Question 3

key issues in 2013 for P94?

Answer 3

1. safety and reliability
   a. high profile incidents magnify risks
   b. standard approach to mitigation can address risk
2. product integration
   a. technology is maturing, but integrated solutions are nascent, early stage, hard to go out and procure battery simply with a boiler plate specs, b/c not a lot of products have been deployed, ESIC
3. tools to assess value of storage. more to be done in ESVT
4. informing the government
   a. policy initiatives are opportunity and challenge
   b. storage as a business arise from regulatory treatment of storage
   c. EPRI is stand ready to inform when requested, from a technical standpoint.

Question 8

what is cost and technical capabilities of energy storage project?

Answer 8

deliverable: cost and technical capability of energy storage (cost database).
approach: conduct technology deep dives on individual technologies to understand present and future costs and capabilities. focus on lithium ion batteries this year

Question 9

What is 94.002?

Answer 9

1. Distributed ES options for Power Delivery

Question 10

what is distributed ES options for Power Delivery

Answer 10

1. promote standard terminology
   one: distribution energy storage technology reference guide (satish)
   - -create reference materials for utilities to specify procure install and commission safe and reliable distribution ES
   - -materials include reference technical specs, test plans, test results as available
2. distribution energy storage integration guide (ARINDAM MAITRA)
   - -integration of the storage product with the grid
   - -can call it interconnection
   - -develop analytical tools to predict how storage affects the grid
   - -continuation of openDSS
3. Distribution ES with PV systems–case studies
   - -describe field testing of two ES systems at solar TAC facility in Denvor, CO
   - -solar-2-battery (S2B) Lead Acid
   - -Community ES project SODIUM NIC
4. Peak Load Management of Thermal Loads using Advanced Electrothermal Technologies
   - -2013 lab testing efforts
   - -Ice energy
   - -energy storage capacity of 2 Ton-hr
   - -Hot water
   - -deployed in Britain, trying to get it in to Knoxville

• -Demonstration of 36mw/24mwh advanced lead acid battery at 150MW wind farm (notree) Steve Eckroad, deploy xtreme power battery at notrees winde farm

Question 12

supplemental: battery storage systems and applications demonstration

Answer 12

• Dan
• deploy a prototype system built according to a spec developed collabroatively by utilities
• -apply standardized analytical tools to assess grid impacts and benefits
• deploy the system that was build with the specs
• -old lithium ion demo
• -utility brings their own systems, joins collaborative, everyone share the experience with everyone.
• -taking storage systems from community size to mw scale
• -international representation

Question 13

supplemental two: assessment of grid benefits of fuel cell at utility substation

Answer 13

• dan
• case study to look at performance metrics
• efficiency, reliability availability
• -3MW solid Oxide Fuel Cell on utility substation
• -collaborate with bloom energy and delmarva power -the host utility

Question 14

Supplemental: tool for distribution level energy storage assessment and integration

Answer 14

case study based distribution level energy storage assessment
apply tool to participant utilities
develop and validate impact/value integration specification framework
