New Enhanced Dispatch Arrangement Rules (Ver 1.0)

1.0 Introduction

1.1 The New Enhanced Dispatch Arrangement Rules (NEDA Rules) provides guidelines on

the operation of the New Enhanced Dispatch Arrangement (NEDA) to enhance

competition and cost efficiency of the Single Buyer market. It also prescribes the

obligations and rights of the Participants.

The NEDA Rules together with the Single Buyer Rules and the Grid Codes will ensure

equitable, fair, coordinated and cost efficient operation of the Single Buyer market.

The NEDA Rules is supplementary to the Single Buyer Rules and should be read in

conjunction with the Single Buyer Rules.

1.2 Unless the context otherwise requires, words and phrases used in the NEDA Rules

shall have the same meaning as defined in the Single Buyer Rules.

1.3 It is recognised that some Generators have existing commercial agreements with the

Grid Owner, the Network Operator, the Nominated Coal Supplier, the Nominated Gas

Supplier or other parties. Nothing contained in this NEDA Rules is intended to modify

the parties’ rights and obligations under these agreements. In the event of any

conflict, the existing commercial agreements take precedence only to the extent that

it does not

(i) affect the security and safety of the Grid System, or

(ii) seek to impose any liability on the Single Buyer and Grid System Operator

in the discharge of their obligations under the Single Buyer Rules, the

NEDA Rules and the Grid Code in accordance with the terms thereof.

2.0 Objectives of NEDA

The main objectives of NEDA are as follows:

Enhance cost efficiency in generation through short-run competition;

Enable energy efficient options, particularly the use of efficient technology such

as co-generation;

Provide opportunity for non-PPA/SLA Generators such as co-generators,

renewable energy generators/producers, embedded generators and expired

Page 4: New Enhanced Dispatch Arrangement Rules rules v1.1.pdf · benefits of the electricity supply industry. ... TNB and all current PPA/SLA Generators ... application form for registration

2

PPA/SLA Generators to operate as Merchant Generators to sell energy to the

Single Buyer;

Enable expired PPA/SLA Generators to enhance their business options by

maximizing the use of the existing facilities in a cost efficient manner for the

benefits of the electricity supply industry.

2.2 In addition, this will also incentivize non-PPA/SLA Generators to provide term based

reserve capacity for short-term system requirements at competitive prices.

3.0 Principles of NEDA

3.1 The current cost-based bidding system is complemented by introducing an optional

price-based bidding. This will enhance competition in generation dispatch and result in

more competitive energy prices.

The main features of NEDA are:

Generators with PPA/SLA can offer optional reduced heat rates and variable

operating rates (VOR), alternative to the rates in the PPA/SLA. If dispatched, they

will be paid the energy payment using the lower of the PPA/SLA or optional offer

heat rates and VOR;

Merchant Generators with capacity more than 10MW (non-PPA/SLA Generators

such as expired PPA/SLA Generators, co-generators , renewable energy

generators/producers and embedded generators) can offer to sell energy to the

Single Buyer. If dispatched, they will be paid at Price as Bid, subject to a cap price

which is the variable cost of the most expensive PPA/SLA Generating Unit

available for dispatch to meet demand in each trading interval;

Merchant Generators with small co-generation or renewable energy

generation/production of 100kW to 10MW (hereinafter referred to as Small Co-

gen and RE Generators) can sell energy to the Distributor. The settlement will be

on monthly basis based on the monthly average of the daily average of the half

hourly System Marginal Price (SMP) of the Single Buyer market;

No major change to current generation scheduling and dispatch arrangements;

No violation to current PPA/SLA as the PPA/SLA Generators can choose whether

to submit the optional offers or not;

3.2 The Single Buyer shall schedule the dispatch of the Generating Units based on a Least

Cost Dispatch Scheduling Methodology such that the lowest marginal cost Generating

Unit is forecast to be dispatched first to meet demand followed by the next lowest

marginal cost Generating Unit until all demand is met as prescribed in the Single Buyer

Page 5: New Enhanced Dispatch Arrangement Rules rules v1.1.pdf · benefits of the electricity supply industry. ... TNB and all current PPA/SLA Generators ... application form for registration

3

Rules. The marginal cost of generation shall comprise all payments, which vary with

the amount of electricity procured, that are made by the Single Buyer to the

Generators, pursuant to Generator Contracts, Daily Heat Rate and Variable Operating

Rate Bids or Daily Price Bids.

4.0 Registration of Participants and Submission of Information

4.1 To participate in the Single Buyer market, Generators shall possess appropriate

generation licenses issued by the Energy Commission (ST) and shall register with ST as

Participants under the Single Buyer Rules.

4.2 The Single Buyer, the Grid System Operator, TNB and all current PPA/SLA Generators

are incumbent Participants of the Single Buyer market. Nevertheless, they shall

register with ST as Participants in compliance with the Single Buyer Rules.

4.3 Generators shall register their Generating Units as Centrally Dispatched Generating

Units or Non Centrally Dispatched Generating Unit, unless approved otherwise by ST.

