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:

RERC announces draft (first amendment) Net metering regulations 2018 for rooftop & small solar grid interactive system.

Rajasthan Electricity Regulation Commission (RERC) has recently notified the draft (first amendment) of net metering regulations, 2018 for rooftop & small solar grid interactive system in Rajasthan. The pilot net metering regulations came in 2015, after that this is the first amendment proposed by the commission. Since the first regulations, the feed-in tariff for solar PV has reduced drastically even lower than feed-in-tariff determined by the Commission for such projects. However, the Rajasthan commission is of the opinion that the tariff determined through auctions for Mega power projects cannot be made applicable for Rooftop solar PV projects which are of the kilowatt capacities (max.1000 kW) due to the higher capital cost of such rooftop projects.

The current amendment also talks about the excess electricity generated by the rooftop generator in the regulation clause 10(3) as follows:

“ Provided that in the event the electricity injected exceeds the electricity consumed during the billing period, such excess injected electricity above 50 units shall be paid by the Distribution Licensee at its Average Power Purchase Cost of the previous year. Provided further that Commission may review the above rate through an order as and when required. Net energy credits less than 50 units under Net Metering achieved in the particular billing period shall be adjusted in the next billing period till credit of 50 units is achieved.”

The regulation will come into effect after the date of notification in the official gazette.

Rajasthan commission has also released a discussion paper recently suggesting that the DISCOMs should purchase green energy directly instead of buying the electricity component form the RE projects.

KERC announces a revised tariff order for rooftop solar plants for domestic consumers

KERC has recently announced an order for the “revision of tariff in respect of new Solar Rooftop Photovoltaic Units of 1kW to 10kW capacity installed by domestic consumers”. The government of Karnataka has set a target of 2400 MW of grid-connected rooftop generation projects under its solar policy 2014-2021. As of August 2018, Karnataka’s installed capacity for both ground-mounted and rooftop solar capacity is 5179 MW. Out of the total installed capacity, only 145 MW is solar rooftop photovoltaic plants (SRTPV) units have been installed & commissioned. Karnataka Electricity Regulatory Commission (KERC) the Commission had issued a Discussion Paper in the matter of revision of tariff in respect of new Solar Rooftop Photovoltaic Units of 1kW to 10kW capacity installed by domestic consumers, on 09.09.2018, inviting comments/suggestions from the stakeholders.

One of the reasons for the poor response for installation of rooftop solar photovoltaic plants by the domestic consumers may be the low Feed-In Tariff (FIT) fixed by the Commission as compared to the relatively higher capital cost of smaller capacity SRTPV units. Hence, the Commission was of the considered view that there is a need to promote smaller capacity solar rooftop power plants by the domestic consumers in order to achieve the desired capacity addition of SRTPV plants in the State.

Post the comments and suggestions, the commission has made some changes as below:

  • The CUF is retained to be 19% % even for 1 kW to 10 kW capacity SRTPV Plants from the 16% CUF earlier.
  • The capital cost for SRPTV plants of 1 kW to 10 kW is decided to be INR 48,000/kW.
  • The generic tariff for grid-connected new Solar Rooftop Photovoltaic Units of 1kW to 10kW capacity installed by domestic consumers at INR.4.15 only per unit (without capital subsidy) and at INR.3.08 only per unit (with capital subsidy).
  • The above-mentioned changes will be applicable to new plants with commissioning date on or after 19.12.2018.

REC trade result – December 2018

The december trading session saw a good price discovery for both solar & non-solar RECs. The market saw a significant price hike in solar as compared to last month. The demand for both solar & non-solar remained consistent while the supply remained limited. As we approach the year-end, the obligated entities are in the process to comply with their obligations and hence the higher demand in order to not face any penalties for non-compliance. However, the highlight of this month’s trade was that solar crossed the floor price of INR 1,000 and reached at INR 1500 at PXIL and INR 1450 at IEX.

Non-Solar: This session the RECs were traded at the price of INR 1255 at PXIL (25.5% above the floor price) and INR 1320 at IEX (32% above the floor price). A total of 3,82,400 RECs were traded in this session leaving an inventory of 21,52,097 Non-Solar RECs. (However, a significant portion of these do not participate in trading as they would either be owned by Discom’s or are for self-retention).

Solar: Total number of solar RECs traded in this session was 1,77,247 (201% increase from the last months’ trade). The clearing ratio was 100% at PXIL & 100% at IEX respectively (w.r.t floor price). RECs traded at the floor price, i.e. INR 1500 at PXIL (50% above the floor price) and at Rs 1450 at IEX (45% above the floor price).

The overall trade volume (5,59,647 RECs) increased by almost 10.65% from the last months’ trade volume (5,05,738 RECs).

DERC announces draft guidelines for group and virtual net metering

Delhi Electricity Regulatory Commission (DERC) announced the draft guidelines under the draft guidelines under DERC (Net Metering for Renewable Energy) Regulations, 2014 for implementation of Group Net Metering and Virtual Net Metering Framework under Delhi Solar Policy 2016. The comments & suggestions on guidelines are accepted till 1st January 2019.

