1 Demand Response 2.0: transitioning from load shedding to load shaping Ross Malme Demand Response Resource Center April 19, 2011

2 From plant to plug, helping customers make the most of 5 end markets Energy and infrastructure Industry Data centres & networks Buildings Residential their energy 72% part of the worldwide energy consumption of these five markets Offering integrated solutions for segments like Electric utilities Water & waste water Oil & Gas Marine Mining, Mineral, Metals Machine builders Data centres/it Hospitals Hotels Office buildings Retail Residential

4 Power Grid only has 70 MW Power Grid needs 80 MW Power Grid pays consumers to reduce 10 MW to balance supply & demand

5 What is demand response? US DOE Demand Response Definition: Changes in electric usage by end-use customers from their normal consumption patterns in response to changes in the price of electricity over time, or to incentive payments designed to induce lower electricity use at times of high wholesale market prices or when system reliability is jeopardized. Encompasses traditional programs and ISO programs US Federal Position: It is the policy of the United States that time-based pricing and other forms of demand response.shall be encouraged, the deployment of such technology and devices.shall be facilitated, and unnecessary barriers to demand response participation in energy, capacity and ancillary service markets shall be eliminated. US Energy Policy Act of 2005, Sec. 1252(f)

7 Shifting Market Dynamics Require New Solutions 1.) Energy consumption is expected to increase as much as 50% by the year (Energy Information Administration) 2.) Generation and transmission projects will not be built fast enough to meet demand (EPRI) 3.) AMI installations will lead to real time pricing for customers as a way to pass through higher costs (FERC) 4.) Renewable generation mandates will add 20-40% to the cost of generation (AWEA) Pre 1990s 1990s - Wholesale power markets deregulate, trading starts - Independent power generators outpace utility built units - First interval data meters 2000s - Retail deregulation spreads - Utilities separate business units into Distribution, Generation and Transmission - ISOs take on roll of market pricing and clearing for generation - Renewable generation market starts in earnest Utilities outsource simple demand reduction needs to aggregators - DOE stimulus pushes AMI installations -28 states adopt renewable generation mandates for utilities -ISO and early adopter utilities push customers to complex demand programs (day ahead, real time) -CA mandates real time pricing for all C&I customers -Federal carbon program limiting emissions pending -Many new market participants enter the smart grid arena - Local utility interruptible rates for large industrials - DSM programs begin

15 Smart Grid Demand Response Evolution Dynamic Pricing Value to Utility & End Customers Low High Day Ahead Day ahead signal from utility allows building to shift loads to non-peak hours Building infrastructure allows it to react in 5 mins to utility signals Through trading partners, allows arbitrage of real time pricing markets Capacity Only Predominant form of DR in place today Building agrees to shed load at peak times in exchange for payment Called only on peak usage days (<10 X p.a.) Low Investment Required for Implementation High
