CERC Staff Paper
“ Developing a Common Platform for Electricity
Trading in the Country”: our comments
PTC India Ltd.
General





CERC’s own research and findings/ a timely effort on the subject
Draws reference from power markets in countries such as Nordic countries,
USA, UK and South Africa
Power Exchange (PX) is stated to provide a trading platform that is efficient,
equitable and transparent
PX to meet day-ahead power requirements, besides the existing bilateral
trading through short term contracts and UI mechanism
Recommends
 setting up of a National Power Exchange
 a cautious approach due to prevailing power deficit
Thinking ahead - to create a roadmap for the
future with a view to organize competition!

Trading – the current scenario






EA 2003 recognizes trading as a licensed activity
Staff paper recognizes that electricity trading is essential for meeting peak
demand and for overall resources optimization
Bi-lateral physical trade: Volumes are about 3% of electricity generation
Today 22 entities have trading licensees
 Few active, many dormant
Buying and selling power remain a voluntary , transparent process
The cost of traded power in our country, to a large extent, reflects the value
accepted by the market
Better price discovery requires larger volumes, more liquidity!!!

Trading and PX

Electricity Trading market is still in a nascent stage

Rising cost of traded power –legitimate market signals in a deficit situation
 Voluntary, not mandatory
 Utilities exercise load-shedding/power cuts

A need for promoting both bi-lateral trading and Power Exchange

Policies and regulations need to ensure non-discrimination between PX
and Bilateral Trades

Power Exchange: A Trading Licensee? (Para 6.4.2)

The staff paper tries to equate Power Exchange with a trading licensee

PX does not trade at its own behalf, it does not take positions; it does not
invest its capital in transactions.

Hence, in our view, granting of trading licence to PX may not be a proper
proposition..
5
Promoters of Power Exchange (Para 6.4.3)

The proposed Power Exchange at national level is envisaged to be a
separate entity promoted by generators, trading licencees, distribution
licencees, CTU, banks/ FIs.

Since the PX is a voluntary market place, perception of impartially, neutrality
and transparency are important ingredients.

CTU among promoters will facilitate better harmony between market
operator and system operator
6
Membership of PX not to be limited to grid connected
entities (Para 6.4.4) (1)

The PX membership, which qualifies a market player to participate in the
bidding, has been limited to grid connected entities

This means electricity traders would not be eligible to participate in the
bidding for day ahead power, which is contrary to the objective of equitable
trading stated in para 1.3 as well as para 4.1.1.

Electricity Act 2003 does not restrict trading to be carried out by grid
connected entities.

Many grid connected entities, not financially solvent , may still intend to act
through intermediaries to avail the PX services. They will be denied the
benefits of PX.
7
Membership of PX not to be limited to grid connected
entities (Para 6.4.4) (2)

Traders can increase the market liquidity

For example, In Nord Pool there are as many as 400 members against 70
grid connected users.

Thus, there should be no restriction on market players as long as they are
financially solvent and have physical contracts to back the bid
8
Trading Licencees should have Primary Membership
in the PX (Para 6.4.5)

Trading Licencees have been given a secondary position as associate
members, although they are eligible to be the promoters of Power
Exchange.

This is a discriminatory provision and must be removed.

Trading Licencees should be eligible both as promoters of PX as well as for
primary membership.

In Nord Pool Spot, there are ‘Direct participants’ as well as ‘Traders’
9
Trading Licencees should be allowed to bid from the
short term capacity (Para 6.4.5)

The Power Exchange is for day-ahead power, which is a short term
requirement. Therefore, a trader has the option to tie up the capacity for day
ahead at a competitive price through a short term contract

For example, in Nord Pool, if one has a day-ahead physical contract and
wants to bid this into the day-ahead market, one is free to do so and there is
no differentiation between a long term and a short term contract.

Thus traders must be allowed to bid in the day-ahead market from the short
term or long term capacity as the case may be.
10
Restrictions on traders to aggregate supply from more than
two sources to be removed (Para 6.4.5)

Para 6.4.5 stipulates that trading licencees should not be allowed to aggregate from 2
or more sources. There seems to be no rationale behind this proposition.

