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

Next Steps

• Expand Residential DLC Pilot

• Continue testing Open-ADR technology

• 2010: Plan & launch Dynamic Pricing Pilot

• 2010: Plan & launch Large Commercial & Industrial Pilot

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
