ice bear a distributed energy resource
Ice Bear: A Distributed Energy Resource
  • The “Ideal Battery”
    • Reduces ~6 kW of On-Peak demand
    • Shifts 32 kWh (95%) of A/C energy to off-peak
      • 5 MWH of Peak Shift Annually
    • Reduces Carbon & NOx Emissions by ~50%
    • Consumes the same amount of energy as a standard “DX” HVAC system
  • Provides cooling for 6 – 10 hours
    • Nominal settings are from 12 noon to 6 pm (6 hours)
    • Runs autonomously, or can be remotely dispatched
  • SmartGrid Ready
    • Aggregated to Multi-MW scale
    • 100% on-line

ice energy is more than just the ice bear
Ice Energy is more than just the Ice Bear
  • “The power grid is the largest machine ever made by mankind”
    • Millions of components working together, in true synchrony, yet fault tolerant
ice energy is more than just the ice bear1
Ice Energy is more than just the Ice Bear
  • Utilities have their ways of integrating and controlling this massive resource
    • Secure, complex, tightly integrated control environment
    • Historically, a “closed” architecture
  • New technologies and drivers are forcing change
    • Renewable Sources, Internet, Deregulation, Smart Devices, Open Architectures…
    • Industry response…the Smart Grid.
    • How we facilitate integration is critical to large scale deployment
ice energy is more than just the ice bear2
Ice Energy is more than just the Ice Bear
  • Integrating at the device level is difficult
    • Burdened with communication, safety, control, and security issues
      • Smart Meter, PCT, RAS, Local Generation examples
      • The Ice Bear has avoided these issues, as a device behind the meter
    • Influx of new players to address this problem
      • We can anticipate 20 years of development, new standards, changing industry structure
  • Integrating within SCADA is comparatively easy
    • Supervisory Control is common, and easily integrated
    • Data Historians are a ubiquitous tool for Data Access
utility requirements
Utility Requirements
  • “Can we control it?”
    • The prospect of controlling 20,000 separate Ice Bears is daunting
  • “Can we rely on it?”
    • Availability is critical. And can you really manage 20,000 units?
  • “Can you prove it?”
    • Information / Data Reporting
  • “Does it work with what I have?”
    • Regulated and “closed” architecture
  • “Will it work with SmartGrid?”
    • This is a moving target, with lots of players. How do we fit?
ice energy utility solution
Ice Energy Utility Solution
  • Integrate simply with utility SCADA Systems (Supervisory Control And Data Acquisition)
    • Supervisory Control
      • Phase 1: Utility defines standard Ice Bear Operation
      • Phase 2: Utility modifies control strategy monthly, weekly, daily, or hourly
        • Provide an interface as per each utility’s needs
    • Data Acquisition
      • Provide PI connectivity to the utility to serve results
      • Connects securely, seamlessly to our server
  • Utility middleware is bypassed
    • Reducing risk, constraints, complexity, and time

6) Utility creates special loading orders, as needed

  • Utility issues loading order:
  • For immediate or scheduled deployment
  • Shed or add load
  • Scoped by region, transmission, other…
  • Temporary or permanent changes

10) Utility reporting

7) DER Optimizer determines method, and acknowledges orders

  • DER Optimizer understands:
  • GIS and T&D locations
  • Maintenance / operational status
  • Customer imposed restrictions
  • Historical performance / expectation
  • Communication limitations
  • Additional DR assets

9) CoolData M&V

8) Units override default behavior as per request

large scale utility requirements
Large Scale Utility Requirements
  • “Can we control it?”
    • Phase 1: Utility provides nothing more than a standard operating schedule
    • Phase 2: We provide a Supervisory Control interface to the utility, designed to meet their specific needs
  • “Can we rely on it?”
    • OSIsoft is a proven reliable backbone, already vetted and accepted by the utility industry.
    • Ice Bear reliability has been proven in Utility-sponsored pilots and customer installations
  • “Can you prove it?”
    • You have all your data via a dedicated PI Server at your site.
  • “Does it work with what I have?”
    • Our solution integrates PI-to-PI, and does not require integration to SCADA middleware. In fact, we enable a faster, easier path for connectivity to additional DSM resources.
  • “Will it work with SmartGrid?”
    • Yes. We don’t impose ourselves on the architecture, rather, we are designed to fill in the gaps and dovetail with what exists.
