1 Generatr NYISO Expectatins f Generatr Operatin During a Gas CurtailmentRestrictin r Operatinal Flw Order (OFO)Interruptin User s Guide Intrductin: On days when gas system reliability culd be at risk, the Lcal Distributin Cmpany (( LDC), ), interstate r intrastate gas pipeline may, as permitted by its Federal Energy Regulatry Cmmissin ( FERC ) r New Yrk Public Service Cmmissin ( NYPSC ) apprved tariffs r custmer cntract, invke an Operatinal Flw Order (( OFO) ) r issue ther instructins restricting use f gas imbalance service. Under extreme circumstances, interruptible custmers may als have their gas service interrupted t prtect gas system reliability. Unlimited use f balancing gas by generatrsgeneratrs culd, in sme circumstances, endanger gas system reliability. This dcument is applicable t all generatrsgeneratrs that are available t be Bid int the NYISO markets, but fr r subject t ptential fuel limitatins. When the Generatr s LDC r pipeline has issued an OFO, r instructinsther legally authrized instructin restricting imbalance usage, the use f gas balancing services, a Generatr may be subject t unauthrized use charges r t penalties fr incurring gas imbalances that exceed certain limited tlerances specified in the OFO r instructin. As a general practice, the NYISO will nt rdinarily permit inclusin in generatrgeneratr reference levels f unauthrized use charges r penalties fr vilating Operatinal Flw Orders r fr vilating legally authrized LDC/pipeline instructins restricting gas usage. Hwever, if and t the extent that a Market Party has btained specific authrizatin frm the relevant natural gas LDC r pipeline t use gas at a Generatr that wuld therwise be unauthrized r subject t a penalty, the ISONYISO shall nt cnsider such usage t be unauthrized use. Market Parties shall make every effrt t clearly dcument authrizatin they btain frm an LDC r pipeline. Dcumentatin btained after the fact will be cnsidered. This dcument describes the NYISO s expectatins fr entities that Bid int the NYISO administered markets during times when an Operatinal Flw Order (OFO) r ther legally authrized instructins restricting imbalance usagethe use f balancing services are in effect. This guide is written in general terms that may nt apply t a Generatr s unique circumstances. Installed Capacity Prviders have an bligatin t Bid, schedule, r ntify fr all hurs in the Day-Ahead Market ( DAM ) in accrdance with Market Administratin and Cntrl Area Services Tariff ( Services Tariff ) Sectin In additin t the Services Tariff requirements fr Installed Capacity Prviders, it is generally expected that any available generatrgeneratr that is acting in a cmpetitive manner wuld be bidding int bth the Day-Ahead Market and the Real-Time Market.

2 Fr purpses f this dcument, the term OFO refers t a legally authrized Operatinal Flw Order issued by the LDC r pipeline t which a Generatr is intercnnected. Fr purpses f this dcument, the term interruptin refers t a legally authrized ntice f interruptin r temprary service discntinuance issued by the LDC r pipeline t which the Generatr is intercnnected. The failure f a gas-nly Generatr t ffer additinal incremental Energy r Ancillary Services (in excess f its scheduled MWs) energy r ancillary services in real-time during an OFO due t the inability f the Generatr t btain r deliver gas, t the Generatr s pipeline meter r LDC meter as a result f the OFO wuld be deemed cnduct cnsistent with cmpetitive behavir fr purpses f physical withhlding evaluatins cnducted pursuant t the NYISO s Market Pwer Mitigatin Measures (Services Tariff Sectin 23). If an interruptin f gas service ccurs befre Day-Ahead Market Bid windw clses, gasgas-nly generatrsgeneratrs are nt expected t Bid int the Day-Ahead Market t the extent they are unable t btain fuel. Such generatrsr deliver gas t the Generatr s burner tip. If an interruptin f gas transprtatin service is annunced by a gas transprtatin service prvider befre the Day-Ahead Market Bid windw clses, a Generatr wuld be expected t ntify NYISO utage scheduling f a frced utage (t the extent it is unable t btain r deliver gas t the Generatr s pipeline meter r LDC meter. See Sectin 4.0 GADS Reprting Sectin).. If an interruptin f gas service ccurs after a gas-nly generatrgeneratr receives a Day-Ahead Market schedule, the generatrgeneratr is expected t deratebe derated fr lack f fuel (Seesee Sectin 4.0 GADS Reprting Sectin), and is expected t ntify the NYISO f its unavailability due t lack f fuel thrugh its Transmissin Owner ( TO. ). 1. Daily Operatinal Flw Order (OFO) During a daily OFO, the fllwing rules apply: 1.1 Gas Only Generatrs Single Generatr Day-Ahead Market Expectatins Since ne electric day spans prtins f tw gas days, Generatrs Bids shuld cnsider the OFO fr the apprpriate 24-hur gas day. A Generatr is expected t reflect any csts (risks) assciated with perating during an OFO perid in its Bidsand fr cmplying with the OFO restrictins in its Bids. Cnsistent with Services Tariff Sectin , charges assciated with vilating an OFO may nt be included in Generatr reference levels Real-Time Market Expectatins A gas-nly Generatr is nt expected t ffer additinal, incremental Energy r Ancillary Services in real-time during an OFO if it cannt prcurebtain r deliver additinal gas t the Draft fr Discussin Purpses Only Page 2

