Why is BPA Interested in Demand Response?
• Continued load growth is leading to a forecasted capacity shortage in ~2013.
• Wind integration, fish operations, and other operational constraints are limiting the flexibility of the hydro system to meet peak demand.
• Demand Response is a proven, low-cost resource that can help BPA meet projected Capacity Constraints.

BPA Demand Response Guiding Principles
• Collaboration & Partnership: BPA will work collaboratively with our Public Utility Customers to develop and implement Demand Response pilots and programs
• Balance Cost and Risk: BPA will work to implement cost-effective, least-risk DR solutions. However, BPA recognizes that this may frequently require trade-offs between these two goals.
• Regional Leadership Role: BPA will lead by example in the region, though information sharing, collaborative research efforts, and demonstrating state of the art technology. This includes integrating Demand Response into the Smart Grid.
• Reliability & Flexibility: BPA’s Demand Response resource will primarily aim to improve system reliability and enhance flexibility.
• Environmental Stewardship: BPA will consider the environmental impacts of each DR Option.

BPA Activities in Demand Response
• Past Pilot Projects include:– Non-Wires Solutions Pilot (direct load control, back up generation)– Irrigation Pilot– Ashland Pilot (Direct Load Control)– Demand Exchange (Wholesale)
• Demand Response Potential Assessment– Developed DR Supply Curves that will be inputs into the Resource
Program• Planned DR Activities
– Research Action Plan developed– Pilot programs to test impacts and costs of various DR strategies to
meet Capacity Constraint Scenarios– Pilot programs to build regional capability

Planned Pilots
• 2009 Residential Direct Load Control
• 2009 Open ADR for large commercial
• 2010: Dynamic Pricing Pilot
• 2010: Industrial Pilot
• Considering Irrigation and Wind Integration Pilots

Open-Auto Demand Response Technology Demonstration
• Partnership with Lawrence Berkley National Labs and Seattle City Light
• First test of Open-ADR for winter peaks• Open-ADR technology interfaces with the building’s
Energy Management System to enter a custom, pre-programmed shed when notified
• Tested five commercial sites with four events per site, including one Day-Of event
• Buildings shed 8-19% of total load for morning 7-10am peak, with little to no rebound

Residential DLC Pilot• Project Overview:
•Work with 3-4 Utilities
•Leverage investments in Automated Meter Reading (AMI) systems
•Control both hot water heaters and thermostats.
•Address both summer and winter peaks
•Utilize temperature setback instead of duty cycling
•100-300 homes in first year; 700-2,500 homes in second year
•Project Goals:
• Develop strategies for BPA and utilities to work collaboratively to achieve demand response in the Northwest.
• Test integrating demand response technologies with AMI systems in the residential sector through a DLC program.
• Test recruitment strategy, customer education, and persistence
• Test costs and impacts (kW) for each capacity constraint

Where are opportunities for Regional Collaboration?
• Value in sharing ideas and results across regional utilities
• Leverage investments in research and pilots
• Share results, lessons learned
• Forum to bring in experts from other regions
