The project adopts a grid-connected mode of "self-generation and self-consumption, with the surplus energy fed back to the grid, with a grid-connected voltage level of 400 kV. The distributed photovoltaic grid-connected power generation substation system follows an overall design scheme of "block power generation, centralized grid-connection." The approach yields remarkable energy saving and environmental benefits. Compared to thermal power generation of equivalent capacity, it can reduce standard coal consumption by 119.39 tons decrease smoke and dust emission by 99.01t, reduce CO? emissions by 362.91tons, and lower SO? emissions by 10.92 tons annually. Correspondingly, it reduces wastewater emissions as well. Not only does this initiative provide green and clean power for the enterprise, but it also alleviates environmental pressure by contributing to sustainable practices.