A gas-nly Generatr is expected t ffer int the Real-Time Market during whenever it is capable f btaining r delivering gas t the available gas nminatin peridsgeneratr s pipeline meter r LDC meter and perating in real-time, even if the Generatr was nt awarded a Day-Ahead Market schedule. A gas-nly Generatr is expected t ffer int the Real-Time Market during the available gas nminatin perids if the Generatr was awarded a Day-Ahead Ancillary Services schedule fr hurs utside the available gas nminatin perid. If a Generatr is unable t r chses nt t ffer in the Real-Time Market during the perid it was awarded a Day-Ahead Ancillary Services schedule, the Generatr must be derated t 0 MW fr that time perid. (See thesectin 4.0 GADS Reprting sectin in this Users Guide fr details n reprting derates in GADS).. The failure f a gas-nly Generatr t ffer additinal incremental Energy r Ancillary Services (in excess f its Day-Ahead scheduled MWs) in real-time, during an OFO, due t the inability t btain gasr deliver additinal gas t the Generatr s pipeline meter r LDC meter wuld nt be cnsidered physical withhlding pursuant t the NYISO s Market Pwer Mitigatin Measures (Services Tariff Sectin 23). 1.2 Dual Fuel Generatrs Single Generatr Day-Ahead Market Expectatins A dual-fuel Generatr that has been assigned a default reference fuel type f gas, but is unable t btain gasr deliver gas t the Generatr s pipeline meter r LDC meter due t an OFO, might nnetheless be able t run n il fr the day. In such circumstances, the Generatr is expected t include a fuel type adjustment (frm gas t il) in its Market Infrmatin System (( MIS) bid ) Bid frm Real-Time Market Expectatins Generatrs that wuldare therwise be available, but fr the inability t btain gas due t an OFO, are expected t Bid fr all hurs f the Real-Time Market.

See the Sectin 4.0 GADS Reprting sectin fr details n hw t reprt this derate in GADS) Prtfli (cmbinatin f gas nly & dual fuel generatrsgeneratrs) Day-Ahead Market Expectatins A Generatr is expected t reflect any csts (risks) assciated with perating during an OFO perid in its Day-Ahead Market Bidsand fr cmplying with the OFO restrictins in its Bids. Cnsistent with Services Tariff Sectin , charges assciated with vilating an OFO may nt be included in Generatr reference levels. Alternatively, t the extent a dual-fuel Generatr reasnably expects it will be unable t btain gasr deliver additinal gas t the Generatr s pipeline meter r LDC meter it culd Bid n its alternate fuel during an OFO perid Real-Time Market Expectatins Generatrs that wuldare therwise be available, but fr the inability t btain gas due t an OFO, are expected t Bid MWs in the Real-Time Market that were nt scheduled in the Day- Ahead Market. Generatrs are expected t Bid additinal available capacity int the Real- Time Market when the prtfli can perate within the balancing service allwed during the OFO. Generatrs that have sufficient il are expected t Bid int the Real-Time Market. If, due t an OFO, a Generatr cannt securebtain r deliver sufficient gas t its pipeline meter r LDC meter t meet the Generatr s Day-Ahead Market schedule, and n alternative fuel is available, the NYISO expects the Generatr t take a frced utage (. See Sectin 4.0 GADS Reprting Sectin).. If a Generatr with sufficient il chses nt t Bid int the Real-Time Market, the Generatr must derate t 0 mw (MW. See the Sectin 4.0 GADS Reprting sectin fr details n hw t reprt this derate in GADS).. Generatrs are expected t Bid additinal available capacity inint the Real-Time Market utside the available gas nminatin perids when the prtfli can perate within the balancing service allwed during the OFO. 1.4 Prtfli (Gas-nly generatrs)generatrs) Day-Ahead Market Expectatins A Generatr is expected t reflect any csts (risks) assciated with perating during an OFO perid in its Day-Ahead Market Bidsand fr cmplying with the OFO restrictins in its Bids. Draft fr Discussin Purpses Only Page 4

