ELECTRIC CITY CORPORATION

• Competitive Curtailment and Efficiency Remain One
  of the Most Cost Effective Long Term Solutions to
  Meeting Peak Demand
• Provide better balance against poor AC Driven
  Annual Load Factor/Utilization
• Better for a Utility when compared to a massive
  reduction in base consumption
• Can be provided at market driven rates
• Better than above market, demonstration projects
• Can Provide Utility with Real Control over Load
• Measurable, Controllable in Real Time

LIGHTING

• Why Lighting?
• A Primary Base Load
• Non-Seasonal - Always on when facility is in
  use.
• Steady Load Load varies very little from day to
  day.
• Easiest to Implement and Measure

11
Functional Control Arenas

• Stand-Alone
• System has its own network and control
• Operates totally independent of any other control
  or automation software
• Legacy Interface
• Universal I/O (digital or analog)
• Has additional inputs that will accept signals
  from other automation or control equipment
• 21 inputs and 20 outputs
• Has additional outputs to send status or alarm
  signals to other automation or control equipment

12
Functional Control Arenas

• Open Protocol
• BACnet (Building Automation Control Network)
• Supported by ASHRAE (American Society of Heating,
  Refrigeration Air-Conditioning Engineers)
• ANSI 135-2001
• Major building automation systems
• EnergySaver simply becomes an additional node or
  panel on any BACnet compatible system.

VNPP Benefits

• Methods of Control
• Emergency
• Scheduled in Advance
• Preset Variables
• Price/kW (Demand)
• Price/kWh (Usage)
• Demand Limit (do not exceed XXX kW)
• Ability to Curtail Large Aggregated Loads from
  Unrelated Facilities in Minutes
• Measurement Verification
• Historical Verification of Curtailment (last 50
  events)
• Current, Monthly or Annual History of Avoided
  Usage
• Assist in Avoiding Brown-Outs or Black-Outs
• Curtailment can be targeted down to substation or
  even feeder level
• Reduce Reserve Requirement
• Peak Load Generators Off Line
• Utility Excess Power Sale

Firm Load

• Utilities do not plan reserves for non-firm load.
• The EnergySaver can convert a portion of the
  Firm load into Non-Firm load.
