RERC publishes (Renewable Energy Obligation) (Fifth Amendment) Regulations, 2019

Rajasthan Electricity Regulatory Commission (RERC) recently announced (Renewable Energy Obligation) (Fifth Amendment) Regulations, 2019, which shall come into effect from 1st April 2019 provided that the revised RPO for FY 2018-19 shall become applicable from 1.04.2018. The original RPO target was 14.25% for FY 18-19. This has been reduced with retrospective effect.

Amendment in Regulation 4 of the Principal Regulations:

source: RERC

  • If the solar RPO compliance is achieved up to 80%, then the remaining shortfall if any can be met by excess non-solar energy purchase over and above the specified non-solar RPO for that particular year.
  • Similarly, If the non-solar RPO compliance is achieved up to 80%, then the remaining shortfall if any can be met by excess solar energy purchase over and above the specified solar RPO for that particular year.

(3) The RE Obligation for a distribution licensee including deemed licensee for FY 2018-19 and onwards shall be as under:

In our opinion, the reduction in RPO in FY 18-19 from 14.25% to 13.35% defeats the purpose of having RPO targets and runs afoul on various Aptel judgments.  

 

Gujarat announces RE Forecasting and Scheduling regulations, 2019

Gujarat Electricity Regulatory Commission has recently issued Forecasting, Scheduling, Deviation Settlement, and related matters of solar and wind generation sources regulations, 2019 on 19th January 2019. The notifications are effective from the date of notification, however, the deviation charges specified in the regulations will be effective from 1st August 2019.

The key points of the regulations are as below:

  • Deviation accounting:

Absolute Error in % = Actual Generation – Scheduled Generation /Available Capacity (AvC)

  • Eligibility criteria: The regulations will apply to all wind and solar generators having a combined installed capacity above 1 MW connected to the state grid/substation, including those connected via pooling stations, and selling generated power within or outside the state or consuming power generated for self-consumption.
  • Forecasting and scheduling code: Revision of schedule will be allowed if the revision is more than 2% of the previous schedule. For wind energy-based generations, maximum 16 intra-day and for a solar energy-based generation, a maximum of 9 intra-day revisions will be allowed.
  • Aggregation is not allowed of more than one pooling stations or individual generating station connected to a substation.
  • QCA or the wind and solar generator can submit “Day-ahead” and a “week-ahead” schedule  by 9 am every day for each pooling station or each generating station, wherein the Day-ahead schedule can contain wind or solar energy generation schedule at intervals of 15 mins (time-blocks)for the next day, starting from 00:00 hours of the day, and prepared for all 96 time-blocks and Week-Ahead schedule shall contain the same information for the next seven days.
  • The revisions of schedules for solar generators will be effective form 4th time block and there can be maximum of 9 revisions during the day starting from 5:30 hours to 19:00 hours of that day.
  • The revisions for a wind generating plants will be applicable for the entire 24 hours in a day.
  • The QCA will provide payment security to the extent of 110% against the deviation charges in form of Bank Guarantee. The payment security amount for the first year will be worked out considering average deviations observed during the mock trial dor different set of sites:
  1. Wind generating plant of approximately 50 MW capacity at pooling sub-station.
  2. Solar generating plant of approximately 25 MW capacity at pooling sub-station.

The table for the deviation charges and deviation limits is given below:

Deviation charges for wind operators

Deviation charges for solar generators
