Growth Equity Capital Raise  Opportunity Overview  February 2018 

       Executive Summary   Powin Energy Corp (“Powin”) is a commercially proven, cost-competitive, bankable energy storage system provider leveraging proven lithium-ion battery technology to capture meaningful market share in the rapidly growing (35% CAGR over next ten years) energy storage marketOver the past 8 years Powin applied their competitive advantages to the nascent energy storage sector and is currently among the market leaders in providing utility-scale and turnkey battery energy storage solutions Powin’s stack design and patented battery management technologies incorporates third-party, commercially-proven lithium-ion battery cells into large systems that help utilities and energy developers turn current and future grid challenges into opportunitiesPowin designs, assembles, delivers and operates energy storage systems; they do not manufacture any battery cells nor do they take any battery technology riskPowin has engaged Javelin Capital to raise $10 to $15 million of growth equity to: (1) build on existing revenue base to accelerate sales pipeline, (2) contribute to ongoing R&D, and (3) strengthen their balance sheet in order to provide additional comfort to customers  Opportunity Overview  Key Market Themes Driving Powin’s Strategy  Falling battery costs and emerging storage use cases have created an inflection point in the energy storage markets; Powin represents an immediate opportunity to participate in this rapidly growing industryCurrently, Powin out-prices large competitors’ by 10 – 15% through control of the entire value chain and remaining battery cell agnostic, allowing for competitive procurement of this commoditized system component Powin has secured advantageous pricing for battery cells that will significantly lower system cost in 2018 and further in 2019As the market matures, Powin’s proprietary, patented battery management system (“BMS”) will provide deeper insights into cell behavior than competitors and provides a flexible platform for value-add applications that evolve with customer needsWhile most competitors provide select components of an energy storage system, Powin delivers turnkey, fully integrated, and bankable energy storage systems  Powin’s Position in the Market  1  2  3  Powin is ideally positioned in the rapidly growing energy storage market driven by falling costs and renewables integration  Powin’s model exploits the continued falling cost of lithium-based battery technologies  Powin captures technology, price and scale benefits from billions of investments into manufacturing facilities largely driven by the electric vehicle market  Lithium-ion Battery Historical and Projected Cost Curves ($/kWh)2  Forecasted Cumulative Global Lithium-ion Manufacturing Capacity (GWh)2  Sources: 1.

         Competitive Position and Competitive Advantages   Bankable Technology: Powin has secured non-recourse project debt from Brookfield Renewables; financial partners, customers, utilities and expert consultants know that the Powin BESS works Current Substantial Market Share: Powin validated market acceptance of its technology with a 9 MWh operating project and 46.8 MWh under construction within one of commercialization Sophisticated and Low-Cost Procurement Supply Chain: Powin’s U.S. and China-based teams maintain an advanced supply chain in Asia to identify and qualify the best value, best fit commercial lithium-ion batteries and components; Powin’s affiliated manufacturing facility in China allows continual cost, quality, and delivery improvements‘Future Proof’ Technology Solutions: Powin is cell chemistry agnostic which coupled with strong relationships amongst battery manufacturers provides three distinct advantages: (i) low system cost through a competitive procurement process, (ii) flexibility to select batteries based on customer specific needs, and (iii) no exposure to a single battery chemistry or manufacturer Ideally Placed to Maintain Market Share: Current business development efforts are focused on direct system sales to North American energy developers, currently with $250M of probability adjusted sales opportunities (one of the largest in the industry): Leveraging Partnerships for Further Growth: Powin is building sales channels with utilities, IPPs, C&I developers, and in fast growing international markets  Vertically Integrated Platform  Key Investment Highlights  Powin’s Value Across the Supply Chain  Modular Core Product:Allows rapid and low cost installation across utility and C&I applications in indoor or outdoor environments  Powin Battery Management System:Proprietary BMS employs sophisticated monitoring and controls reducing operating costs, improving system safety, and extending cell life  Powin Applications Layer:Utilizing detailed BMS data, Powin engineers value-add customer applications, opens new markets, and creates additional revenue streams  Sustained Advantage Relative to Competitors        No Captive Battery Cell TechnologyFully integrated battery cell manufacturers are captive to their own cell technology, causing them rigidity on price and exposure to commodity pricing risk; Powin has the flexibility to use multiple cell providers and chemistries to drive down costs and avoid supply constraints  Capture More of the Value ChainBattery Integrators focus on the final installation and delivery of energy storage systems for projects; this limited portion of the value chain threatens their sustained margins while Powin can capture more value by providing this as a piece of its offering   Insight to Continuously InnovateSoftware providers create applications and integrations that sit on top of other vendors’ technologies, but without Powin’s deep analytic insight of batteries on the cell level, these firms will struggle to create effective products  Operating  In-Construction  Booked Sales  Proposal Stage  Identified  9 MWh  46.8 MWh  66 MWh   1,000+ MWh  1,000+ MWh  Powin Assembly and Integration:Flexible manufacturing processes allows optimal design and integration of full turnkey solutions to meet evolving market demands