Information to be submitted for registration includes but not limited to the following:

a) Technical and performance data of the Generating Units as depicted in the

application form for registration in Appendix D. These data are in addition to the

information required to be submitted to the Grid System Operator and

Distributors under the Malaysian Grid Code and Malaysian Distribution Code:

b) Default Price Bid

For PPA/SLA Generators, the default heat rates and VOR are the rates in

the PPAs/SLAs;

Merchant Generators, except Small Co-gen and RE Generators shall submit

one price;

Expired PPA Generator who’s gas usage is under the power sector

allocation shall submit three(3) prices: indigenous piped gas, LNG and

distillate. In addition, they shall also submit default heat rates. The default

heat rates will be used for adjustment of payment if the price of the fuel

used for dispatch is different from that given by the Single Buyer for bidding

purpose.

c) start up cost

d) generation usage plan

e) other information as required by ST

4.4 For Merchant Generators, the Default Price Bid shall contain a set of up to 10 price-

quantity pair half hourly bids representing the prices a Merchant Generator is

prepared to sell energy to the market from one of its Generating Units. The bid can

contain from 1 to 7 sets of price-quantity pairs representing default bids from Sunday

to Saturday respectively. The default set of price-quantity pairs will be used whenever

the Merchant Generator declares its Generating Unit is available to generate but has

not submitted a daily price bid for the Generating Unit.

4.5 Participants, other than Small Co-gen and RE Generators, shall comply with the Single

Buyer Rules and submit information to the Single Buyer for preparation of generation

schedules i.e. three-month ahead schedule, week-ahead schedule and day-ahead

schedule. The information to be submitted includes:

available generation declaration for each of its Generating Units for each half-

hourly period for the Single Buyer to prepare the day ahead and week ahead

schedules;

Day ahead half-hourly tranche bids (heat rate and/or VOR for PPA/SLA

Generators and price-quantity pairs for Merchant Generators). The Default Price

Bid will be used for scheduling if no day-ahead bid is submitted.

4.6 Participants shall comply with the Malaysian Grid Code (the Grid Code) and the

Malaysian Distribution Code (the Distribution Code), where relevant, unless otherwise

exempted by ST.

5.0 Submission of Offers

5.1. Generators Subject to Central Dispatch

Generators can submit to the Single Buyer the daily Submission of Offer by 10.00am

on the day before with Form A1(Appendix A1) or Form A2(Appendix A2), whichever

relevant. The offers shall be submitted together with the Daily Availability

Declaration Form(Appendix B) by an authorized person to the Single Buyer in writing

(or by such electronic data transmission facilities as have been agreed with the Single

Buyer) according to the procedure and timeline for the submission of Daily Availability

Declaration prescribed in the Grid Code and the Single Buyer Rules. On receiving the

Submission of Offer from a Generator, the Single Buyer shall acknowledge receipt of

the submission. The Single Buyer shall prepare, finalise, revised and send the Day

Ahead Dispatch Schedule to the Generators according to the timeline in the Single

Buyer Rules as depicted in the Timeline for Day Ahead Dispatch Schedule in Appendix

C. It is the responsibility of a Generator to ensure that its submission is properly

5

transmitted to and received by the Single Buyer and to communicate, if necessary,

with the Single Buyer on the status of its submission.

The offer can be for one or more Generating Units for the 48 half-hourly tranches and

shall consist of not more than 10 price-quantity pairs for each tranche(for (Merchant

Generators)/price-heat rate and/VOR pairs (for PPA/SLA Generators) as follows:

PPA/SLA Generators may offer optional heat rate and/or VOR for their Generating

Units. The optional heat rate and VOR offered shall not be higher than that in the

PPA/SLA. If dispatched, they will be paid the energy payment using the lower of

the PPA/SLA or optional offer heat rates & VOR;

Merchant generators with capacity more than 30MW on central dispatch can

submit price-quantity pair bids based on their own fuel arrangements. If

dispatched, they will be paid at Price as Bid, subject to a price cap;

Expired PPA Generators whose gas usage is under the power sector allocation

can submit price-quantity pair bids based on the composite gas price for power

sector (indigenous gas and LNG) given by the Single Buyer for bidding purpose.

If dispatched, they will be paid at Price as Bid. However, if the price of the fuel

used for dispatch is different from that given by the Single Buyer for bidding, the

payment will be adjusted according to the declared heat rates.

