<br />8,800 cfs (343 MW) during offpeak hours ramping up to a maximum <br />of 14,800 cfs (578 MW) during onpeak hours for a majority of the <br />month. This followed the maximum daily fluctuation limit of <br />6,000 cfs per day (235 MW). Weekend releases were adjusted <br />downward to follow reduced weekend loads. <br /> <br />~ <br /> <br />~ <br /> <br />Releases from Flaming Gorge and the Aspinall Unit were relatively <br />high for the first week of the month. The Yampa River was <br />supplying all water requirements for the endangered fish studies. <br />The economy energy market tightened in the last week of June due <br />to several unplanned unit outages. <br /> <br />4. Power SchedulinQ and Purchases for Julv 1994 <br /> <br />Water releases from Glen Canyon powerplant totaled 846,000 AF for <br />the month of July. The weekday generation pattern was pre- <br />scheduled at approximately 10,800 cfs (427 MW) during off-peak <br />hours ramping up to approximately 18,800 cfs (743 MW) during on- <br />peak hours. Daily generation fluctuations were limited to ' <br />8,000 cfs (316 MW).

Flaming Gorge generation was <br />increased to support endangered fish flows on the Green River at <br />Jensen, providing generation flexibility. Due to reasonable <br />energy prices and abundant energy on the economy energy market, <br />Montrose was able to back down Glen Canyon water releases <br />approximately 25,000 AF for later use in August and September. <br /> <br />5, Power SchedulinQ and Purchases for AUQust 1994 <br /> <br />Water releases from Glen Canyon powerplant totaled 860,000 AF for <br />the month of August. For most of the month, weekday generation <br />patterns were pre-scheduled at approximately 9,500 cfs (373 MW) <br />during off-peak hours ramping up to approximately 17,500 cfs <br />(688 MW) during on-peak hours. The daily generation fluctuation <br />rate was limited to 8,000 cfs (315 MW) for the month. Weekend <br />releases were adjusted downward to follow reductions in weekend <br />loads. <br /> <br />< <br /> <br />.:i <br /> <br />. , <br />~ <br /> <br />> <br /> <br />" <br /> <br />'-.' <br /> <br />:. <br />~~ <br />I~ <br />,. <br />~~ <br /> <br />. ~ , <br /> <br />~ <br /> <br />In mid-August the temperatures were hot and the economy energy <br />market tightened with very high prices (36-40 mills/kWh). <br />Montrose began releasing water from Glen Canyon, which had been <br />saved in July to avoid paying the high prices. On August 18 the <br />cheapest energy available was 46 mills/kWh. Montrose contacted <br />the Bureau to confirm system reQulatinQ capability at Glen Canyon <br />and advise the Bureau that Glen Canyon would be run at the <br />maximum 20.000 cfs release rate as defined in the exception <br />criteria due to the unavailability and expense of enerQV on the <br />system. Montrose interchanged available energy from the Loveland <br />Area Office (LAO) and resulted in releases from Glen Canyon at <br />19,000 cfs maximum. In the last weeks of August energy remained <br />tight and energy prices remained higher-than-normal until the <br />long-term energy contractors returned to the market. <br /> <br />~ <br />~ <br />.. <br />o. <br />'. <br />~ <br /> <br />3 <br />
