation by 1.395 billion kWh through paid peak load regulation through power market auxiliary services, an increase of 20.6% year-on-year.

In order to promote cross-provincial and cross-regional transmission, State Grid Jilin Electric Power actively carried out cross-regional medium- and long-term transactions of new energy electricity, giving full play to the transmission capacity of Lugu DC and Gaoling DC channels, and the scale of transmission has grown steadily. In 2019, the wind power transmission transaction volume of Jilin Power Grid reached 3.551 billion kWh, accounting for 31.3% of wind power generation. At the same time, the company has done a good job in cross-regional spot trading of surplus wind power, organized renewable energy companies to actively participate in short-term spot trading, and increased mutual assistance support. The total cross-regional spot trading volume was 104 million kWh and the out-of-province peak load support volume was 214 million kWh throughout the year.

State Grid Jilin Power will continue to strengthen its sense of responsibility, enhance departmental coordination, and take multiple measures to serve the development of new energy to ensure the completion of the 2020 new energy consumption target.
