Unexpected technical issues have put spanner in the works of KSEB Limited's plans to provide grid connectivity to roof-top solar plants. The plan was to make 13 roof-top solar plants grid-connected by the end of July. KSEB Limited's renewable energy and planning director K Valsalakumari conceded that only one such plant could be connected to the KSEB grid. Sources said that it had become virtually impossible to provide connectivity in most of the cases.
"When the KSEB switches off power in the grid, it has been found that there is a dangerous flow from the solar plant to the grid. When the grid is switched off, now power should flow through it. In other words, the two mechanisms cannot be synchronized in most of the cases," a source said. Even KSEB sources admit that the grid-connectivity technology needs to be fine-tuned.
