Editor's Notes
CO2 reduction calc.: solar offset grid @ 1100 lbs. per MW (CCNG power plant), 8.5MW*1100/2200=4.3 metric tons; CE5 elect. side 1100-1060=40 lbs. per MW*43.8=1752 lbs, plus heat at 500 lbs. per MW (80% efficiency heater)=51*500=25,000 lbs. + 1752 lbs.; = 12.4 metric tons Residential cost savings in PG&E territory $13,900 vs. $3500 = 4X NG offset by 8500 kWh is 830 therms, NG offset by CE5 is 2235 therms Commercial backup for costs: Solar @ 30% ITC, CSI @ $1.55 per watt = $23,650 CE5 @ 30% or $15,000 cap, SGIP @ $2.50 per watt = $27,500; residential Fed TC cap’d at $5000 Residential savings: CE5 from Atherton model, solar in PG&E @ Tier 5 rate of $.41/kWh Comc’l Savings: Solar all @ $.174 per kWh, CE5 all elect. @ $.174 per kWh, heat at $.91 per therm (save 140 therms/mo. =$1530) (produce elect. @ $.09 per kWh =$3360) Residential: Solar @ 30% ITC and CSI of $1.55 = $23,650 CE5 @ $5000 ITC and SGIP @ $2.50 = $17,500 Savings: Solar all @ $.41, CE5 from Atherton case study