In Nord Pool, the traders can give bids from aggregated sources, but the aggregated
sources have to be allocated to the same spot bid area. If the sources are in different
bid areas the sources can not be aggregated.

PX generally deals with standard electricity products. Aggregation is one of the most
important value propositions the traders bring to the market.

If aggregation is not allowed freely ( except meeting the condition that such
aggregation should be in one electricity region/price area only), it may lead to serious
liquidity problems and will be detrimental to the growth of the market.
11
Pre-Assignment of Transmission Corridors to PX –
A Discriminatory Step (Para 5.2)

The Staff Paper introduces a separate category of transmission customers
and seeks pre-assigned transmission capacity on inter-regional corridor for
PX

Both these requirements are contrary to the provisions of non-discriminatory
open access to transmission system in the Electricity Act 2003 and CERC’s
Regulations on Open Access to transmission system

Further Regulation 6 clearly specifies, “Within a category (long term or short
term) there shall be no discrimination

An equitable method seems to be that in case of congestion, the available
transmission capacity of inter-regional link is shared between bilateral
contracts and that through Power Exchange pro-rata
Main problem is limited surplus capacity – redundancy
needs to be improved
12
Discriminatory Provisions for PX on Transmission
Charges (Para 5.3)





There are a number of discriminatory provisions related to transmission
charges that favour PX transactions over bilateral short term transactions.
For example:(a) One transmission charge for bidding through Power Exchange
(b) Transmission charges for PX shall be on energy (MWh) basis while that
for bilateral contracts will be on MW/day basis;
(c) Transmission charges shall be as per implemented schedule for PX
whereas for bilateral transactions the charges shall be as per contracted
capacity;
(d) It also seems that operating charges of RLDCs and SLDCs have been
waived for transaction through PX, whereas bilateral transactions have to
bear such operational charges
13
Transmission Pricing Regime –Need for review

Equitable sharing of transmission charges and losses –a challenge

Present method of price discovery does not take into account the
transmission charges and losses

Asymmetry between the buyers and sellers bid prices and quantity

In Nord Pool this issue has been addressed by adopting Point-ofConnection Tariff and Transmission charges and losses are bought by TSO

If PX is to be set up, transmission tariff is to be reviewed
14
Specific Comments

A National Power Exchange preferable over Regional PX-subject to viability
of investment. (Para 4.2.2)

Decentralized dispatch concept is preferable over Centralized dispatch

Market liquidity is the most critical factor and necessary environment is to
be created that leads to more market participants, more volumes and
freeing of large capacity tied up in long term bi-laterals

PX should be able to gradually capture the current day-ahead scheduling of
ISGS, the upcoming generation capacities and also cross-border resources.
15
Specific Comments

Voluntary PX versus Mandatory (Para 4.2.3)
In principle, the participation in PX is to be voluntary as is the case in many markets.
Since power is a concurrent subject in our country and states exercise autonomy in
system operation, voluntary PX would have more chances of success.

Single side bidding versus two side bidding (Para 4.2.4)
The principle of two-sided bidding by suppliers and buyers resulting in single uniform
market price discovered by aggregate supply and aggregate demand quantities and
prices could be adopted in our case. Efficacy of participants bidding on marginal
costs seems doubtful in our case. Transmission Pricing and losses need to address
the issue of inequitable sharing of such charges and losses
16
Specific Comments

Block Bidding Versus Multi-part bidding ( 4.2.9)
Block bidding has been preferred due to simplicity but multi-part bidding would be
more appropriate for merchant plants in which in addition to price quantity bids, he
can also quote start- up charges and minimum load charges for optimization by the
PX.

Varying bid price caps (Para 6.1.3)
Price caps distort the market mechanism and tend to move prices towards the caps.
No voluntary, liquid market use price caps. Varying price caps will completely defeat
the purpose of the Power Exchange.

Organizing Electricity Market
•
A challenging task
•
Requires
– Detailed study
– Preparation and
– Investment
•
EA 2003 gives directions for taking measures conducive to
– development of electricity industry,
– promoting competition therein, and
– protecting interest of consumers
•
PX need to co-exist with bilateral trading, UI being non-firm should be for
balancing power only
•
Development to be inclusive!
Traders should not be discriminated!