5.2 Co-generation and Renewable Energy Generation/Production not on Central Dispatch

Merchant Generators with co-generation or renewable energy generation/production

which are either connected to the Grid System or Distribution Network and not

subject to central dispatch can participate in NEDA under the following arrangements:

a) A Generator with capacity more than 10MW but not exceeding 30MW can

offer to sell energy to the Single Buyer on self dispatch. The Generator can

submit offer of price-quantity pair bids with Form A2 for Submission of Offer

and Form B for Day Ahead Declaration to the Single Buyer according to the

same procedure and timeline as for Generators on central dispatch described

in clause 5.1 above. The Single Buyer shall inform the Generator in writing (or

by such electronic data transmission facilities as have been agreed) whether its

offer is accepted or not; and if accepted, the tranches of quantity-price pair

accepted and the schedule of dispatch. In scheduling the dispatch, the Single

Buyer shall take into consideration any limitation on the performance of the

plant such as ramp rates, start up time, run down time, minimum up time (in

operation), minimum down time (shutdown) etc. . The Generator can be on

self dispatch based on the quantity and dispatch schedule issued by the Single

Buyer unless instructed otherwise by the Grid System Operator or Distributor

Page 8: New Enhanced Dispatch Arrangement Rules rules v1.1.pdf · benefits of the electricity supply industry. ... TNB and all current PPA/SLA Generators ... application form for registration

6

due to system constrain or system security reasons. However, if the Generator

is unable to dispatch its plants based on the schedule provided by the Single

Buyer, it should inform the Single Buyer as soon as it is practicable and by

means as required by the Single Buyer. The minimum offer is 1.0MWh for

each half-hourly bid.

b) A Small Co-gen and RE Generators with capacity of 100kW up to 10MW can

supply energy to the Distribution Network based on the capacity offered with

Form A3 and Day Ahead Declaration Form B submitted to the local Distributor

on day ahead. The Generator can be on self dispatch based on its offer to the

Distributor unless instructed otherwise by the Distributor due to system

constrain or system security reasons. The settlement will be on monthly basis.

The payment for the energy supplied in a month will be based on the monthly

average of the daily average of the half-hourly System Marginal Price.

Minimum offer is 50kW.

6.0 Fuel Management

6.1 For PPA/SLA Generators, no change to the fuel arrangement as provided for under the PPA

and GSA.

6.2 Merchant Generators with co-generation and embedded generation shall manage

their own fuel requirements.

6.3 Expired PPA Generators participating as Merchant Generators shall secure their own

fuel requirements. However if the power is supplying solely to the power sector and

under the dispatch of the Single Buyer, the gas required for generation will be

covered under the power sector gas allocation and pricing system.

7.0 Purchase Price

7.1 PPA/SLA Generators, if dispatched, will be paid at lower of the PPA/SLA heat rates and

VOR or optional offer heat rates and/or VOR

7.2 A Merchant Generator other than a Small Co-gen and RE Generators, if dispatched,

will be paid at Price as Bid subject to a price cap. However for expired PPA Generator

whose gas usage is under the power sector allocation, payment will be adjusted

based on the default heat rates if the price of the fuel used for dispatch is different

from that given by the Single Buyer for bidding.

7.3 Small Co-gen and RE Generators on self dispatch to the local Distribution Network will

be paid by the Distributor on monthly basis. The purchase price for the total energy

Page 9: New Enhanced Dispatch Arrangement Rules rules v1.1.pdf · benefits of the electricity supply industry. ... TNB and all current PPA/SLA Generators ... application form for registration

7

supplied in a month will be based on the average monthly of the average daily of the

half-hourly System Marginal Price for that month.

7.4 A Merchant Generator on central dispatch if instructed by the Grid System Operator

to dispatch, will be paid the start up cost for each successful start up based on the

rate submitted by the Merchant Generator on registration as a Participant, unless a

notice to cancel the dispatch has been issued and acknowledged receipt by the

Generator prior to the preparation for the start up.

7.5 Merchant Generators on self dispatch are not entitled for any separate payment on

start up cost.

7.6 The price of Merchant Generators will be capped at the variable cost (fuel plus VOR)

of the most expensive available PPA/SLA Generating Unit meeting the demand; or if

such Generating Unit is not available, the prevailing purchase price from the

interconnectors(Singapore or Thailand).

7.7 The procedures and timeline for settlement of payments other than for Small Co-gen

and RE Generators, shall be as described in Chapter 14 of the Single Buyer Rules. The

settlement for Small Co-gen and RE Generators will be on monthly basis.

8.0 Failure to Dispatch and Compensation

8.1 If a Merchant Generator declares available for the Day Ahead Schedule but fails to

dispatch or dispatches at a lower load than in the dispatch instruction, the Generator

shall pay the Single Buyer the incremental cost of replacement generation to meet

resulting energy shortfall.

8.2 The Merchant Generator may make a compensation claim in the event that the Grid

System Operator has issued a dispatch instruction to the Merchant Generator for the

dispatch of a Generating Unit but the Generating Unit is not dispatched or dispatched

at less than 70% of the load that has been instructed, provided that the change to the

dispatch has resulted in actual costs being borne by the Generator. Where the claim is

deemed valid by the Single Buyer, the Single Buyer shall pay compensation to the

Generator to cover the direct loss incurred by the Generator for the tranches during

which the Generating Unit is not dispatched or dispatched at less than 70% of the

load that has been instructed.

8.3 Clause 8.1 and clause 8.2 are not applicable to Merchant Generators not subject to

central dispatch.
