Of the total quantum of 510 mw, 300 mw is solar power and 210 mw is hybrid power, an official statement said.
“Reliance Infrastructure-led BSES discoms have become the first discom in Delhi and among only a handful in the country to procure hybrid power. Hybrid power is a bundled mix of solar and wind power, wherein one component is atleast 33% of the contracted capacity,” the statement said.
In hybrid power, both the sources of power are co-located at the same location and the pooled power is injected into the electricity system at the same point. The advantage of hybrid power is optimum cost utilisation of the power evacuation network as solar power is primarily a day phenomenon and wind, round-the-clock, it said.
Inked for a period of 25 years, the solar and hybrid power is expected to be available to BSES discoms in 18 months.
“We have been procuring renewable energy from all available renewable sources at economical rates, ensuring minimal burden on the consumers. These agreements are yet another proof of our efforts in this direction. It will provide further impetus to our efforts to provide green and clean power to Delhi consumers,” a BSES spokesperson said.
The statement said the contracts are priced substantially lower than the average cost of power purchase agreements, which are around Rs 5.5 per unit and this agreement will help BSES discoms to fulfil their renewable purchase obligations.
It is pertinent to note that Delhi experiences peak power demand twice in a 24-hour period. While solar power will help the discom meet the day peak, the wind-power sourced from the coastal areas is expected to support the night peak demand. Moreover, the supply of bundled solar and wind power will lessen the variations in scheduling power in comparison to a contract for pure wind power, it said.
The Delhi electricity regulator has written to the Union power ministry seeking deallocation of share of two BSES discoms in the state from
’s Dadri I unit.
The Delhi Electricity Regulatory Commission (DERC) has sought permanent reallocation “on urgent basis entire Delhi’s share of Dadri-I generating station of NTPC to other needy states w.e.f 1st December, 2020 to avoid the burden of fixed cost without any power scheduled to end consumers of Delhi.” BSES discoms plan to surrender power from six NTPC plants and have filed for exiting two such PPAs in DERC.
The DERC letter comes after the power ministry allowed BSES Delhi discoms to exit power purchase agreement with NTPC’s Dadri-I unit, in a first of its kind move that is likely to trigger many such requests. Delhi regulator had also written to the ministry in March this year requesting deallocation of entire 756 mw quantum of Delhi share from Dadri-I. It said the optimisation of power purchase cost of Delhi will benefit power consumers.
