2. OSIsoft ( ) and Ice Energy (i e) i Youre Irrational!! Get Real!! e i + 1 = 0

3. 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

4. Ice Bear: Typical Rooftop Installation

5. kW Demand over 24-Hour Cooling Cycle Standard Cooling (8 kW) Fan Only during Ice Melt (1.7 kW) Ice Make Ice Melt Cooling (.3 kW)

6. 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

7. 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

8. 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

9. 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?

10. The Utilitys Perspective: SCADA

11. 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 utilitys 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

25. 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 dont impose ourselves on the architecture, rather, we are designed to fill in the gaps and dovetail with what exists.
