Policy and Regulatory
Maharashtra Wind Zone Classification Procedure
In recent Wind Power Tariff Orders, Maharashtra Electricity Regulatory Commission (MERC)
has come out with wind power tariff structure for different wind zones in the state. In these
orders, MERC has segregated the sites into 4 different zones based on the mean annual
wind power density (WPD) in those areas:
Maharashtra State Electricity Distribution Co. Ltd. (MESDCL) had raised some issues on the
manner in which zoning of different areas was to be done. MSEDCL had also been refusing
execution of the long term Power Purchase Agreements (PPAs) as per the MERC Order in
effect. This had led to a lot of confusion and resentment amongst the investors, lenders and
even the manufacturers of wind turbine generators. The outcome was a significant delay in
investments in windfarm development in the state. Though, it has taken time, but, the
Maharashtra Energy Development Agency (MEDA) has now come out with a clear
procedure for classification of wind zones. The highlights of the zone wise classification are:
Ÿ The mean annual WPD at 50 meter at the reference wind mast, declared by Centre for
Wind Energy Technologies (C-WET) under the Ministry of New & Renewable Energy
(MNRE) or MEDA programme or data vetted by C-WET location shall be considered to be
the annual mean WPD for the effective area of 10 km radial distance from the location of
the reference wind mast.
Ÿ If a Wind Power Project (WPP) falls within the effective areas of two different wind
masts having different values of annual mean WPD, then the annual mean WPD of the
nearest wind mast shall be considered for that WPP.
Ÿ For an upcoming WPP, within the effective area, if 50% or more than 50% of the
proposed WTG location co-ordinates are falling above or below 60 m elevation
difference with reference to the mean sea level (MSL) of the reference wind mast, then
investor/developer shall approach C-WET to obtain project specific annual mean WPD
report either on MEDA's advice or permission. While signing Energy Purchase
Agreement (EPA) with the distribution licensee, developer/investor shall have to submit
letter issued by MEDA for wind zone classification.

Introduction of Cross Subsidy Surcharge in Maharashtra
Earlier in 2006, to promote Open Access (OA), MERC came with an order determining Cross
Subsidy Surcharge (CSS) as Zero for OA Consumers from September 2006 to September
2011. Later in August 2010, MSEDCL had filed a Petition with MERC seeking review of the
aforesaid order in light of achievement of the same (i.e. to match the electricity demand in
the State through OA.
MERC has decided to re-determine the CSS due to the change in the current power
scenario. The CSS has been computed for Open Access transactions for various consumer
categories based on their voltage levels. The range of applicable CSS is Rs. 0.21/unit to Rs.
2.81/unit for different DISCOMs (R-Infra, MSEDCL, BEST, Tata Power), for different
categories of consumers (industrial, commercial etc), connected at different feeders
(express/non-express) at different voltage levels (above/below 66 kV).
CSS applicable to open access transactions from Renewable Energy Sources has been
fixed at 25% of the applicable CSS of the respective consumer category. MERC has fixed a
discounted CSS in order to promote generation from Renewable Energy sources, which is
in line with the objectives of EA 2003
KREDL Notification for Wind Project Developers
Recently, MNRE has done away with the criteria for Wind Power Density (WPD) for
installation of commercial WPPs in India. In contrast of this, KREDL has decided, not to insist
on this parameter to approve DPRs. However, to ensure use of higher efficiency WTGs only,
KREDL has mandated minimum generation of 20% CUF per WTG in the agreements with
developers/ manufacturers. The clause shall include removal of those WTGs (<20% PLF) on
the cost of manufacturers/developers.
Rajasthan DISCOMs have increased tariff for HT consumers
Rajasthan DISCOMs have filed ARR in RERC for the year 2011-12 and revised the applicable
tariff for industrial and commercial consumers. Following are the new tariff for various
categories:
Due to ~ 100 paisa/kWh hike in tariff, the investors who have already installed WPPs and
those who are planning to install WPPs for captive use, will get higher benefit as their cost of
power remain insulated for such steep hike state tariff.

