GC intake - 528.55 feet

GC intake - 528.55 feet. 10/28/08 photo (GC intake - 528.55.) shows the water level at Glacier Creek. The water level was 528.55 feet (spill elevation is 530.00) and the impound is drained down far enough so that CC is providing water to the hydro. CC intake - 509.98 feet.

  1. GC intake - 528.55 feet 10/28/08 photo (GC intake - 528.55.) shows the water level at Glacier Creek. The water level was 528.55 feet (spill elevation is 530.00) and the impound is drained down far enough so that CC is providing water to the hydro.

  2. CC intake - 509.98 feet 10/28/08 photo (CC intake - 509.98...) shows the water level at Clear Creek. The water level was 509.98 feet (spill elevation is 510.0) and the impound is just barely below the spill level. (100% of all available water is being used to generate electricity).

  3. CC intake - 510.06 feet 10/28/08 photo (CC intake - 510.06..) the hydro load was 600 kW and varying about +/-25kW. As the load increased the water level would drop below the spillway. As the load dropped the water would creep up and again start to spill. Finally around 11-ish, the load dropped a little and the water level increased and stabilized about 510.10. It was starting to rain at the time and the temperature at the intakes was 39F.

  4. CC Weir - spill ht approx 0.4 feet 10/29/08 photo (CC Weir - spill ht approx 0.4 feet) This morning at 9:40 am the hydro was carrying the load at about 630 kW, GC was not spilling and the water level at CC was about 0.4-feet. This photo is pretty grainy due to heavy rain. So, it appears the available water today is much greater than yesterday.

  5. KCED Delta Creek Hydro - cfs vs Kw This spreadsheet estimates available kW from spilled water level - based on original design data. The chart indicates that for a 0.4-foot spill height, there is about 339 kW of spilled energy (this equates to roughly 8.5 gallons / hour of equivalent electric heat.)

  6. KCED SCADA – status page 10/29/08 - This slide shows the Status page of the KCED Hydro and Diesel generating system. Currently the Hydro is offline while the intake reservoirs (impound and forebay) are being cleaned out.

  7. GEN1 SCADA page – CAT 3512C 10/29/08 - This is the GEN1 SCADA page that shows the status of the new 3512C. Current load is 628 kW and instantaneous fuel efficiency is 15.16 kWh/gallon (this is a remarkably good fuel efficiency for a 1050 kW genset operating at 60% of full load)

  8. Heat Recovery SCADA page 10/29/08 - This slide shows the Heat Recovery System page. With the 3512C on line at 628 kW the heat provided to the KC School is equivalent to about 4-gallons / hour.
