2 Smart Grid Overview How do we define the Smart Grid The application of technology to upgrade and improve the electricity gridPreviously SG was Advanced Metering Infrastructure (AMI / smart meters), now first step is often Demand Management or Distribution Automation.Smart Grid uses technology and business models to improve control, efficiency, and reliability of the electricity grid.Some Popular DefinitionsWikipedia:“A smart grid delivers electricity from suppliers to consumers using two-way digital technology to … reduce cost and increase reliability and transparency.”DOE:“Smarter grid”: Near-term, focused on data and communications within power system“Smart grid”: Long-term, focused on transforming the way we use energyCommonwealth Edison Executive:“A scratch for whatever itch you may have.”
3 Why do we need a Smart Grid? A smarter grid applies technologies, tools and techniques available now to bring knowledge to powerEnsuring its reliability to degrees never before possible.Maintaining its affordability.Reinforcing our global competitiveness.Fully accommodating renewable and traditional energy sources.Potentially reducing our carbon footprint.Introducing advancements and efficiencies yet to be envisioned.Underinvestment in grid infrastructure - 60% of US power grid needs to be replaced within 10 years40% more power outages in second half of 1990s compared to first halfNumerous government programs that view grid improvement projects as a method of stimulating the economySlow down in development of large-scale generation facilities due to cost & environmental impactsCapital expense avoidanceShifting of small % of energy usage = lots of savingsSurgical Deployment – address high impact opportunities early in the processPower system disruptions cost US $100 billion a year30% increase in demand for electricity from 1988 to 1998; 20% from 1999 to 2009Improved customer serviceMeet regulatory requirementsPositive environmental impact leads to ‘Green PR’Coal generates 54% of US electricity, and is the single biggest air polluterUnclean energy needed to meet capacity accounts for approx. 15% of GHG emissionsFuel generation also causes groundwater contamination and land disruptions thru mining and exploration
4 Why is this happening?Hundreds of thousands of high-voltage transmission lines course throughout the United States, only 668 additional miles of interstate transmission have been built since 2000.As a result, system constraints worsen at a time when outages and power quality issues are estimated to cost American business more than $100 billion on average each year.US DOE
5 Regulatory Actions Act 129 - Pennsylvania Act 129 directed that all electric distribution companies with at least 100,000 customers are to file an energy efficiency and conservation planRequires a 4.5 percent reduction (1,193 MW) in peak demand by May 31, 2013The utility could be fined up to $20 million for failing to meet these reduction targets.

7 Financial Implications Why is this important to businesses – beyond social implicationsThink about the scale# of endpoints on network increasingInterval data updatesThink about costsA small change in peak demand can lead to significant cost savingsThink about benefitsPrograms typically target 3% - 6% reduction in energy; depends on specifics of programBenefits of the Smart GridFinancial benefits to implementing DM are the main driver for the industry. Some other benefits are:Offset the need for peaking capacity – capital expense avoidance/rate increasesDecreased operational costsReduce the need for additional transmission and distribution networks.Enable federal, state, local governments to obtain emissions reduction goals; meet regulatory actions and avoid penalties or take advantage of incentives.“Green PR” – utility and its customers perceived favorably as contributing to the environment.Substitute the need for additional generation capacity, lowering green-house gas expenditures.Prepare for ‘What’s Next’
8 Trends and Transformations Technology has evolved rapidly: - Smart Meters more sophisticated and reliable - Costs have decreasedMany early adopters abandoning original AMR systems: - Features that were once uneconomic & unproven now cost-effective, reliable and practicalDriving ChangeBusiness case justifiedCosts reasonableBenefits quantifiableSkilled workers retiringConservation a necessityCo-opetition among vendors
9 Goal: Balanced Demand TYPICAL DAY PEAK DAY Direct Load Control Utility forecasts how much energy it expects to use on a given dayPurchases energy slightly in excess of forecasted peak demandTypical peaks morning & evening; more costly to produce energy during these high-use periodsPeak DayEnergy consumption spike usually caused by unexpected hot/cold temperaturesAppliances & HVAC forced to work harderTwo tough choices: - Spot Market: purchase energy that is often x higher than retail; costs & greenhouse gas emissions rise - Shed Load: brownout; inconvenience customersCONSERVATIONFORECASTED USAGE::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::COST / kWhEMISSIONSComparison of typical day to peak dayTHREE FLAVORS OF DRDirect Load ControlAllows utility to quickly shed load during emergency conditions or to avoid high peak energy pricesLoad decreased or curtailed during peak event: - pre-defined HVAC settings for time and/or temperature offset - on/off or cycling of appliances: water heaters, pool pumps, etc.User over-ride optionUtility directed program with voluntary consumer participationTOU PricingUtility establishes energy price levels for different times of the