The current qualification criteria for installation of WTGs in India require a certification from
C-WET which is a time taking process even in cases wherein a certificate from
Internationally Recognised Agency is available. This has in-turn restricted certain better
WTG models and technology to be used in India.
To give a boost to wind power development in India by creating the environment that
promotes healthy business, ensures safety standards and encourages technological
growth, MNRE has issued new draft guidelines for installation of wind turbine models in thIndia and invited comments/views/suggestions on the same by 29 September 2011.
Major highlights of these guidelines are:
Ÿ Any new WTGs to be installed in India must possess a valid type certificate from an
internationally accredited certification agency and fully comply with IEGC 2010.
Ÿ Manufacturers can install up to 15 MW of a specific turbine model in India to test its
performance in India. To sell any such model in India, they will be required to establish
manufacturing base in the Country.
Ÿ The self-certification guidelines for installation of WTGs, which allows installation of
non-certified machines, have been discontinued with immediate effect.
This guideline will cover all such machines that have already been approved under the
RLMM scheme, but not yet installed. However, self-certified machines approved under
the RLMM scheme and installed will be subject to guidelines issued in December 2009
and January 2010 that required submission of the documents related to type certificate
within the committed timeframe and other requirements.
Ÿ The guidelines also specify four international certification programmes that will be
accepted in addition to the revised TAPS-2000 programme of C-WET. The certification
clauses will accelerate capacity addition by de-clogging C-WET's pipeline. The guidelines thare applicable from 1st December 2011 in the run-up to the 12 Five Year Plan (2012-
17), and from the same day the RLMM Committee will stand dissolved.
The following certification schemes will be recognised when an accredited certifying body
carries out certification:
Ÿ IEC Certification Scheme
Ÿ Germanisher Loyds Certification Scheme
Ÿ The Danish Certification Scheme
Ÿ The Dutch Certification Scheme
As per addendum to Main List (RLMM) of Wind Turbines in India dated 22.09.2011,
following WTGs have been added viz. Kenersys K100 - 2.5 MW, Global L82 - 2.0 MW, Suzlon
S95, S97 - 2.1 MW & S88 - 2.25 MW.

In FY 12 H1, ~ 1445 MW of Wind capacities have been commissioned. In view of possibility stthat the accelerated depreciation benefit may not be available post 31 March 2012 a good
portion of this capacity may have come from the accelerated depreciation seekers.
Similarly, for IPPs also, as per current policy GBI is available for projects commissioned by st31 March 2012 only. These two can be the key drivers for the huge investment this year. We
expect that the total capacity to be commissioned this year shall be in the range of 2500 -
3000 MW.

Calculation of Equilibrium Price (EP) and Volume for RECs at IEX
A matching of the buy and sell bids will take place only if there are crossing prices (Buy Price
>= Sell Price). Accordingly, the EP is determined as per following criteria:
Ÿ EP will be the price at which there is Maximum Tradable Volume (MTV).
Ÿ If there is more than one price with equal value for MTV, the price that leaves the least
volume untraded at its level (minimum unbalance) is chosen as EP.
In price determination process, at every candidate price level (CPL), the volume is
cumulated and the difference between cumulative buy and cumulative sell is calculated.
This gives two values at every CPLs:
Ÿ Tradable Volume (minimum of cumulative buy and cumulative sell)
Ÿ Unbalance (Difference of cumulative buy and cumulative sell; positive, negative or zero.
Following four rules are for calculating EP:
Rule 1: If a CPL with maximum tradable volume exists, this price is an EP. This rule gives one
or more price levels:
Ÿ If the maximum tradable volume is zero (no crossing prices), no EP is determined.
Ÿ If there is only one price level, this is the EP.
Ÿ If there are multiple levels, rule 2 is applied.
Rule 2: If there are several price levels for maximum tradable volume, the levels with
minimum Unbalance are CPLs. This rule gives us one or more price levels:
Ÿ If there is only one price level, this is the EP.
Ÿ If there are multiple price levels, and the unbalance is not zero, rule 3 is applied.
Ÿ If there are multiple price levels, and the unbalance is zero, rule 4 is applied.
Rule 3a: If the sign(+/-) of unbalance is same for all CPLs, the price closest to the price at
which sign of unbalance has changed (from positive to negative or negative to
positive, as the case may be) , is chosen as EP.
Rule 3b:If the unbalances at CPLs have different signs, the highest CPL with positive
unbalance and the lowest CPL with negative unbalance are identified. The EP is
then chosen randomly between these two.
Rule 4: If there are two CPLs with unbalance = 0, then one of them is chosen randomly as EP.
For a better understanding, we may refer the following example:
In this graph, there are 3 different buy bids and 3 different sell bids.

Enabling High Efficiency and Reliable Wind Power Projects
A is the buyer who is willing to buy 1000 REC at any price =< Rs 3900/REC, B is willing to buy
6000 REC at any price =< Rs 2300/REC and C is willing to buy 2000 REC at a price of
Rs1700/REC. Whereas D is the seller who is willing to sell 1000 RECs at any price >= Rs
1500/REC, E is willing to sell 2000 RECs at any price >= Rs 1700/REC and F is willing to sell
3000 RECs at any price >= Rs 2000/REC.
Now Rs 2200/REC is the price level for maximum tradable volume and minimum imbalance
so equilibrium volume shall be 6000 RECs at an equilibrium price of Rs 2300/REC.
From the above graph it can clearly be said that during the last one year, most of the time,
except 1-2 month, short term market price of electricity in bilateral arrangement is higher
than that at power exchanges. This analysis includes only inter-State transactions.
Electricity price in bilateral arrangements, in year 2011 is lesser than price in year 2010
showing a decrease in prices. The ratio of electricity traded on power exchanges to that of
total short term bilateral trades has increased from ~22% in 2009-10 to ~36% in 2010-11.
