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.”

 

Tamil Nadu announces final solar energy policy 2019

Tamil Nadu Energy Development Agency announced the final Tamil Nadu solar energy policy 2019. The policy intends to include solar energy in demand side management, energy conservation, energy efficiency, smart grids etc.the policy also talks about encouraging public-private partnerships, joint ventures etc. to accelerate solar energy projects, manufacturing facilities, and R&D.

  • Tamil Nadu intends to have an installed capacity of 9,000 MW by 2023, of which 40% is intended to come from rooftop solar plants.
  • The policy is applicable to both utility & consumer category systems.

Utility category: where the objective is sales of solar energy to a distribution licensee or a third party or self-consumption at a remote location (wheeling). For these systems, the grid connection is through a dedicated gross metering interface.

Consumer category systems: where the objective is self-consumption of solar energy and export of surplus energy to the grid. For these systems, the grid connection is through a consumer service connection of a distribution licensee.

  • The tariffs will be based on market-based competitive bidding & net feed-in tariff decided by TNERC time to time.
  • TNERC may introduce Time of Day (TOD) solar energy Feed-in tariffs to encourage solar energy producers & solar energy storage operators to feed energy into the grid when the energy demand is high.

Types of solar plant models:

  • Upfront ownership: The purchaser of the solar system pays the supplier for the capital cost and takes ownership of the solar system.
  • Deferred ownership: The solar system is installed and operated by the supplier. The purchaser makes system performance-based payments to the supplier or leases the system from the supplier. System ownership is transferred to the purchaser on a mutually agreed date or is triggered by a mutually agreed event.

Incentives:

  • Rooftop solar plants will be exempted from electricity-tax for two years from the date of the policy.
  • Solar energy injected into the grid of the distribution licensee by solar energy producers who have no renewable energy purchase obligations (non-obligated entities), including the solar energy export by non-obligated electricity consumers, can be claimed by the distribution licensee towards the fulfillment of their Renewable Energy Purchase Obligations (RPO).
  • The government will provide land for the development of solar system manufacturing components in the state, components like solar cells, inverters, mounting structures, and batteries etc.

Grid connectivity and Energy evacuation:

  • For consumer category solar PV systems, the system capacity at the service connection point shall not exceed 100% of the sanctioned load of the service connection.
  • For high tension consumers, open access regulations of TNERC will apply, subject to the conditions imposed by SLDC. However, wheeling for less than 1 MW shall not be allowed.

TEDA and TANGEDCO will be the leading government agencies in implementing the new solar policy in the state of Tamil Nadu.

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).
