Per­form, Achieve & Trade

Intro­duc­tion
The National Action Plan on Cli­mate Change was released by Hon­or­able Prime Min­is­ter of India in June 2008
The Action Plan Out­lines 8 Mis­sions ; Each Mis­sion has out­lined spe­cific goals

Mis­sions under NAPCC
National Solar Mission
National Mis­sion for Enhanced Energy Effi­ciency (NMEEE)
National Mis­sion on Sus­tain­able Habitat
National Water Mission
National Mis­sion for Sus­tain­ing the Himalayan Ecosystem
National Mis­sion for a Green India
National Mis­sion for Sus­tain­able Agriculture
National Mis­sion for Strate­gic Knowl­edge for Cli­mate Change

NMEEE Mis­sion Goals
Market-​based approaches to unlock energy effi­ciency oppor­tu­ni­ties, esti­mated to be about Rs. 74,000 Crores By 201415:
Annual fuel sav­ings– with a Tar­get of 10 mil­lion toe from Energy Inten­sive Indus­tries (Des­ig­nated Consumer)spread over 8 Sectors;
Cumu­la­tive avoided elec­tric­ity capac­ity addi­tion of 19,000 MW
CO2 emis­sion mit­i­ga­tion of 98 mil­lion tons per year

One of the New Ini­tia­tives under NMEEE (Rel­e­vant to Ther­mal Power Stations):

PER­FORM, ACHIEVE & TRADE:

The mar­ket based mech­a­nism to enhance the cost effec­tive­ness in improv­ing the Energy Effi­ciency in Energy Inten­sive indus­tries through cer­ti­fi­ca­tion of energy sav­ing which can be traded

The PAT Scheme Under Energy Con­ser­va­tion Rules, 2012

(PAT RULES)

BASIC FRAME­WORK OF PAT SCHEME

• Mech­a­nism –

Tar­get Set­ting & Com­pli­ance Period by Admin­is­tra­tor (CEA & BEE)
Mon­i­tor, Ver­i­fi­ca­tion & Cer­ti­fi­ca­tion by Des­ig­nated Energy Audi­tors (DENA) (Accred­ited by BEE)
Under­achiev­ers – Penal­ized by buy­ing ESCerts (Energy Sav­ings Cer­tifi­cate), Over­achiev­ers – Issuance of ESCerts for bank­ing or trad­ing for later use.

Activ­ity Flow –

Infor­ma­tion through Base­line Audit (Aver­age of Three Years data)
Tar­get Set­ting (Dec­la­ra­tion of Base Year, Tar­get Year)
Com­mu­ni­ca­tion to Des­ig­nated Con­sumer ( All Power Sta­tions of WBPDCL).
Prepa­ra­tion of Per­for­mance Assess­ment Doc­u­ment (PAD or Form A) & Com­mu­ni­ca­tion to BEE/​SDA (State Des­ig­nated Agency)
Ver­i­fi­ca­tion of PAD through DENA (Form B)
Ver­i­fi­ca­tion check by DENA and sub­mis­sion of com­pli­ance doc­u­ment (FORM D)

Spe­cific Energy Con­sump­tion (SEC)

SEC = E /​P

Where E = Input Energy Amount (eg Coal in kg for Ther­mal Power Plants),
P = Out­put Prod­uct (Elec­tric­ity in Kwh for Ther­mal Power Plants)

Esti­ma­tion of Energy sav­ing (MTOE= Met­ric Ton of Oil Equivalent)

= Pbase X (SECbase - SECtar­get)

Pbase = Base­line Pro­duc­tion: Aver­age of 20078, 20089 & 2009-​10
SECbase = Aver­age of 20078, 20089 & 2009-​10
SECtar­get = SEC as esti­mated in 201415

1 MTOE = 1 ESCert
1st Cycle from 201213 to 201415 (3 years cycle)
Total Com­pli­ance Period is March 2015
After three years a com­plete mea­sure­ment will be under­taken for ver­i­fy­ing SEC and plant capac­ity for each Des­ig­nated Con­sumers by DENA.

Correction/​Normalization Fac­tors – Fac­tors which affect SEC

Input Pri­mary Energy (Fuel Link­age & Qual­ity of Fuel) (As fired Basis Coal)
Capac­ity Uti­liza­tion (Back­down, Non-​availability of Fuel)
Envi­ron­men­tal Stan­dards & Nat­ural Disaster

For every devi­a­tion from tar­get authen­tic doc­u­men­ta­tion should be pre­sented to BEE/​Energy Audi­tors for incor­po­ra­tion of correction/​normalization factors.

Esti­mated National Tar­get (Energy Sav­ings) = 6.6MTOE at the end of 1st PAT Cycle (201415).

Stake­hold­ers
Admin­is­tra­tor : MoP/​Central Govt (CERC in the case of Ther­mal Power Stn.)
Nodal Agency : Bureau of Energy Efficiency
Imple­menter : Des­ig­nated Con­sumers like KTPS, BTPS, BkTPP, SgTPP and STPS
State Admin­is­tra­tor : State Des­ig­nated Agency like WBSETCL
Ver­i­fier : Accred­ited Energy Audi­tor ( to be Des­ig­nated by MoP)

Role of Cen­tral Govt.

As per noti­fi­ca­tion dated the 30th. March, 2012, issued by Min­istry of Power, Govt. of India, New Delhi on ‘Per­form Achieve and Trade (PAT)’,issued under EC Act 2001, Tar­get Spe­cific Energy Con­sump­tion i.e. Net Heat Rate (Kcal/​Kwhr) of five Ther­mal Power Sta­tions of WBPDCL have been noti­fied which have to be achieved by 201415.

MIN­ISTRY of POWER, New Delhi, Vide NOTI­FI­CA­TION Dated the 30 th March, 2012. [pub­lished in Part-​II Section-​3, Sub-​Section (ii) of Gazette of India, Extra­or­di­nary], in con­sul­ta­tion with the Bureau of Energy Effi­ciency, spec­i­fied for the des­ig­nated con­sumers the energy con­sump­tion norms and stan­dards for the period from 201213 to 201415 in rela­tion to their cur­rent level of energy con­sump­tion, being the base­line energy con­sump­tion norms and stan­dards which need to be com­plied within the tar­get year 201415.

Note:
A. New Units like Bakresh­war U# 4 & 5 and San­taldih U # 6 are not con­sid­ered for PAT.
B. In case of STPS, capac­ity con­sid­ered is 490 MW ( 4 x120 + 1 x 250), which is an error; same taken up with CEA.

WBPDCL have ini­ti­ated a num­ber of Effi­ciency Improve­ment Mea­sures, adopted Bet­ter O & M Prac­tices and taken up R & M Jobs which shall improve Plant Per­for­mances and enable to achieve the Noti­fied Target.