day including weekdays / weekends or seasonal adjustmentsUtility notifies consumers when price levels are in effect, e.g. peak, mid-peak and off- peakAppliance can be set to cycle down or shut off during high energy price periodsCheaper energy during off-peak periods motivates consumers to move non-essential energy use to off-peak timesVoluntary or mandatoryDynamic PricingVariable pricing levels determined by supply and market conditionsCurrent energy price presented on In-Home Display – rates adjusted periodically or dynamicallyAppliances can be set to automatically shut off / cycle down during peaksEnables a utility to match its retail costs with fluctuating wholesale costOptimizes supply and demand on a real-time basisTYPICAL DAYPEAK DAYOver 50% of a utility’s annual power costs can be incurred within 10% of operating hours.MORNING PEAKEVENING PEAK1:00 | 2:00 | 3:00 | 4:00 | 5:00 | 6:00 | 7:00 | 8:00 | 9:00 | 10:00 | 11:00 | 12:00 | 13:00 | 14:00 | 15:00 | 16:00 | 17:00 | 18:00 | 19:00 | 20:00 | 21:00 | 22:00 | 23:00 | 24:00
10 Goal: Balanced Demand BALANCE CONSERVATION Goal 1: flatten the peaks by moving some consumption to periods where energy is more abundant and cheaper to produceGoal 2: shed load on specific devices (air conditioners / pool pumps) rather than enacting full-scale brownoutsGoal 3: signal customers when different price levels are in effect so they can better manage household usage and reduce costsCONSERVATIONFORECASTED USAGE::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::COST / kWhEMISSIONSBALANCEMORNING PEAKEVENING PEAK1:00 | 2:00 | 3:00 | 4:00 | 5:00 | 6:00 | 7:00 | 8:00 | 9:00 | 10:00 | 11:00 | 12:00 | 13:00 | 14:00 | 15:00 | 16:00 | 17:00 | 18:00 | 19:00 | 20:00 | 21:00 | 22:00 | 23:00 | 24:00

20 PROGRAMMABLE THERMOSTAT :: ST-1480 Communicating Smart Thermostat to Maximize ConservationCustomizable, feature-rich Demand Response device for customer signaling, load control & a full range of conservation programs.Highly configurable & customizable – implement desired rate structures, load control programs, user messaging and over-ride permissionsSupports over-the-air upgrades and programming via TUNet to extend features and change operating parametersReliable communications, self-initiating & self-healing association within the TUNet LAN; optional ZigBeeBright visual alerts notify consumers when load shedding is active and when low, medium or high energy price in effectFunctions as a standalone device or in conjunction with other TUNet-enabled meters or load control switchesConfirms commands; time-stamped messages verify start & stop time for accurate billing and regulatory reportingWorks with both residential and C&I loads: – HVAC air conditioners and heat pumpsTUNet PRODUCTSST-1480 Programmable Smart ThermostatThe ST-1480 Programmable Communicating Thermostat is an end-to-end Demand Response solution that gives utilities a fast, affordable and highly effective way of curtailing system loads and interacting with customers in energy conservation programs.The ST-1480 is more than a smart thermostat. It is an interactive DR tool that gives a utility central control over HVAC units at residential and C&I accounts. It also displays up-to-the-minute curtailment notifications and price alerts so consumers can see when load shedding events and peak energy rates are in effectIt also displays up-to-the-minute curtailment notifications and price alerts so consumers can see when load shedding events and peak energy rates are in effect.Tantalus designed the ST-1480 as a two-way, utility/consumer communications tool that can be customized, configured and upgraded to fit each utility’s DR program. It supports multi-tier, Time-of-Use price signaling as well as load control so a utility can take action to avert a system crisis. Time-stamped records verify start & stop time and provide the data needed for accurate billing and regulatory reporting.It can also serve as a Home Area Network (HAN) gateway via TUNet or optional ZigBee. Advanced applications such as messaging can be incorporated which enable a utility to communicate directly with its customers and provide easy access to household billing and consumption history.The ST-1480 features an intuitive console and large LCD panel. Tri-color indicators (green, yellow, red) can be configured to glow when an event is in effect and to display the degree of importance as defined by the utility. For example a red light can signal a critical peak and high rates. With the push of a button, a consumer can opt-out of a shedding event.Operating ranges such as thermostat set point and scheduling preferences are easily adjusted. The ST-1480 can be programmed to automatically regulate the temperature when certain rates are in effect. An optional “conserve mode” allows customers to instantly change the temperature to a pre-set level and begin saving energy and money.Installation is easy; an ST-1480 simply replaces the existing thermostat. Communication via TUNet is automatically established. Over-the-air programming enables a utility to configure devices remotely. Altering price alert levels, adding functionality or moving a customer to a new DR plan can all be done from the utility’s operations center via a web application.A utility can leverage TUNet and the ST-1480 to drive Smart Grid functionality and implement a full range of emergency, environmental and economic DR activities to whatever degree it desires. The ST-1480 closes the communications loop with customers and is the cornerstone of year-round load management and energy conservation programs.
