Green power surges, energy storage first. Following the successful commissioning of the first phase of the energy storage plant, Lishui will soon usher in another "super power regulator"---Datang Nanjing Thermal Power Co., Ltd. 50 MW/100 MWh Phase II Centralized Shared Energy Storage Power Plant.Has entered the grid sprint stage, is expected to the end of this month officially "on-line".
Into the project construction site, 10 groups of energy storage units neatly arranged, a large crane slowly moving, workers shuttling between the white prefabricated cabin, cable laying, system commissioning ...... a hot construction scene. This covers an area of 6.7 acres of "super power warehouse" is ready to go, all aspects of the orderly progress.
"There are 45 professional and technical personnel working together on the site, and we all work together to ensure that the project will be completed on time and under the premise of ensuring safety and quality for the commissioning." Xu Dong, secretary of the company's party committee and chairman of the board of directors, said that it is now a critical period for the system's power-carrying debugging, and every parameter has to be accurate to the millisecond level.
The second phase of the project adopts lithium iron phosphate batteries, and through optimizing the operation mode of energy storage, it can effectively guarantee the efficient consumption of new energy and alleviate the pressure of grid peaking.Each energy storage unit contains 2 battery prefabricated compartments and 1 PCS boosting compartment, just like a well-built "giant charging treasure" square. The cable bridges between the modules are neatly laid, the fire blocking is carefully in place, and all kinds of pipelines are clearly labeled.
Upon commissioning of the project, theIt is expected to increase clean energy consumption by about 32 million kWh per year, which is equivalent to reducing the consumption of standard coal by about 16,000 tons and reducing carbon dioxide emissions by about 50,000 tons.
Standing in the second phase of the project site, the first phase has been put into operation of the energy storage power station quietly standing on the side, the two "twin power station" echo each other, will form a strong energy storage matrix.
Compared with the Phase I project, the Phase II project has achieved system optimization in many aspects: through design optimization, the equipment procurement and engineering cost is reduced by about 30 million yuan; technically, the use of higher energy density electric core has improved the overall performance of the system while optimizing the construction land from 11.92 acres to 6.79 acres, thus realizing intensive and efficient land use.
"The synergistic operation of the two phases of the project will effectively alleviate the pressure on the local power grid during peak times, and dissipate surplus power during low valleys." Xu Dong introduced, with the grid into the final countdown, this cohesion of scientific and technological innovation and green development of the "super charging treasure".It will significantly improve the regulation capacity and operation stability of Lishui and even Nanjing power grid, guarantee the reliable power consumption of enterprises and residents, and add green kinetic energy and stable support for Nanjing power grid.
