The Delhi Electricity Regulatory Commission (DERC) has approved two power sale agreements (PSAs) between BSES Rajdhani Power Limited (BRPL) and PTC India Ltd for the procurement of 100 MW of wind power. This will help BRPL meet its non-solar renewable purchase obligation (RPO).

BRPL had petitioned the Delhi commission seeking adoption of tariff for purchase of 100 MW of wind power from PTC India Limited and for the approval of the PSAs dated July 21, 2017, entered by BRPL and PTC India Limited.

The tariff of the PSA will be ₹3.53 (~$0.050)/kWh; ₹3.46 (~$0.049)/kWh (tariff quoted by developer), along with PTC India Limited’s trading margin of ₹0.07 (~$0.00099)/kWh.

Back in June 2016, the MNRE had approved a program to set up 1,000 MW of interstate transmission system (ISTS)-connected wind projects. Then in October 2016, the Solar Energy Corporation of India, (SECI) on behalf of PTC India Limited, tendered 100 MW of ISTS-connected wind power projects.

Green Infra Wind Energy Ltd. and Inox Wind Infrastructure Services Ltd. both won the bid to develop 50 MW of wind projects each by quoting tariff of ₹3.46 (~$0.049)/kWh. PTC India Limited had entered power purchase agreements with the winning bidders.

While examining the petition and submissions made, the commission observed that PTC India Limited has made two agreements in respect of each transaction, one power purchase agreement with the generator and then back to back PSA with BRPL for the supply of power.

The Delhi commission also observed that the tariff has been determined through a competitive bidding process as per the guidelines issued by the Ministry of New and Renewable Energy (MNRE). The DERC found the PSAs dated July 21, 2018, entered by PTC India Limited and BRPL to be in order and therefore approved them.

In July 2018, BSES Yamuna Power Limited (BYPL) had entered PPA to procure 100 MW of wind to meet its non-solar RPO.
