Why now?
17
US average electricity cost - $0.01 / kwh Electricity pricing
18
Commercial natural gas prices - $ / cu ft Natural gas pricing
19
Efficiency is the cheapest form of clean power
20
20:20:20 BEQ LEED Energy Star Net zero energy
21
Pilot phase 21 buildings 14.5M sq ft A- to C grades
23
LEED Millions of sq ft certified
25
Energy Star Millions of sq ft certified
26
How?
27
Intelligent buildings Day lighting Sub-metering Efficient lighting Occupancy sensing Variable speed drives Demand-based ventilation Continuous commissioning Utility automated demand/response Fully integrated building management system
28
Smart Grid & Demand / Response
29
What is the Smart Grid?
30
Use of digital information and controls to improve reliability, security and efficiency of the grid.
31
Use of smart automation systems that optimize the operation of buildings and homes.
32
Installation of smart meters to enable real time pricing
33
Deployment of demand / response
34
The Problem Energy Demand Coal Hydro Renewables Diesel Peaker Gas Turbine Spot Market $.04 $.06 $.10 $.25 $.30 $2.00 Energy Cost
35
Efficiency Original load Building power consumption - kw With energy efficiency 250 kW reduction
36
Demand / Response Original load Building power consumption - kw With energy efficiency With demand response
37
Auto Demand Response Demand Response - a utility requests energy curtailment during an anticipated peak period where demand exceeds supply. Utility options are: Purchase power on the spot market Start up old generation plants Build new power plants (very costly) Rolling blackouts Demand / Response Auto DR is an automated way to achieve demand reduction.
38
Demand response - lowest installed cost GENERATION ASSETINSTALLED COST ($ / kW) Photovoltaic$ 6,038 Solar thermal$ 5,021 Wind offshore$ 3,851 IGCC w/ CCS$ 3,496 Nuclear$ 3,300 IGCC$ 2,378 Scrubbed coal$ 2,058 Wind$ 1,923 Distributed gas – peak$ 1,645 Distributed generation – base$ 1,370 Gas plant$ 962 Demand response$ 573
