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 commission in this amendment will fix the minimum percentage of the total consumption of electricity in the area of the distribution licensee for the purchase of energy from renewable energy sources taking into account availability of such resources & impact on retail tariffs. Further, the Ministry of New and Renewable Energy Sources (MNRE) is aiming to achieve 175 GW renewable energy until 2022 and hence has suggested the long-term trajectory of RPOs for non-solar as well as solar for the states & UTs.

Under the obligations notified by Ministry of Power (MoP) which are on the total consumption of the electricity by an obligated entity excluding consumption met by hydro sources of power & flexibility of 15% is also allowed to the obligated entities in the meeting of RPO from either of their solar or non-solar power.

Earlier, the Commission had fixed the RPO targets for FY 2017-18 and FY 2018-19 in line with MoP, where there was a steep increase as compared to the RPO trajectory specified for earlier years. It was observed from the data submitted by the  Rajasthan Discoms regarding RPO target vis-a-vis achievement from FY 2013- 14 to FY 2017-18 (provisional) that actual achievement was less than the targets, in particular for FY 2017-18, the gap was huge. Considering that in addition to making up for the past shortfall in meeting RPO directed in the order dated 14.11.2017. It is observed from the past experience that when the RPO was increased steeply a huge gap was observed in the achievement of RPO targets by the state discoms even for FY 2017-18.

Hence, in the current amendment, the commission has decided that the RPO trajectory may be so designed & notified in such a manner that it becomes practical for the discoms to achieve their targets. Considering a CUF for solar-21%, wind-20% & Biomass-80% with a target addition of 700-750 MW of solar & 250-300 MW of non-solar.

RUVNL on behalf of the discoms have requested that a total RPO of 21% may be achieved by the year 2023-24 instead of 2021-22 and the trajectory may be modified from the year 2018-19 onwards as stated above.

Amendment in Regulation 4 of the Principal Regulations:source: RERC

Provided that on the achievement of Solar RPO Compliance to the extent of 80% and above remaining shortfall if any, can be met by excess Non-solar energy purchased beyond specified Non-solar RPO for that particular year.

Provided further that on the achievement of Non-Solar RPO Compliance to the extent of 80% and above, remaining shortfall if any, can be met by excess solar energy purchased beyond specified Solar RPO for that particular year.”source: RERC

The sub-regulation (3) shall be substituted with the following: “(3) The RE Obligation for a distribution licensee including deemed licensee for FY 2018-19 and onwards shall be as under:source: RERC

Provided that the energy generated from Biomass, Biogas, Biomass Gasifier and Municipal Solid Waste (MSW)/Waste-to-Energy (WtE) based sources shall be covered under the Biomass category: Provided further that in case of insufficient availability of energy from Biomass-based sources during a year, the shortfall can be made good by Wind Energy and to this extent, RPO for wind would be increased.

Provided also that on the achievement of Solar RPO Compliance to the extent of 80% and above remaining shortfall if any can be met by excess Non-solar energy purchased beyond specified Non-solar RPO for that particular year.

Provided also that on the achievement of Non-Solar RPO Compliance to the extent of 80% and above, remaining shortfall if any can be met by excess solar energy purchased beyond specified Solar RPO for that particular year.”

 

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