5 Cnsistent with Services Tariff Sectin , charges assciated with vilating an OFO may nt be included in Generatr reference levels. If, due t an OFO, a gas-nly Generatr des nt expect t be able t securebtain r deliver sufficient gas t its pipeline meter r LDC meter t supprt bidding int the Day-Ahead Market, the NYISO expects the Generatr t take a frced utage (See Sectin 4.0 GADS Reprting Sectin) and is expected t ntify utage scheduling Real-Time Market Expectatins Generatrs that are able t nminatebtain r deliver gas t the Generatr s pipeline meter r LDC meter are expected t bidbid in the Real-Time Market during the available gas nminatin perids. Generatrs are expected t Bid additinal available capacity in the Real-Time Market utside the available gas nminatin perids when the prtfli can perate within the balancing service allwed during the OFO. If, due t an OFO, a gas-nly Generatr cannt securebtain r deliver sufficient gas t its pipeline meter r LDC meter t meet the Generatr s Day-Ahead schedule, the NYISO expects the Generatr t take a frced utage (See Sectin 4.0 GADS Reprting Sectin) and is expected t ntify the NYISO f its unavailability due t lack f fuel thrugh its TO. Example #1: The NYISO wuld expect a gas-nly prtfli t stack the generatrsgeneratrs by heat rate (cst). If a prtfli knws that they culd have five f their generatrsgeneratrs receive Real-Time Market schedules, and they culd withut vilating an OFO instructin requiring Generatrs t stay within the 2% prtfli restrictinf their daily schedule, then they shuld ffer thse five generatrsgeneratrs in the RTReal-Time Market. It wuld be cnsidered cnsistent with cmpetitive behavir t nt Bid the remaining generatrsgeneratrs in the prtfli int the RTReal-Time Market. Example #2: When bidding int the RTReal-Time Market, a gas-nly prtfli must take int cnsideratin that the current bidding hur impacts the secndfuture bidding hurhurs. If a gas-nly prtfli assumes full cmmitment fr the secndnext bidding hur, and wuld still have bandwidth fr thet abide by an OFO instructin t remain within 2% prtfli restrictinf their daily schedule with full cmmitment, then the prtfli shuld cntinue t Bid fr the fllwing hur. If the prtfli assumes full cmmitment fr the secnd bidding hur and wuld have n bandwidth frwithin the 2% prtfli restrictin, then they wuld nt be cnsidered physical withhlding pursuant t the NYISO s Market Pwer Mitigatin Measures (Services Tariff Sectin 23) if they didn tdid nt Bid all f their generatrsgeneratrs fr the fllwing hur. Example #3: Draft fr Discussin Purpses Only Page 5

6 If the prtfli is n track t under burn fr the day in cmparisn t theirits gas nminatin ( (i.e., lng n gas ), the expectatin wuld be that the generatrgeneratr asset wner wuld ffer int the Real-Time Market MWs nt scheduled in the Day-Ahead Market. Hwever, if prducing an additinal MW puts the prtfli int a situatin whichthat vilates the OFO, then the NYISO wuld nt find the generatrsgeneratrs t be physically withhlding if they didn t ffer int the Real-Time Market. If prducing an additinal MW des nt put the prtfli int a situatin whichthat vilates the OFO, then the NYISO wuld expect the prtfli t ffer. If the prtfli is nt ffered in this situatin, then the generatrsgeneratrs nt ffered wuld be evaluated fr Physical Withhldingphysical withhlding cnduct and impact. Example #4: Pst Cycle Transactins. IfIn cases where a generatrgeneratr is intercnnected with an LDC r pipeline that ffers nminatin cycles after the cnclusin f the gas day ( pst cycle ), and if a Generatr can typically btain pst-cycle gas, then the NYISO wuld expect that generatrgeneratr t ffer int the RTReal-Time Market based n the prbability f getting pst-cycle gas. 2 Hurly (Ratable) Operatinal Flw Order (OFO) 2.1 Gas Only Generatrs Single Generatr Day-Ahead Market Expectatins During an hurly r 1/24th OFO, a gas LDC r pipeline may require its Generatr custmers t maintain similar levels f gas usage acrss an entire gas day. Fr gas-fired GTs that might nly receive DAM schedules fr an hur r tw f the gas day, the DAM schedule might, in sme cases, frce a Generatr t buy mre gas than it actually needs, and then sell the extra gas it purchased at a lss.cnsistent with the relevant balancing prgram. The NYISO will wrk with generatrsgeneratrs that face such a risk t include temprary adders in Day-Ahead Market start-up reference levels t allw Generatrs t reflect expected sell-back lsses. If, due t an OFO, a Generatr cannt securebtain r deliver sufficient gas t its pipeline meter r LDC meter t supprt its Bid int the Day-Ahead Market, and n alternative fuel is available, the NYISO expects the Generatr t take a frced utage (. See Sectin 4.0 GADS Reprting Sectin).. Generatrs that are Installed Capacity Suppliers are expected t Bid in accrdance with Services Tariff Sectin fr all hurs f the Day-Ahead Market. If the OFO is called prir t the Day-Ahead Market Bid windw clsing, the NYISO expects that the Generatr wuld include the csts assciated with perating during a ratable OFO, and within the OFO restrictins, in its Day-Ahead Market Bid.

