Telangana announces final DSM regulations for wind and solar

Recently TSERC announced regulations on wind and solar forecasting, scheduling regulations, 2018. This is the final regulation and with this Telangana became the sixth, and latest, state to implement Forecasting and Scheduling regulations.

The detailed summary of the regulations is as below:

  • Title of the Regulation: Telangana State Electricity Regulatory Commission (Forecasting, Scheduling, Deviation Settlement and Related Matters for Solar and Wind Generation Sources) Regulations, 2018.The Telangana Forecasting regulation has been finalized within two months of the release of draft regulation.
  • Applicability:
      • From the date of publication in the official gazette.
      • Forecasting tool to be established in three months period.
      • Levy and collection of DSM Charges shall commence after six months from the date of publication in the official gazette.
  • Regulation Applicable on: All grid-connected Wind and Solar Power Generators (except Rooftop PV Solar Power Projects) connected to a pooling substation of the capacity not less than 5 MW irrespective of commissioning date.
  • Deviation Accounting:  The deviation accounting will be carried out based on the Available Capacity:
  • Absolute Error in % =   100 x  Actual Generation – Scheduled Generation  ⁄ Available Capacity (AvC)
  • Point of Forecasting: Pooling Station or STU Feeder where the injection is made.
  • Aggregation: Unlike in Karnataka and AP, Telangana’s order of F&S does not have a provision to provide an aggregated forecast.
  • Role of a QCA:
      • Provide day ahead, week -ahead schedule generator wise and aggregated schedule for each pooling station and the periodic intraday revisions.
      • Coordination with DISCOM/STU/SLDC for metering, data collection, communication/issuance of dispatch/curtailment;
  • Provide day ahead, week- ahead schedule generator wise and aggregated schedule for each pooling station and the periodic intraday revisions.
      • Coordination with DISCOM/STU/SLDC for metering, data collection, communication/issuance of dispatch/curtailment;
      • De-pooling of charges among generators:
      • Commercial settlement of DSM charges on a weekly basis and
      • All other ancillary and incidental matters.
  • Revisions:
      • 16 revisions are permitted for Wind Generators starting from 00:00 Hrs of the day.
      • 9 revisions are permitted for Solar Generators starting from 05.30Hrs of the day.
      • All the revisions are effective from the 4th time-block.
  • Other Key Points:
    • DSM Settlement will be done on a Weekly basis, with Meter data to be provided by SLDC, and verification to be done in coordination with SLDC.
    • After recovering DSM amounts, if there is a gap between the actual commercial impact for the state as a result of deviation of wind and solar generation, such amount will be further recovered from each generator.
    • The wind and solar generator or the QCA will provide payment security to SLDC by the way of BG or revolving LC which will cover the DSM payment for 6 months.
    • De-pooling will be done in proportion to energy injected in each time block by each generator.
    • The QCA will only be forecasting on PSS level. Aggregation to create a virtual pool/aggregate of multiple substations is not allowed. States like A.P and Karnataka have allowed Aggregation in their final regulations.
  • Important differences between intrastate and interstate transactions:
    • The deviations for Inter-State and Intra-State transactions at Pooling Station will be accounted for separately. Separate schedules have to be sent for the interstate to SLDC and RLDC.
    • The Inter-State transactions will be settled on the basis of their scheduled generation and will be considered only if the Inter-state capacity is connected to the STU via the separate feeder.
    • The Generator will pay the Deviation Charges for under or over injection applicable within Telangana in case of deviations in the State DSM Pool.          

 Deviation Charges in case of under or over-injection for sale/supply of power within the State

Sr. No

Absolute Error

DSM Charges Payable to State Pool Account
1 ≤ 15% None
2 >15% but ≤ 25% At Rs. 0.50 per unit
3 >25% but ≤ 35% At Rs. 1 per unit
4 >35% At Rs. 1.50 per unit

Deviation Charges in case of under or over-injection for sale/supply of power outside the State

Inter-state Deviation Charges will follow the same mechanism as defined by CERC (PPA linked). However, the final deviation settlement for Inter-state generators shall be done by SLDC on the basis of deviations and its impact at state periphery.

The TSERC Regulation for Forecasting & Scheduling, 2018 has provided a summary of timelines designating the activities to QCA and SLDC, to be accomplished within the following stipulated duration.

Sr. No. Activity/Milestone Action By Duration (Months)

Telangana releases draft RPO policy for the first time

Telangana State Electricity Regulatory Commission (TSERC) has released draft regulations for the compliance of Renewable Purchase Obligations for the state. These regulations are first of its kind in the state. Before this, the state was following RPO percentages determined by APERC (Andhra Pradesh Electricity Regulatory Commission) through its latest regulation.

 

Comments on these regulations are invited till 9 February 2018.

 

The RPO percentages determined in the regulation are as follows:

In the order, the RPO percentages were only given in terms of total of both solar and non-solar percentages. As per the National Tariff Policy 2016, the solar RPO percentage for states across the country shall reach 8% whereas in the mentioned order, the total RPO percentage (including solar and non-solar is 7.5% ie. 0.5% lower.

