|Renewable Energy Projects >> Medium Scale Distributed Generation (MSDG) Project|
In 2010, the Central Electricity Board (CEB), in collaboration with the Ministry of Energy and Public Utilities, opened up the access to the national electricity grid through the launching of the Small Scale Distributed Generation (SSDG) project.
The SSDG project, however, only caters for low voltage connected renewable energy systems, with capacities of less than 50 kW. This 50 kW technical limit was set following a consultancy exercise funded by the UNDP. For renewable energy projects with capacities of greater than 50 kW, they have to be connected to the medium voltage network (22kV) and, accordingly, they do not fall within the ambit of the SSDG Grid Code.
In this respect, two new Grid Codes have been established by the CEB to allow the integration of Medium Scale Distributed Generation (MSDG) projects, which comprise larger capacity photovoltaic, wind turbine, mini-hydro, and biomass electricity generation systems.
The two new Grid Codes are as follows:
The maximum permissible installed capacity per customer for MSDG projects has been set to 2 MW. As regards the total capacity of MSDGs that can be installed on a given 22 kV distribution feeder, they are detailed in the respective Grid Codes.