7 2.1.2 Real-Time Market Expectatins A gas-nly Generatr is nt expected t ffer additinal, incremental energyenergy r ancillary servicesancillary Services abve theirits DAM award in real-time during an OFO if it cannt prcurebtain r deliver additinal gas t its pipeline meter r LDC meter r wuld have t use unauthrized gas services in rder t perate t effectuate its energyenergy r ancillary serviceancillary Service ffer. If a generatrgeneratr Bids int the RTReal-Time Market and that Bid results in vilating the OFO, the penalty charges will nt be included in reference levels r in the calculatin f the generatr sgeneratr s cmpensatin. Generatrs are expected t cmply with the prvisins f OATT Sectin 34 (als referred t as OATT Attachment BB). If the generatrgeneratr is determined t be a Lcal Critical Generatr r a Bulk Critical Generatr and said Critical Generatr has crdinated Feasible Natural Gas delivery with the LDC as utlined in OATT Attachment BB, it is expected that the generatrgeneratr will bidbid fr all applicable hurs in the RTReal-Time Market. As utlined in Services Tariff Sectin , if and t the extent a Market Party has btained specific authrizatin frm the relevant natural gas LDC r pipeline t use gas that wuld therwise be unauthrized, such use shall nt be cnsidered unauthrized use by the ISONYISO and the Market Party wuld be expected t bidbid fr all hurs in the RTReal- Time Market. Market Parties shall make every effrt t clearly dcument authrizatin they btain frm the LDC r pipeline. Dcumentatin btained after the fact will be cnsidered. If a generatr has n accepted Generatr des nt have a DAM schedule, and has nt prcured gasbeen able t btain r deliver gas t its pipeline meter r LDC meter fr the RTReal-Time Market, the generatrgeneratr has tw ptins: The generatrgeneratr can bidbid int the RTReal-Time Market. The bidbid shuld include the csts t prcurebtain r deliver sufficient gas t the Generatr s pipeline meter r LDC meter t satisfy the restrictins f the OFO. If a generatrgeneratr cannt prcurebtain r deliver sufficient gas t the Generatr s pipeline meter r LDC meter, then the generatrgeneratr wuld nt be expected t bidbid int the RTReal-Time Market. The NYISO wuld expect the Generatr t enter a Reserve Shutdwn cnditin (. See Sectin 4.0 GADS Reprting Sectin).. There wuld be n evaluatin fr physical withhlding pursuant t the NYISO s Market Pwer Mitigatin Measures (Services Tariff Sectin 23) in this circumstance. If a generatrgeneratr has a DAM Ancillary Service schedule, but has nt prcuredbtained r delivered gas t its pipeline meter r LDC meter fr any hurs ther than that ancillaryancillary Service schedule, the generatrgeneratr has tw ptins: Draft fr Discussin Purpses Only Page 7

