Key points and trends in supervision of investment performance of typical power grid projects

Second, more attention is paid to the efficiency and benefits of project operation. In 2017, the supervision content clearly adopted the actual operation results to replace the original operation analysis. The key indicators after the project is put into operation are compared with the expectations to determine whether the expectations are met. It is not just a project cost analysis like the supervision requirements in 2013 and 2014, but an analysis of the revenue such as the transmission volume after the project is put into operation. In addition, with the advancement of supervision work, the supervision content is more detailed, and the requirements for supporting materials such as attachments provided are further refined.

Third, we will continue to track the investment benefits of key projects. In 2017, we added a list of "look back" projects to the supervision. We selected typical power grid projects that have been inspected in previous years and continued to track the changes in benefits. Through "look back", we can continue to track the operation of typical power grid projects in the next few years and further determine the investment benefits.

Suggestions on Improving the Investment Results of Power Grid Projects

First, we will strengthen the overall coordination of power grids and improve the utilization efficiency of power grid projects. Based on the grid structure of the project, we will coordinate dispatching agencies to optimize the operation mode, do a good job in safety verification, and improve the utilization rate of power grid projects. We will innovate transaction methods, fully tap the time and space value of the power grid, promote the reduction of terminal electricity costs, and improve the utilization efficiency of transmission channels.

The second is to optimize the investment structure of the power grid and change the growth mode of the power grid. The power grid is an important foundation for supporting the development of the national economy. In the past, the demand for electricity has grown rapidly for a long period of time, and the investment in the power grid has paid more attention to the construction of new power transmission and transformation projects. At present, the power grid has entered a stage of high-quality development, shifting from meeting basic electricity demand to high reliability and high-quality services. The growth of investment in new power transmission and transformation projects has slowed down, and investment in power grid technical transformation has gradually increased. New businesses and new formats such as electric energy storage and energy Internet are constantly innovating. It is urgent to optimize the investment structure of the power grid from the perspective of improving operational efficiency and improve the operational efficiency of existing power grids.

Third, deepen the construction of the electricity spot market and improve the level of orderly electricity consumption. Establish an electricity market with medium- and long-term transactions as the main and spot transactions as the supplement, improve the market-oriented electricity balance mechanism and price formation mechanism, guide electricity production and consumption with flexible market price signals, maximize the release of electricity optimization space, and improve the efficiency of power grid operation.
