Vogler / CEO of TexasMicroGRIDS DISTRIBUTED GENERATION DISTRIBUTED GENERATION & ENERGY EFFICIENCY Rooftop SOLAR PV Renewable Generation, increased property market value, lower electric cost Site specific, measured in $/kW Insulation, White Polymer Roof Cap LOWER HVAC Operating Cost BTUs & $/kW Energy Savings Load Shaving, LED Lighting Energy Cost, $/kW WATER Conservation Less Gallons per month $/1000 Gallons Largest Solar PV Rooftop System in Texas Added Market Value > $2M SOLAR + ENERGY STORAGE SOLUTION Solar PV + Energy Storage = MicroGRID Backup Power / Higher Power Quality / Islanding BESS-2500 ENERGY STORAGE SOLUTION UtiliCELL BESS-2500 “Micro-GRID on a Skid” 250 kW Power / 500kWh Energy Positive impact on a customer's balance sheet Continuous Conversion Dual Utility Feeds Solar PV Input Asynchronous Wind Input Primary & Secondary Diesel Generator Auto Start Control VAR & Frequency Ancillary Services Can be Pushed Upstream Mobile Wheeled Option ENERGY STROAGE COMMON APPLICATIONS Unterrupitble Power Supply (UPS) Emergency power when mains power fails. Usually short duration discharge- to power up stand-by power source, properly shutting protected equipment. Main uses data centers, heavy industrial applications such as electrical equipment or refrigeration, critical health facilities and emergency response/management. ENERGY STORAGE COMMON APPLICATIONS Demand Charge & Peak Shaving Goal is to offset peaks in highly variable loads, thus avoiding higher demand charges from the utility. The demand charge is based on the highest capacity required during a given billing period for a 15-minute interval. Demand charge can be up to 40 percent of the electric bill and is often the easiest to control and economize with a battery system. Load Shedding System runs on a clock to help utility/grid balance load. Charges at night off-peak and discharges during peak daytime hours. Takes advantage of demand pricing to create significant savings. Grid-TRONIX SALLIE ENERGY STORAGE ARCHITECTURE 15 STORAGE SPECIFIC APPLICATIONS 1 Wind Farms - Smoothing of cut outs, wide wind speeds, & conditions 2 Wind Farms - Time Shift of wind energy from off-peak to on-peak use 3 Wind Farms - Grid Congestion Solution earns RECs & Sales offline 4 Solar Parks - Add capacity & time shifts of energy from noon to night 5 NON-Idling Instant Peaker Plant affords no fuel cost & no GHG cost 6 Power Factor Correction with Active Reactance / Capacitance Option 7 Instant storage of Load Balancing to the utility plant, with no wastes 8 Frequency Control by FERC standards using zero cost stored energy 9 Black Start Cornerstone after grid collapse & generation re-sync 10 Power Quality & Voltage Boost @ Substations & Load Centers 11 Time Shift of excess night capacity in base generation to peak use 12 Off Peak Rate to Peak Spot Rate in a Market Price Arbitrage strategy 13 Levelizing renewable generation sources from wind, tidal to biomass 14 Distributed Emergency Back-Up in Sub-Station {Generation Outage} 15 Centralized UPS for Factories, Disaster Centers, Hospitals & DOD SOLAR and BATTERY TECHNOLOGY TOP CONCERNS WHEN SELECTING A SOLAR and BATTERY TECHNOLOGY Cost Life Span Maturity Reliability Safety BATTERY TECHNOLOGY Why Lithium is the Better Choice Lithium is lightest of all metals + greatest electrochemical potential = most energy density per weight (most efficient). This efficiency leads to longer battery life (over 2x nickel cadmium and 4x lead acid). Proven chemistry common in phones & laptops Safer than Lead.

Dual independent processors located in different modules monitor other and the battery cells for unsafe and faulty operation and disconnect the contactors, isolating the battery stack when an unsafe condition is Includes protection from electromagnetic interference to ensure highly accurate voltage readings and reliable communications. System can be dually powered by the battery stack as well as via an external power source to remain operational when cells are fully discharged. This allows the BMS to maintain communications with external systems and manage the cell recharge process even from zero voltage. Modular scalable architecture enables the UtiliCell BMS to be configured to support batteries ranging from small to large energy storage system. Communicates with external maintenance and monitoring systems via Ethernet or Modbus. Firmware updates can be performed via Ethernet PREMIUM BATTERY MODULE BMS / Battery Management System Fully integrated air- and liquid-cooled battery thermal management model that provides accurate cooling and heating of module *Critical for maximization of battery performance, reliability, safety and durability EV Battery Module Cooling Plate EV Battery Module Heat Spreader Battery Cell Pouches Thermal Interface Material (TIM) Oblique Cold Plate Conditions: Temp: 30-35°C Heat flux: 0.02-0.3W/cm2 SAFETY THROUGH DESIGN UtiliCell’s “Safety Through Design” Safety-conscious design and installation that comply with latest industry codes and standards.
