INR 2.67/unit tariff discovered for hybrid wind-solar 1.2 GW tender

The maiden tender for ISTS-connected hybrid wind-solar projects discovered an L1 tariff of INR 2.67/unit recently. The tender postponed six times in the past, due to lack of interest and the capacity was also reduced to 1.2 GW from 1.5 GW previously. The recent tender attracted two bidders who successfully bid for the hybrid projects:

These were the only two firms to participate in the Solar Energy Corporation of India’s (SECI) tender for 1,200 MW of wind-solar hybrid units. The two companies had offered 1,050 MW capacity in total. Due to several issues surfacing in the first tender of its kind, the last date for bid submission had been postponed six times.

The tender saw such a low response due to the low ceiling tariff for the tender. Initially, the ceiling tariff was fixed at INR 2.90/unit but was later reduced to INR 2.60/unit post directions from Ministry of New and Renewable Energy (MNRE). Currently, the market derived tariff for solar found in India is `2.42/unit and for wind energy, the lowest price discovered is Rs 2.43/unit.

The hybrid policy was launched in May,  with an objective to provide a framework for promoting large grid-connected wind and solar PV hybrid system for efficient utilization of transmission infrastructure and land. Along with this, it aims to help reduce the inconsistency in the renewable power generation and in turn achieve better grid stability.

MSEDCL announces RfS for 1000 MW solar projects at INR 2.80/unit ceiling tariff

MSEDCL has announced a Request for Selection (RfS) document for the purchase of 1000 MW power for a long-term basis through a competitive bidding process. The summary of the document is as follows:

  • The project is introduced in order to meet the future power requirements and fulfill the Renewable Purchase Obligation (RPO) of MSEDCL. The successful bidders will be eligible to fiscal incentives like Accelerated Depreciation, concessional customs & excise duties.
  • In case of import of energy in case if intra-state projects the HT industry tariff will be applicable while selling the power to MSEDCL as per the MERC regulations and in case of inter-state projects, all the transmission charges and losses up to delivery point shall be to the account of the successful bidder.

Maharashtra has recently been very active in introducing new schemes for solar PV plants. The state recently tendered 1GW capacity of solar projects to be developed under the Mukhyamantri Saur Krushi Vahini Yojana.


UPERC approves UPNEDA’s petition for fixing the ceiling tariff for 500 MW solar projects

UP New and Renewable Energy Development Agency (UPNEDA) and UP Power Corporation Ltd. (UPPCL) had filed a petition seeking approval for RFP & PPA for procurement of 500 MW Grid-connected solar power through tariff based competitive bidding discovering ceiling tariff-based competitive bidding discovering a ceiling tariff of INR 3.25/unit. UPERC has recently approved the petition and suggested certain changes in the PPA but largely accepting the petition as it is. The key points of the approved petition include:

  • Commercial operation date will be 21 months for projects of capacity less than 250 MW.
  • Commercial operation date will be 24 months for projects of a capacity of more than 250 MW.
  • Upper tariff ceiling will be ₹3.25/kWh if safeguard duty is included.
  • If safeguard duty is not included, upper tariff ceiling will be ₹3.10/kWh.
  • Financial closure must be attained within 365 days of PPA signing.

The changes suggested by the commission are:

  • The document talks about providing 210 days time for the submission of technical Feasibility of connectivity of the plant to the STU substation. The commission suggested that in case the STU is not in a position to provide connectivity to the proposed solar plant due to technical issues, then the PPA should be considered unfruitful without any financial liability on either party.
  • The commission is of the opinion that since the power is always procured in kWh or Million Units (MU) and not in MWh. It should be specified in the PPA that the power will be procured in kWh or MU but the bidding will be done in MWh.


