BARCROFT DEMAND DATA

POWER MONITORING SUMMARY

• AVERAGE DEMAND SUMMARY (kW)

• Pace and large animal buildings consume more
  than 52 of the average power (and energy)
• Observatory consumes approximately 29 of the
  power and energy at Barcroft
• Remaining 19 goes to small animal and telescope
  buildings.

PV IMPACTS (SIMULATED)

PV IMPACTS (SIMULATED)

• Using demand data from September, simulations
  were performed analyzing the economic impacts of
  varying the installed PV capacity 5,10,15, and
  20kW

• Peak reduction benefit disappears for this month
  after 10kW of PV (peak occurring with no solar
  power available is maintained)
• - cost of peak demand is 5.40/kW during winter
  (savings 36/month), and 13.15/kW during summer
  (June September savings 87/month)

FUTURE WORK

• Complete analyses of generation technologies
• Investigate interconnection issues
• Install infrastructure for future heating and
  generation installations
• Get funding to make it happen!
