Himachal Pradesh Electricity Regulatory Com-mission Determines APPC for 2016-17

The Himachal Pradesh Electricity Regulatory Com-mission (HPERC) recently came up with its order on the Average Pooled Power Purchase Cost (APPC) for the financial year 2016-17.The definition of APPC followed by HPERC is in line with the CERC defini-tion and can be read as:

“Pooled Cost of Purchase means The weighted average pooled price at which the distribution licensee has purchased the electricity including  cost of self-generation, if any, in the previous year from all the energy suppliers long-term and short-term, but excluding those based on renewable en-ergy sources, as the case may be.”

The APPC for the financial year 16-17 has been deter-mined as Rs. 4.16 per Unit, by the commission which shall continue for further period with such variation or modification as may be ordered by the Commission for the next financial year.

The APPC for FY 16-17 is 8.23% higher as compared to the APPC of FY 15-16.The graph given below depicts the APPC’s determined by HPERC over last four years and how the APPC rates have in-creased over the past three years :

Draft KERC (Procurement of Energy from Renewable Sources) Fourth Amendment, Regulations 2016

KERC has notified Fourth Amendment to KERC (Procurement of Energy from Renewable Resources) Regulations on October 26th, 2016. The draft of the proposed amendment is available in The highlights of the amendment are:

  1. RPO obligation is on captive plant, grid connected plants and open access consumers only .Hence non grid connected captive plants are free from RPO obligation in Karnataka state.
  2. Every distributions licensee, captive consumer and open access consumers may purchase REC or consume electricity generated from its own Renewable Energy Power Plant whether grid connected or otherwise, to meet its RPO either entirely or partly.
  3. The obligation of distribution licensees to purchase electricity from solar energy may be fulfilled by purchase of solar REC’s only.
  4. The capacity of Renewable Energy Power Plant owned by the obligated entity shall not be less than 250Kw.

KERC has invited written comments/views/suggestions on the proposed amendment latest by November 26th 2016 from interested parties.

UERC Order on Non Compliance of RPO

UERC Maintains its tough stand for non compliance of RPO. In a recent order the Uttarakhand Electricity Regulatory Commission has directed UPCL to procure non-solar RECs equivalent to 7.50% of unmet non-solar RPO up to FY 2015-16 latest by 31st July’16. UPCL had submitted the following unmet RPO data to the commission:

The Commission has directed UPCL to meet the overall RPO FOR 2016-17 which is 8% for non solar and 1.5% for solar, either through purchase of energy from RE sources or through purchase of RECs equivalent by March, 2017. The Commission has denied UPCL to continue carrying forward of all the unmet non-solar RPO since, it has failed to tap the available power due to its own dilapidated distribution system for evacuation of power.

Also as mentioned in the order, Non-compliance of RPO will attract action against the officers responsible for compliances of regulations.

Earlier in year 2014, UERC had considered UPCL’s non-compliance as willful contravention of the direction of the Commission and had imposed penalty of Rs.20, 000/- on the Managing Director of UPCL. Thus this seems to be a strict order but in a positive direction which will help in streamlining the REC market overall.

MNRE Scheme for setting up of 1000 MW CTU-connected Wind Power Projects

The Ministry of New and Renewable Energy recently sanctioned the scheme for setting up of 1000MW CTU- connected Wind Power Projects by Wind Project Developers on build, own and operate basis. However, the capacity may go higher than 1000 MW, if there is higher demand from Discoms of non-windy States.

The Government of India has set an ambitious target of target of achieving 175 GW power capacity from renewable energy resources by 2022 and out of this 60 GW to come from wind power.

In order to facilitate transmission of wind power from these windy States to non-windy States provisions have been made in the Tariff Policy to waive the inter-state transmission charges and losses for wind power projects.

Some of the important highlights are:

  • The selection of wind power projects under the Scheme will be through a transparent e-bidding process followed by e-reverse auction for eligible bidders for procurement of wind power at tariff discovered through open competitive bidding process. SECI will develop guidelines for e-bidding process.
  • MNRE will play an important role by issuing Guidelines for transparent bidding process for implementation of the Scheme.
  • SECI will develop a suitable mechanism for monitoring the performance of the projects and will act as the nodal agency for implementation of this Scheme.
  • The objective of the scheme includes:
    • To facilitate supply of wind power to the non-windy states at a price discovered through transparent bidding process;
    • To encourage competitiveness through scaling up of project sizes and introduction of efficient and transparent e-bidding and e-auctioning processes
    • To facilitate fulfillment of Non Solar Renewable Purchase Obligation (RPO) requirement of non-windy states.