8 The generatrgeneratr can bidbid int the RTReal-Time Market fr all hurs, including thse utside the Ancillary Service schedule. The bidbid shuld include the csts t prcurebtain r deliver additinal gas t the Generatr s pipeline meter r LDC meter t satisfy the restrictins f the OFO. If a generatrgeneratr cannt prcurebtain r deliver additinal gas t its pipeline meter r LDC meter, then the generatrgeneratr wuld nt be expected t bidbid int the RTReal-Time Market utside the hurs f the Ancillary Service schedule. The NYISO wuld expect the generatrgeneratr t enter a Reserve Shutdwn cnditin fr the hurs utside the Ancillary Service schedule (. See Sectin 4.0 GADS Reprting Sectin).. If a generatrgeneratr has a DAM Ancillary Schedule Service schedule but cannt prcurebtain r deliver gas t its pipeline meter r LDC meter t satisfy this schedule in the RTReal-Time Market, then the NYISO wuld expect the generatrgeneratr t take a frced utage (. See Sectin 4.0 GADS Reprting Sectin).. The failure f a gas-nly Generatr t ffer additinal incremental Energy r Ancillary Services (in excess f its scheduled MWs) energy r ancillary services in real-time during an OFO due t the inability t btain gasr deliver gas t its pipeline meter r LDC meter, wuld be deemed cnduct cnsistent with cmpetitive behavir fr purpses f physical withhlding evaluatins cnducted pursuant t the NYISO s Market Pwer Mitigatin Measures (Services Tariff Sectin 23). During an hurly r 1/24th OFO, a gas LDC r pipeline may require its Generatr custmers t maintain similar levels f gas usage acrss an entire gas day. Fr gas-fired GTs that might nly receive DAM schedules fr an hur r tw f the gas day, the DAM schedule might, in sme cases, frce a Generatr t buy mre gas than it actually needs, and then sell the extra gas it purchased att the LDC r pipeline pursuant t a lss.balancing service. The NYISO will wrk with generatrsgeneratrs that face such a risk t include temprary adders in DAM start-up reference levels t allw Generatrs t reflect expected sell-back lsses. 2.2 Oil Generatrs Single Generatr Day-Ahead Market Expectatins During an hurly (ratable) OFO, an il-fired generatrgeneratr that has nt already been scheduled t prvide nn-synchrnus reserves, r t start, and that must start n natural gas might need t find intraday startup gas. This may invlve the generatrgeneratr btaining authrizatin frm the LDC r pipeline allwing use f the startup gas. If the ability t btain authrizatin is unknwn at the time the generatrgeneratr is bidding int the DA MarketDAM, then the NYISO wuld expect the generatrgeneratr t include in their bid the risk (cst) f nt being granted the authrizatin in its Bid.

9 2.2.2 Real-Time Market Expectatins If the LDC r pipeline refuses t authrize the use f start-up gas, then an il-fired generatrgeneratr that must start n natural gas is nt expected t bidbid in the Real-Time Market while the OFO is in effect. (See Sectin 4.0 GADS Reprting Sectin) Dual Fuel Generatrs Single Generatr Day-Ahead Market Expectatins Generatrs that are Installed Capacity Suppliers are expected t Bid in accrdance with Services Tariff Sectin fr all hurs f the Day-Ahead Market. A dual-fuel Generatr that has been assigned a default reference fuel type f gas, but is unable t btain gasr deliver additinal gas t its pipeline meter r LDC meter due t an OFO, might nnetheless be able t run n il fr the day. In such circumstances, it is expected the generatrgeneratr will include a fuel type adjustment (frm gas t il) in its Market Infrmatin System (MIS) bid Bid frm Real-Time Market Expectatins Generatrs that wuldare therwise be available, but fr the inability t btain gas due t an OFO, are expected t Bid fr all hurs in the Real-Time Market. A dual-fuel Generatr that has been assigned a default reference fuel type f gas, but is unable t btain gasr deliver additinal gas t its pipeline meter r LDC meter due t an OFO, might nnetheless be able t run n il fr the day. By including a fuel type adjustment (frm gas t il) in its Market Infrmatin System (MIS) bidmis Bid frm, the Generatr may avid unnecessary mitigatin. 3 Interruptin f Gas Service 3.1 Gas Only Generatrs Day-Ahead Market Expectatins If interruptin f gas service ccurs r a ntice f interruptin has been issued by the pipeline r LDC befre Day-Ahead Market Bid windw clses, generatr are nt expected t Bid int the Day-Ahead Market.

GeneratrGeneratrs must reprt status apprpriately in GADS (. See Sectin 4.0 GADS Reprting Sectin).. Installed Capacity Suppliers lcated East f Central-East shall Bid in the Day-Ahead Market all Capacity available fr supplying 10-Minute Nn-Synchrnized Reserve (unless the Generatr is unable t meet its cmmitment because f an utage as defined in the ISONYISO Prcedures).

If the TO determines that the generatrgeneratr is required fr reliability, the TO will place the generatrgeneratr OOM (which will allw the generatrgeneratr t autmatically recver any additinal csts incurred withdue t switching t its alternate fuel) and the generatrgeneratr wuld be expected t switch t its alternate fuel. If the TO des nt require the generatrgeneratr t switch t its alternate fuel fr reliability, the generatrgeneratr will then decide t either switch t its alternate fuel and run withut any mechanism t recver additinal csts assciated with switching t its alternate fuel; r it will chse t shut dwn, derate t 0 MW and reprt the utage apprpriately in GADS (.