The key points of the guidelines are as below:

  • Group net metering: Group Net Metering is an arrangement where the surplus energy exported to the grid from a solar plant at the location of the solar plant can be adjusted in any other (one or more) electricity service connection(s) of the consumer within the NCT of Delhi, provided these connections are in the same DISCOM territory.
  • Virtual net metering: Virtual Net Metering is an arrangement to give access to the Solar Net Metering facility for consumers who do not have a suitable roof for installing a solar system (e.g. residential consumers who live in apartments, consumers with shaded rooftops) there will be the facility of Virtual Net Metering.
  • In the initial phase, only the government entities will be applicable for utilizing Group and Virtual net metering.
  • The provisions for providing land space shall be governed as per provisions Delhi Electricity Regulatory Commission (Supply Code and Performance Standards) Regulations, 2017 as amended & Orders issued under these Regulations from time to time.

Framework for group net metering:

  • Distribution Licensees shall facilitate Group Net metering, whereby surplus energy exported to the grid from a solar plant at the location of the solar plant can be adjusted in any other (one or more) electricity service connection(s) of the consumer within the same distribution licensee area.
  • Smart meters shall be installed at Generation point(s) and the cost shall be borne
    by the distribution licensee
  • The Distribution Licensee shall show, separately, the energy units exported, the energy units imported, the net energy units billed and/or the energy units carried forward, if any, to the consumer in their bill for the respective billing period.

Framework for Virtual net metering:

  • Consumer(s) can collectively own a solar system under the arrangement of virtual net metering.
  • The adjustment of energy generated from solar plant shall be credited in the electricity bill of each participating consumer on the basis of the share of beneficial ownership in the solar plant at the time of application for connectivity under Virtual Net Metering framework.
  • Under Virtual Net Metering, there is no restriction on intra DISCOM or inter DISCOM transfer of surplus energy as per Delhi Solar policy, 2016. Therefore, in case of inter DISCOM transfer of power due to the physical location of either of Generation plant or Consumer in different DISCOM area, normative distribution losses on account of the transfer of power shall be borne by the consumer.

CERC announces draft (Deviation Settlement Mechanism and related matters) (Fourth Amendment) Regulations, 2018

The CERC has announced the draft (fourth) amendments of Deviation Settlement Mechanism & related matters regulations. The principal regulations came into effect in January 2014 followed by three amendments in December 2014, August 2015 and May 2016 in that order. The previous amendments were notified to solve issues related to grid operations the Deviation Settlement Mechanism (DSM) impact with respect to frequency due to emerging markets. The latest amendments talk about the limitations of the DSM price vector and recommendation for the same.  According to the report prepared by an expert group consisting of representatives from CEA, POSOCO, CTU, and CERC suggestive measures have been given for bringing power system operation closer to the National Reference Frequency.

As per the report, the present DSM has design limitations and since the rates are designed by CERC the changing of rates takes time under the regulatory process and does not catch up with the change in prices in other market segments. The present DSM rates at 50 Hz (178 paise/unit) are linked to the variable charges of a pit-head thermal station whereas the highest DSM rate (824 paise/unit) is linked to the variable charges of the costliest generator (liquid fired). Ideally, the DSM price should capture the Value of Lost Load (VoLL) so that utilities procure adequately in advance so as to meet their universal service obligations.

Few amendments from the draft document are as below:

  • The definition of Area Clearing Price (ACP) & Day Ahead Market (DAM) is included in order to connect ACP & DAM to the DSM prices by considering the factor geography & transmission congestion.
  • The reference frequency band (49.85 Hz to 50.05 Hz) is proposed for the purpose of DSM price vector from the previous frequency band of (49.70 Hz and above).
  • The maximum ceiling limit applicable for average daily ACP discovered in the DAM segment of power exchange at 50.00 Hz is proposed to be 800 Paisa/kWh from 824 Paisa/kWh
  • The Day-ahead market price of the Power Exchange having a market share of 80% or more in energy terms on a daily basis is proposed to be taken into consideration for linking to the DSM price vector. If there is no single Power Exchange having a market share of 80% or more, the weighted average day-ahead price is proposed to be used for linking to the DSM price.
  • It is proposed to link the cap rates for generators using coal/lignite/ APM gas to the energy charges as billed for the previous month is proposed.
  • Reduction in the number of time blocks (from 12 to 6-time blocks) for a change of sign in case of sustained deviation in one direction is proposed.
  • Levy of an additional surcharge of 20% on the daily base DSM payable/receivable in case of violation of the stipulation regarding the change in sign.
  • It is proposed that the total deviation from schedule during a day should not be in excess of 3% of the total schedule for the drawee entities and 1% for the generators and in case of violation 20% of the daily base DSM payable/receivable be levied.
