Legal analysis: Spontaneous self-use surplus electricity is connected to the grid, which means that the power generated by the distributed photovoltaic power generation system is mainly used by the power users themselves, and the excess power is connected to the power grid. It is a business model of distributed photovoltaic power generation. In this operating mode, the photovoltaic grid-connected point is located on the load side of the user's electricity meter. It is necessary to add a photovoltaic meter for reverse transmission of electricity or to set the grid electricity meter to two-way measurement. The user directly uses the photovoltaic electricity to save electricity bills. Directly enjoy the electricity sales price of the power grid, and the delivered electricity is measured separately and settled at the specified on-grid electricity price.
Legal basis: "Notice of the National Development and Reform Commission on Improving the Benchmark Electricity Price Policy for Onshore Wind Power and Photovoltaic Power Generation" Article 2 Distributed photovoltaic power generation projects constructed using building roofs and ancillary sites must be registered in the project You can choose one of the modes of "spontaneous self-use, surplus electricity to the Internet" or "full amount of electricity to the Internet"; projects that have been implemented according to the "spontaneous self-use, surplus electricity to the Internet" mode, when the electricity load is significantly reduced (including disappearing) or the supply If the electricity consumption relationship cannot be fulfilled, it is allowed to change to the "full Internet access" mode. The power generation of the "full grid" project is purchased by the power grid company according to the benchmark electricity price of the local photovoltaic power station. To choose the "full grid-connected" mode, the project unit must apply for change filing with the local energy authority, and is not allowed to change back to the "self-consumption, surplus power grid-connected" mode.