The RPO trajectory declared by TSERC as compared to that declared by MoP  for the FY 2018-19 can be seen below:

Telangana Solar Power Policy 2015

The Government of Telangana has recently announced its new solar policy. The new policy will be known as The Telangana Solar Power Policy 2015. The new Policy will come in force from the date of issue and will remain in operation for five (5) years and all the Solar Projects that are commissioned during the operative period will be eligible for the incentives declared under this policy, for a period of ten (10) years from the date of commissioning.

Objectives of the Policy:

The objective of the Policy includes long term energy security, sustainable fuel for energy generation, promoting solar parks in the state and promoting investment in the solar sector. The policy also targets on promoting distributed and decentralized generation and off-grid solar applications.

For availing benefits under this policy, power generated through solar projects has to be consumed within the state.

Applicability of the Policy – This solar policy shall be applicable for the following solar projects set up within the state –

1)      Solar Power Projects:

a) Grid connected solar power projects based on both Photo Voltaic (PV) as well as Solar Thermal technologies

  • Projects set up for sale of power to TSDISCOM’s.
  • Projects set up for sale of power to third parties within the state.

b) Projects set-up for captive generation/ group captive generation (including those funded and owned by developers).

2)      Solar Roof-top Projects (SRPs) (Grid connected and off grid) – This includes projects which are funded and owned by developers.

3)      Off grid applications.

4)      Any other project which is established based on MNRE/GOI Schemes as amended from time to time.

5)      Solar Parks.

 Incentives Offered:

  • Exemption from the payment of Electricity Duty.
  • Deemed Industry Status will be provided.
  • Pollution Clearance.
  • Facilitation of expeditious approvals through single window clearance.
  • Open Access will be allowed.
  • Exemption from Land ceiling Act.
  • Deemed conversion to Non-agricultural land status.
  • 100% refund of VAT/SGST and 100% refund of Stamp Duty for land purchased for setting up solar project and/or solar park.
  • Exemption from wheeling Charges for captive use within the state.
  • Exemption from payment of Cross Subsidy Surcharge for third party sale within the state.
  • Banking for 100% of energy during all 12 months of the year with must run status for Solar Power Projects.
  • Deemed Public Private Partnership (PPP) Status..
  • Non Agriculture Status for the land where Solar Power Projects will be accorded.

The policy also mentions that solar parks will host solar manufacturing, R&D centers, training facilities and financial institutions within the solar parks.

Surprisingly the policy does not talk about the REC and RPO schemes and its benefits. Also it does not give any specific guidelines about the projects to be developed under REC mechanism, which appears to be serious shortcoming.

The policy offers good number of incentives to the project developer, in terms of tax relaxations, must run status, exemptions from various charges, single window clearance etc..

Considering the state, having a huge potential of 20 GW for solar energy generation, the policy might bring substantial investment in the state. Recently the state invited bids for 2000 MW of solar projects. Now as the policy is offering numbers of incentives to the stake holders, the projects in line might see good response from the investors and stake holders.

Analysis of changes in CSS and its impact on Open Access market

Cross-subsidy regime used as a tool to influence the open access market

In this financial year (FY 2015-16), Andhra Pradesh, Telangana and MP suddenly raised cross-subsidy surcharge (CSS) applicable on industrial units significantly. In the case of AP and Telangana last years’ cross-subsidy was nil, but this year its Rs 2.23 and Rs 1.42 respectively. In the case of MP, the cross subsidy increased from Rs 0.48 to Rs 2.16 (an increase of 350%).

An analysis of several states suggests that cross-subsidy is often increased suddenly and substantially. In each of the above cases, the immediate impact will be that third-party transitions will come to a halt, as they will no longer be viable. For example, in MP the revised CSS is 46% (vs 12% last year) of the applicable tariff. In AP and Telangana, its 40% and 25% respectively.

These three states accounted for approximately 20% of the volume on power exchanges as per the market monitoring report from CERC for February (the most recent available). This volume is likely to dip to insignificance thanks to the steep rise in CSS.

Another good example is the case of Haryana. In FY 2013-14, the applicable CSS was Rs 0.53. Next year it was raised to Rs 2.02 (a four-fold increase). As a result, the traded volume between February 2014 and February 2015 has fallen by half (160 MUs and 86 MUs respectively). One must keep in mind that the above volume includes purchase from Discom’s, if any, on which CSS is not applicable. Thus, the actual fall in volume from open access consumer is must larger.

Changes on the horizon

It is clear from the above examples that cross-subsidy is varied by states to influence the open access market.

However, some fundamental changes are on the horizon. The first one pertains to applicability of CSS on renewable energy. One of the amendments proposed to the Electricity Act, 2003 seeks to remove CSS applicability from renewable energy transactions. This will have a significant impact as it will make RE transactions very attractive. One hopes that states will adopt this in its true spirit.

