Problems with electric supply at Upper Stations
Power Outages! Several each year. Sometimes easily repairable, sometimes not. Causes: Broken insulators Underground cable splices Lightning arrestor failure Lightning Failing transformers
Safety issues Backup unreliable No backup for outbuildings Power surges Expense Pollution Consequences of electric supply problems at Barcroft Station

Discussion at Silver Peak substation
Metering equipment
Example of power monitoring data from 2004. This kind of detailed record is used for simulating power demand scenarios under different conditions.
Main electric loads Space heating!! Water heaters Room lights Refrigeration units Computers Scientific Equipment (need extra capacity for special uses)
In October 2004, we simulated winter heating demand by turning electric heaters on and off. For example, the simulation began at 8 am and ramped up to full capacity at around 9: 30.
Recommended Energy Supply Upgrades:
6000 gallons
Two 30 KW MTG units
Cover entire S-facing roof of quonset building – 10 -12 KW output
The APEP team has developed a quantitative dynamic simulation model which illustrates the costs and benefits of integrating distributed energy resources into the system.
The simulations show that the proposed system can readily convert to a permanent off-grid system. This is important as our grid connection is aging, and replacement would be prohibitively expensive.
