2 Rural Alaska is Unique 2

3 But Similar Challenges Exist Globally 3

4 We ve Come A Long Way ~26 Wind-diesel projects installed or under construction >95% renewable in Kodiak Beginning of smart grids, load control, optimizing dispatch strategies, wind-toheat, high penetration hybrid systems Displacing (some) diesel BUT Technical, institutional, financial and other challenges remain, eg, Systems are very high cost, customized, often underperforming Limited support, data analysis, agreement on development path 4

5 Remote Community Renewable Energy Partnership Department of Interior led initiative High contribution renewable energy hybrid systems in remote locations Target markets Ø Islanded systems geographically and/or electrically (high cost/ diesel dependent) Ø Circumpolar north Ø Tropics Ø More Locations = More Markets = More Opportunity = Lower Costs Relevant Technologies Ø Wind, especially in Arctic Ø Solar, especially in Tropics Ø Biomass? Hydro(kinetic)? Ø Energy Storage 5

6 RCRE Partnership, continued Modular and Replicable Ø Control systems Ø Communication protocols Ø Interface Ø Storage Ø System Integration ECONOMIES OF SCALE AIM TO DRIVE DOWN COSTS CREATE PRIVATE INVESTMENT OPPORTUNITIES 6

7 Who Is Involved? Partners Ø NREL Ø University of Alaska Fairbanks Alaska Center for Energy & Power Ø Colorado State University-Engines & Energy Conversion Lab Ø US State Department Ø Several others in discussion, including end-users, private industry (technology & project developers, system integrators), other national governments in circumpolar north and tropics, utilities, investors 7

8 RCRE Project Activities Design Basis Framework Phase I 75% diesel displacement for electricity and heat in circumpolar north 75% diesel displacement for electricity (including cooling) in tropics Pilot Projects Phase II Incorporate Lessons Learned à Deployment! - Phase III 8

9 Phase I, expanded (2014) 1. Refine Design Basis Framework Is 75% diesel displacement realistic? (including heat in arctic, cooling in tropics) What will this entail (e.g., diesel off, storage, dispatch strategies) Scalable? Or Replicable? Or Both (Community/Load size) 2. Workshops Communication protocols Performance parameters Develop Roadmap Diverse Participants 3. Specify Module System Requirements Model Scenarios 9

The on-board power electronics include PV Maximum Power Point Tracking (MPPT) converters, battery charge/discharge converters, and a three-phase inverter capable of smoothly transitioning between operation as a stand-alone voltage source and operation in parallel with the diesel generators or a utility grid connection 10
