Renewable EnergyIn one hour the sun supplies more energy than the world consumes in a year
Wind power 42% of U.S. grid capacity growth in 2012, beating natural gas, and well suited to Maryland
• Already at “grid parity” in some locations
• Major issue is transient nature of sun and wind

Enable Solar PV Generation
• Only works when sun shines- Low capacity factor and energy produced (kWh) per rated power (kW)
• Interconnect shuts system down when grid goes down- Does not provide backup/emergency power
• Battery storage shifts peak but doubles system cost without generating any more power• Genset can provide backup but with low efficiency and high emissions, noise and
maintenance• Fuel cells can generate the necessary baseload power to enable solar PV generation with
high efficiency, and negligible emissions, noise and maintenance

Distributed generation and islanded microgrids, enabled by fuel cells and batteries, will increase grid reliability and resiliency

Case study – Southern California utility
The problem : coping with high penetration of PV on feeders
Working with storage at two levels
> Substation-based (containerized)
> Small, distributed systems (Community Energy Storage)
2-3 hours of storage
Higher value closer to consumer
> But higher cost

Applications/Use Cases
• ES is absolutely key to realizing the full potential of renewables due to their intermittent nature
• Integration with renewables is but one category of uses of ES
• Total number varies by task force, but there are between one and two dozen end uses for ES which are economically viable
• One or more uses over a day is/will be common

Why care about Codes and Standards?• Business and economics
– An R&D investment is made to bring technology to the market and projects market introduction, sales and profits
– Codes and standards ‘showstoppers’ cause problems that must be addressed
– Paralleling R&D with codes and standards work fosters a more timely and better economic outcome

Uniform comparison and reporting
• Standardization will mitigate risk to investors, increase adoption of energy storage, and decrease costs through manufacturing at scale
• Standardization in ES performance allows storage mediums to be compared on a level platform
• Enables a user or customer to select which product best suits their application, which is a stated need of the market
• Lack of a uniform evaluation to determine system performance is causing confusion in the market

The Broader Standards Picture
• In addition to performance and test reporting:• Safety• Availability, reliability, maintenance• Electromagnetic compatibility• Lifetime, mean time before failure, lifecycle• Communication protocols, interoperability
• Taken on domestically via ANSI/NEMA• Taken on internationally via IEC• Cooperation with SGIP, EPRI, and other stakeholder
groups

Points for Discussion
Development of New Technologies
Technology Development and Implementation Case Studies
Reducing Barriers to Broad Implementation
Workforce Education Increasing scope
What are the proper technologies to focus upon in Maryland?
How do we address barriers to the evolution of energy storage and distribution?
How do we ensure the workforce is sufficiently skilled and trained to maintain advanced energy storage and distribution systems?
What challenges exist in coordinating energy technology growth in MD with that of the entire nation?
