The DTL said although it has invested a lot to strengthen the major transmission network in the city, the failure of BYPL to upgrade the distribution system often leads to local faults resulting in long outages.
Various areas, where BYPL supply power, have been facing power cuts for upto six to seven hours primarily due to breakdown of the distribution network when the demand goes up. Often the distribution network fails to hold the increasing load and it breaks down.
BYPL CEO Ramesh Narayanan, however, refuted the charges saying DTL's transmission infrastructure in East and Central Delhi was very weak because of which power supply has been affected.
"The central and east Delhi areas are very vulnerable and DTL will have to improve its network in these areas," he said reacting to DTL's charges.
Unhappy with performance of power distribution companies, Chief Minister Sheila Dikshit last week had directed them to improve their infrastructure and submit weekly report to the government about their operations.
DTL public relations officer Rishiraj said transmission capacity in Central Delhi is more than double of the distribution capacity.
Similarly, he said East Delhi, the transmission capacity in East Delhi is 1,730 MVA as against distribution capacity of 1,477 MVA.
Rishiraj said Delhi Transco had planned to establish two 220 KV Substations in East Delhi, one at Gazipur and the second one at Preet Vihar but for which BYPL was supposed to provide the land.
"For both of substations land is in the procession of BYPL and it has not yet been handed it over to DTL inspite of regular persuasion. The decision to hand over the land was taken by the Chief Secretary in February last year," Rishiraj said.
He said DTL is setting up a 400 KV substation at Harsh Vihar which is nearing completion. "But BYPL has not laid 66KV lines to get power supply from it. In absence of 66 KV lines BYPL would be unable to supply the power received from 400 KV substation."
