In the notices, Delhi Electricity Regulatory Commission (DERC) directed BSES Rajdhani Power Ltd and BSES Yamuna Power Ltd to present their case before it tomorrow at a special hearing.
"We have served notices on the BSES discoms to explain their position on the issue in the wake of the government recommendation," DERC chairman P D Sudhakar told PTI.
On Monday, Delhi government had recommended to the DERC to revoke the licenses of BSES discoms if they resort to long outages in areas of their operation citing fund crunch to arrange power.
Warning of a cut in power supplies in the city, state-owned NTPC said BSES discoms have a history of payment defaults and their electricity supply would be curtailed if they fail to pay their dues by Monday.
BSES discoms, which supply power in nearly 70 per cent areas in the city, had informed government that they did not have money to buy power and the city may reel under long outages if funds are not provided to them.
In a notice to BRPL, NTPC had said the company has not been able to renew letter of credit for payment security mechanism as per provision in the power purchase agreement.
The BRPL appealed to NTPC to allow reinstatement of letter of credit (LC) in 30 days.
"NTPC not at any risk of default for BSES Rajdhani payments. NTPC has rejected plea and sought LCs within 7 days," BRPL said.
The company also sought "cooperation" from Delhi government and NTPC to "resolve matter in interest of 19 lakh consumers".
