What is a Demand Responsive Building System? EMS or building manager who responds to price or emergency signals by reducing building loads ( HVAC & lighting) Building manager takes advantage of opportunities to sell load reductions to aggregators, UDC’s, or the ISO

CALIFORNIA ENERGY COMMISSION CEC Program Objectives Empower customers to save money and reduce peak reliability problems next summer Encourage customers to install control systems that can respond to price or “emergency” signals and communicate load reductions achieved to ISO Install systems capable of saving 50 MW in response to signals by June 1, 2001

CALIFORNIA ENERGY COMMISSION CEC Program Approach Provide metering equipment and assistance to enable customers to participate in ISO/utility programs using recruitment contractors Provide direct grants to larger customers who have the engineering knowledge to install own systems

CALIFORNIA ENERGY COMMISSION Contracts Awarded

CALIFORNIA ENERGY COMMISSION Grants Awarded

CALIFORNIA ENERGY COMMISSION Why Install Demand Responsive Systems? Cheaper than building emergency backup ($50-250/kw installed) Markets do not work without demand responsiveness to respond to high prices Need to monitor and control energy costs and to automate EMS responses

CALIFORNIA ENERGY COMMISSION New Funding Possibilities SB 5x has $70 million in funds for new demand responsiveness programs AB 970 programs were over-subscribed by $5 million so new funds will augment existing applicants first