MERC announces generic tariff for various RE sources

Recently the Maharashtra Electricity Regulatory Commission (MERC) announced an order for generic tariff determination of various renewable resources including Solar and Wind. Even after the generic tariff is realized, DISCOMs opt for competitive bidding for tariffs due to the low rates. The details regarding the tariffs for various RE sources is a follows:

Renewable energy sources

Tariff without AD Tariff with AD
Non-Fossil Fuel-Based Cogeneration Projects INR 4.99 _

PSERC Finalizes RE Tariff for FY 15-16

The PSERC (Punjab Electricity Regulatory Commission) on 24th July 2015 has finalized the tariff for Renewable Sources of Energy. The tariff will be applicable for the projects to be commissioned during the year 2015-16. Previously in the May 2015, the commission notified a draft for the determination of the RE tariff and invited comments and suggestion. After considering all the submitted comments and suggestions the commission has come out with the final tariff. The brief details of the tariff finalized are provided in the table below:

The Graph below shows the comparison between the tariffs defined by the PSERC and the Tariff of CERC (Central Electricity Regulatory Commission):

As it can be seen in the graph above that the tariff finalized by PSERC in previous years has remained in line with the CERC and that the commission has done the same for the current financial year also. The tariff for solar energy has reduced by close to 9%, while for wind and small hydro it has been increased by approx. 3.75% and 4.10% respectively.

The more details on the tariff order can be read here.

HPERC Proposes Tariff for Solar Projects

The Himachal Pradesh Electricity Regulatory Commission (HPERC) has notified a draft on 16th June 2015 for the calculation of solar energy tariff in the state. The proposed tariff will be applicable for the projects where PPAs are signed on or before 31.03.2016 and the entire capacities covered by the PPAs are commissioned on or before 31.03.2017.

The details of the proposed tariff are given in the table below:

The proposed tariff by the commission is slightly higher (approx. 1.6%) than the tariff determined by CERC, which can be considered as a promotional move by the commission to encourage the slowly growing sector in the state.

The comments and suggestions on the proposed draft has been invited by the honorable commission, which can be submitted by any interested party or industry stake holders latest by 16th July 2015.

GERC (Gujarat) Proposes Tariff for Solar Projects

The Gujarat Electricity Regulatory Commission (GERC) in a draft notified earlier this month has proposed tariff for the solar projects. The Tariff proposed in the Discussion Paper will be applicable to the projects commission during July 1, 2015 to March 31, 2018. The commission through a separate public notice has invited comments and suggestions from the interested stake holders by 22nd June 2015.

The details of the tariffs proposed are in the table below:

Below is the graph for comparison between tariffs of CERC and GERC for previous years:

Wheeling Charges:

  • For Injection at 66 kV voltage level and above, transmission charges as applicable to normal open-access customers and transmission and wheeling loss @ 7% of the energy fed into the grid.
  • For Injection at 11 kV or above and below 66 kV, wheeling in the area of the distribution licensee will be allowed on payment of distribution loss @ 3% of the energy fed in to the grid. In the other case of wheeling within the State but in the area of a different distribution licensee will be allowed on payment of transmission charges as applicable to normal Open-Access Customers and transmission and distribution loss @ 10% of the energy fed in to the grid.

Cross subsidy Charges: As a promotional measure for solar power no cross-subsidy surcharges would be levied in case of third-party sale.

It is worth noticing that GERC had calculated its tariffs back in 2012 for coming years I.e. FY 13, FY14 & FY 15, while CERC revises its tariffs every year. The difference visible between tariffs of CERC and GERC for previous years is because the GERC hasn’t revised its tariff after 2012 and it is that period during which the capital cost of the solar modules fell drastically and so the difference didn’t reflect on the tariffs of GERC as it wasn’t revised.

Now the GERC has proposed new tariff which is quite lower (approx. 5.5%) than the tariff finalized by the CERC. A public hearing on the matter will take place on 29th June 2015.

Rajasthan Finalizes Wind Tariff for FY 15-16

The Rajasthan Electricity Regulatory Commission (RERC) has finalized the tariff for wind energy projects; it will be applicable for FY 15-16. Earlier the commission notified a draft and invited comments and suggestions from the stake holders.  The details of the tariff finalized are given in the table below:

Below are the graph for tariffs finalized by RERC and CERC and a comparison between them.

The Commission (RERC) in its order has reduced the tariff by 3.23% compared to previous year, which appears to be inspired by tariff of CERC (reduced by 2.02%). In the previous years the tariff for wind energy in Rajasthan was one of the highest in the country, and was an attractive destination for industry.
