According to the State Electricity Supervision Bureau, the majority of PV projects connected to Hubei Grid are single large-scale PV power plants, two of which are 150 MW in capacity. A further eight provincial-level unified power plants have more than 100 MW capacity, with the total installed capacity reaching 910 MW, around 60% of total PV installation.
It is projected that there will be 1.2 GWh of solar PV electricity to be connected to the Hubei grid over the course of 2016. During the 13th 5-year Plan period, the total capacity of PV power generation will reach 3.8 GW, and new energy installation will account for 15% of the total installation connected to the grid.
According to the bureaus report, support from the State Grid Hubei Electric Power Company in terms of grid services and scheduling and operation served to boost the growth of PV installations.
The utility company gave priorities to scheduling and consuming this new energy, achieving 100% PV power consumption. In operation, the utility followed the principle of prioritizing PV scheduling and grid-access in arranging grid operation mode, and drafted the PV power generation schedule according to its maximum adjustable output, playing the role of the large grid to fully secure that 100% consumption of PV power.
In addition, prior to the grid connection of these PV projects, the utility opened a green channel for those PV power plants that have difficulties in accessing lines and issues in commissioning on time, providing its own grid lines for free to help these PV power plants connect to the grid as planned.
As stated, Hubei Province has not fully realized the PV construction scale target set by the National Energy Administration (NEA); the aforementioned 800 MW PV installation largely accounts for the remaining 2014 and 2015 targets.
