21 st Century Manufacturing I Electrode Manufacturing Anode and Cathode Electrode consists of mixing, coating, blanking, and welding. II Cell & Module Assembly Sorted and stacked electrodes are brought upstairs to cell and module assembly. This station is made up of 7 major steps. III Module Fill Formation & Aging Tray Assembly GridBank Assembly IV V VI During the fill process, each cell in the module is filled with Alevolyte. Formation & Aging is a 7 step process that takes 2 weeks to complete. Four modules are secured and wired to tray and prepared for GridBank assembly. Completed parts are installed into empty GridBanks. Alevo employs over 200 at its Concord manufacturing plant. Alevo plans to hire 200 more employees and invest $300 million over next five years.

Time Shifting to Firm Renewable Energy Peaks in power prices can be shaved. Energy can be stored during low Demand Period and delivered when needed. Energy production from renewables shifted to premium price periods. This exclusive use case underutilizes the benefits of storage

GridBanks Optimize the Entire Grid Alevo is the Swiss Army Knife for the grid with tools that offer flexibility across the entire electricity supply chain GENERATION TRANSMISSION DISTRIBUTION CONSUMPTION/DG Value Proposition Revenue Producing Cost Saving Increases Grid Reliability GridBanks are Energy Source Agnostic GridBanks Offer a Range of Services Solar Ancillary Services Preserving Legacy Assets Wind Coal Oil/Diesel/Gas Peak Shaving Renewables Integration T&D Deferral Reduces GHGs, Water and Fossil Fuel Consumption Nuclear Backup Power

Alevo s First Battery Installed for Frequency Regulation in PJM 2 MW / 1 MWH battery installed for frequency regulation in PJM Installed behind the meter in Hagerstown, Maryland, in a partnership with Hagerstown Light District Alevo will install another 10 MW / 5 MWH spread across two more Hagerstown substations Remotely managed

Alevo Service Applications GridBank ESS can fulfill a broad spectrum of service applications for the grid specializing in 2 or more cycles per day Alevo Power Zone Applications less than 60 minutes. Alevo GridBanks are ideal for this heavy lifting zone. GridBanks can deliver multiple high power cycles, multiple times a day. Alevo Energy Zone Applications up to 2 hours. While capable of longer durations, the GridBank s value proposition is highest between 20 millisecond and 2-hour applications. GridBanks are ideally suited for high power applications, delivering high power within 60-minute intervals multiple times through the day without overheating or shortening their power output or cycle life.

Currently Announced GridBank Deployments In 2016, Alevo publicly announced 2 installation projects in Lewes, Delaware and Georgetown, Texas 8 MW / 4 MWh Lewes, Delaware, USA Alevo is working closely with the City of Lewes Board of Public Works on repurposing a retired oil-fired generator building. Goal is to manage and improve capacity and transmission and to better integrate wind and solar. Marks largest energy storage system in Delaware. Lewes is ranked 10 th in USA for solar penetration. The installation of the 8 MW battery will provide a significant tool to manage our capacity charges, our peak demands and transmission charges, and we anticipate it to be a boon for the citizens of Lewes. -Mayor of Lewes 10 MW / 3 MWh Rabbit Hill- Georgetown, Texas, USA Alevo to build and operate first energy storage project in Georgetown, Texas. Georgetown is first to procure 100% of its energy from renewables. Installation will provide fast response regulation services (FFRS). Project is an important milestone in evolution of the Texas market. Alevo will provide ongoing management and Operations and Maintenance services.

Alevo Energy Overview ECO SYSTEM Alevo separates itself from the competition by implementing the only vertically integrated, turn key lithium-ion energy storage solution. BATTERY MANUFACTURERS All Systems Designed To Communicate Together Reduces Failures Saves Time Turnkey Operation Lowers Costs ALEVO ECOSYSTEM PROJECT DEVELOPERS SYSTEM INTEGRATORS Battery Manufacturer Manufactures batteries which can be integrated and utilized for energy storage. Project Developer - Manages the development process of an Energy Storage Deployment by securing sites - doing the EPC (engineering, permitting, contracting) and possibly managing them. System Integrator - Builds Battery Energy Storage Systems and integrates the various components, e.g. Inverters, Batteries & Battery Management System.

Alevo Batteries vs Other Batteries Alevo Battery Technology provides unique characteristics never before seen in Lithium-Ion batteries Non-Flammable Lithium-Ion Electrolyte Alevolyte Inorganic Electrolyte vs Brand X Organic Electrolyte Alevo Battery Technology Inorganic Lithium-Ion Battery NON-FLAMMABLE Independent sources have confirmed that inorganic electrolyte cannot be ignited. 1 Other Battery Competitors Organic Lithium-Ion Battery HIGHLY FLAMMABLE Organic electrolytes are hydrocarbon based which makes them inherently flammable. Many failure modes can lead to ignition. STABLE, PREDICTABLE Inorganic chemistry remains stable over time. Behavior highly predictable. 2 UNSTABLE, UNPREDICTABLE Inherent reactivity of organic materials means that chemistry changes over time. Unpredictable. HIGH POWER High concentration of lithium-ions. Electrolyte has 10X higher conductivity than organic systems. 3 LOW POWER Only low concentration of lithium ions. Electrolyte has low conductivity. STABLE RESISTANCE High stability of electrolyte leads to stable resistance over use and time cells retain their high power capability even after 50,000 cycles. 4 INCREASING RESISTANCE Degradation of electrolyte over time leads to increasing resistance and loss of power capability.