The second change pertains to the way CSS is calculated by the States. The existing National Tariff Policy (NTP) suggests that CSS be calculated as the difference between the top 5% of the incremental power procured by the Discom (this is often proxy for the most expensive power procured) and the applicable tariff. However, this is a very opaque measure – for example, between 2013-14 and 2015-15, the cost of top 5% of the power in MP fell from Rs 5.47 to Rs 4.59 (a fall of 20%), despite increase in overall costs and tariffs.

The amendments to NTP will require the calculations to be done by taking the overall costs (including the cost of regulatory assets, ie losses incurred by the Discom).

 

 

Further, the proposed NTP seeks to limit the CSS to 15% of the applicable tariff in the category. It is noteworthy that till now, NTP has been more recommendatory in nature. For example, it requires that CSS should be brought down progressively to bring it to 20% of the opening level by 2010-11. However, the significant changes done recently clearly indicate that this objective of the policy has not been achieved.

TSERC New CSS for FY 2015-16

Regulatory Commission (TSERC) has calculated the Cross subsidy surcharge to be applicable during FY 15-16. The new CSS will be applicable only for the state of telangana.

There was no CSS applicable in telangana till last FY. The new CSS applicable, will have significant impact on the open access power market.

The telangana solar and wind policy are in waiting, will be announced soon, it will be interesting to see whether CSS will be waived off for RE sources or not.

APERC: Tariff for the Wind & Industrial Waste Power projects

Andhra Pradesh Electricity regulatory Commission (APERC) in its order dated 6th September 2014 has given tariffs for the wind energy generators who have completed 10 years of their commercial operation. The tariff will be applicable to the wind generators of both the states i.e. Andhra Pradesh and Telangana.

The project developers through their submissions requested commission to fix a reasonable tariff as they incurred higher losses due to lower PLF’s achieved. They also requested that in the initial years they paid higher wheeling charges while tariffs were low.

The commission in its order said that as the petitioners were the first movers for the wind generation in the then state of Andhra Pradesh. The PLF’s achieved by petitioners have varied between a range of 6% to 15% against the projected 20% such lowered efficiency has affected the performance of the wind mill generators.

After hearing all the respondent and taking all submissions into consideration the commission fixed single part tariff of Rs.3.37 per unit and said that the tariff should be continued for all these projects till the expiry of the respective PPAs.

In another hearing for fixing the tariff for industrial waste based power projects from 11th year to 20th year of operation, the commission in its order dated 1st September 2014 concluded that the tariff fixed for Biomass based power projects would also be applicable to the Industrial waste based power projects.

The commission in its order dated 19th July 2014 has fixed the fixed cost component for the Biomass based projects in its orderdt.19.07.2014. The details of the tariff are in the table below:

APERC Proposes Draft Amendment for RPO Regulation

Andhra Pradesh Electricity Regulatory Commission (APERC), joint commission for the Andhra Pradesh and Telangana, has proposed separate drafts for the amendment in its Renewable Purchase Obligation (RPO) Regulation 2012, for Andhra Pradesh and Telangana.

The summary of the proposed amendments for the both the states is as below:

  1. According to the proposed draft, the commission proposed to remove the .25% solar purchase obligation for distribution licensee & captive generating plants out of the total of 5% RPO, and has proposed that RPO shall be fulfilled by purchase of any renewable source of energy.
  2. The commission has proposed that the Lapsed Banked Energy (Renewable) as according to Open Access regulation 2006 shall be considered towards the RPO of the distribution licensee.
  3. Consumption from captive co-generation power plant, is exempted for levy of RPO.

The commission has also proposed changes in eligibility of and registration for REC’s, which are highlighted below –

  1. The power generating plant shall be of 1 MW and above capacity for obtaining accreditation from the state agency.
  2. A roof top or ground mounted solar power plant of 100 kW and above, shall be eligible for obtaining RECs for the entire generation from such plant.
  3. The entire electricity generated from Captive Power Plant & Co-Generation Plants based on Renewable Sources of Energy, including self-consumption shall be eligible for issue of REC’s.
  4. In case of pre-mature termination of the power purchase agreement (PPA) with a consumer or DISCOM, a generator will not be eligible for REC’s for three years, starting from the date of termination of the agreement.

The proposed draft will directly affect the solar power generators as the Solar RPO has been merged with Non-solar RPO in the state. In our opinion, since the floor price of solar REC’s are much higher, the obligated entities will not purchase solar REC at all.

In contrast to Tamil Nadu, which has moved to Supreme Court, with a clear objective of implementing Solar Purchase Obligation (SPO) of 6% in the state, APERC does not seem to be in favour of incentivising solar power by having separate RPO status for solar in the two states. In addition to this, the cap of 1 MW on Non-Solar and 100 KW on Solar projects, will only deter smaller projects from coming up in future.

The commission through separate Public notices for Telangana and Andhra Pradesh, has invited the comments and suggestions by 08th September 2014.
