The state-run Power Grid Corporation (PGCL), which acts as western regional load dispatch centre, in a warning letter has asked MSEB Holding Company not to overdraw power from the grid below 49 Hz it order to avoid grid collapse.

Maharashtra has been overdrawing 500 mw from the western grid mainly to overcome its burgeoning power demand in the state. The power deficit of the entire western region is around 6,000 mw. Despite carrying out a daily load shedding of 4,500 mw the Maharashtra State Electricity Distribution Company (MahaVitaran) is forced to overdraw power from the grid which is a serious threat to the grid security.

PGCL in its communication. PowerGrid Corporation sources told FE The matter is quite serious as Maharashtra is the only state which is overdrawing over 500 mw from the grid below 49 Hz. There is danger that the grid may collapse disrupting power in other parts of the western grid. We have asked Maharashtra to follow grid discipline and avoid overdrawal. We are aware that the sudden tripping of 500 mw its Chandrapur thermal unit and two other units from the central sector have added power deficit. Chandrapur VI has come on line. Maharashtra should follow load management schedule.

Sources from the Maharashtra State Power Generation Company and MahaVitaran admitted that the non availability of over 1,500 mw both from Chandrapur and from central sector had increased power shortage. The state has been taking utmost care to maintain grid discipline and the overdrawal would be done when other constituents are underdrawing the power from the grid

Meanwhile, about 6,500 mw of power would be added by private companies in Maharashtra by March 2010.
