Introduction
´ 20+ years of electrical engineering in High-Tech
´ 5+ years in Solar and Renewable energy solutions
´ 1.5MW+ of solar installed across Canada (about 1.9GWh production per year)
´ Grid Tied and Hybrid Systems with Lithium-Ion batteries
Agenda
´ Introduction
´ Electricity Cost
´ Solar PV
´ CoGeneration
´ Smart Tech
´ Case Study
´ Electric Car
Audience?
´ What type of buildings do you manage ? Size…
´ Do you know how much you spend in utilities ? Hydro, NG, others ?
´ How many employees ? Rooms, parking spots?
´ Who knows what these are:
´ Solar PV System…
´ CoGeneration…
´ Smart-Tech…
…Today’s Cost?Time-of-use (TOU) Prices

CoGeneration
´ Meant for larger buildings
´ Uses NG
´ It can generate:
´ Electricity
´ Heat, steam
´ Chilled air or water
´ It can have ~92% efficiency

Case StudyResort in Caribbean
Night ~ 700KWpx 12h/day = 12.0 MWh/day
x 12h/Night = 8.4 MWh/Night
20.4 MWh/day or 20,400,000 Wh/day
+
Using the map for average solar hour radiation, USVI gives us average of 5.6 hours of full sun per day...
2 MW array x 5.6 h ~= 11.2 MW/h of power production
Calculations (estimated)
Day ~ 1MWhpConsumption:
Based on a 2MW number, then 2MW/300W panels ~= 6720 Panels

Preferred areas for Solar PV Installation
- Fuel Tank for ground mount
- 1 & 2 = Parking area for carport
- 3 = Left Parking area for ground mount
- TE = GEN Room, are to be used for roof mount
- CB = to be used for roof mount
- A-D = to be used for roof mount if necessary
- E-H = Will not be used
- MPC = Will not be used
Confidential
Preferred areas for Solar PV Installation
- Fuel Tank layout
- 3, Left Parking area layout
2865 x 310 W = 888,150 W

Electric Car
´ 133Km with 24KWh battery
´ A 66.5Km daily trip to work and back would need 12KWh+ of battery power
´ 8,000,000 cars in ONT, ½ are daily commuters to work = 4M cars
´ Lets further say 1/2 are carpooled = 2M cars traveling daily bases to work and back.
´ Every day 12kWh x 2,000,000 = 24,000,000kWh/day or 24GWh/day has to be produced to just cover car charging.
