Integrated Hourly Electricity Demand Forecast For Ontario Andrzej Zerek The Itron User s s Conference September 2009 Ontario Power Generation, Energy Markets Planning & Analysis 1

ENERGY MARKETS Objective of the Presentation and Agenda Objective of the Presentation: Describe the process of generating hourly demand forecast on a weather normal basis from the current month to a long-term forecast (next 5-155 years) Agenda: Overview of OPG Demand Forecasting System/Definitions Process # 1: Producing Basic Hourly Forecast starting from actual hourly demand data to Weather Normal Hourly Profile before adjustments Process # 2: Producing Final Hourly Primary Demand Forecast including adjustments for Conservation & Demand Management, Smart Meters (TOU), Power Cost Escalation and Electric Vehicles (PHEV) Disclaimer: Some assumptions underlying the presented herein trends and analysis were primarily made for the purpose of this presentation and therefore the results dod o not represent official Ontario Power Generation views. 2

OPG Demand Forecasting System/Definitions 3 Ontario Primary Demand (PD) represents the total energy that was supplied from the IESO-Administered Market for the sake of supplying load within Ontario. It is measured by the Independent Market Operator (IESO) Total Market Demand = Generation in Ontario + Imports. PD = TMD - Exports Basic Demand is Primary Demand before the impact of Conservation, PHEV and Power Cost Escalation. The result of market forces and so includes the impact of natural conservation, technology improvements or the impact of existing standards and codes At the Customer Level Includes Self-Generation At the Generator Level excludes Self-Generation, includes Line Losses Conservation (called Conservation and Demand Management - CDM) is the incremental reduction in Basic Demand due to government programs, customer rate/price changes and enhanced standards and codes that t exceeds what otherwise would have happened as a result of market forces Energy Efficiency (EE) Demand Management (DM) Fuel Switching (FS)

OPG Demand Forecasting System/Definitions Self-Generation/Distributed Generation: CustomerC based generation also called Load Displacement Non-Utility Generation (LD NUG) Reduces demand at the customer level; part of Basic Demand Power Cost Escalation : Impact of possible strong wholesale price increases as a result of the future generation mix/contracts and/or driven by government s s policy changes e.g. carbon tax Short-term term forecast (next 14-days) is primarily driven by weather (MetrixND). Used for generation scheduling, offers to the Market and trading Long-term forecast is weather-normal (WN). Used for: Business Planning (5 years) and monthly updates. Annual energy forecast is produced once a year for BP and updated during the yeary as required Special long-term studies (up to 2027) to evaluate resource requirements and impact of various government decisions. Used as input for fundamental models: Prosym and CROP (a model developed internally) Consistency and transparency of the forecasting methodology 4

OPG Demand Forecasting System/Definitions Long-term forecast requirements: Demand forecast input required in hourly resolution (8760 for next 20 years) New challenges for the forecasters Incorporate assumptions related to: Economic drivers and sectoral forecasts (incl. natural efficiency improvements), Conservation & Demand Management (CDM), Self-Generation (distributed generation), Electric Vehicles (PHEV), Customer Rate Changes (Smart Meters/Time-of-Use rates) Power Cost Escalation Impact (price response/price elasticity of demand) Create alternative cases combining the above factors 5

Process # 1: Producing Basic Hourly Forecast Step 1: Actual Energy/OPG Weather Correction Procedure Step 2: Annual WN Energy Forecast Step 3: Monthly WN Energy & Peak Forecasts/Patterns (using MetixND) Step 4: Hourly WN Forecast/Patterns (using MetrixND) Actual Hourly Energy from IESO OPG Weather Correction Procedure Actual Weather -Dry Bulb -Dew Point -Wind Speed -Illumination Weather Corrected Energy and Peak End-Use Forecasting System for Ontario (Residential, Commercial, Industrial, Agriculture, Transportation) Base-Year Demand/End- Use Model Calibration Econometric Modeling Annual Energy Forecast derived from Monthly Forecasts Economic Data (Hstarts/H hold, GDP/GSP, Employme nt) Monthly Regression Energy Models Monthly Regression Peak Models Calendar Variables Monthly WRF (heat and cool slopes) WN Monthly Energy Forecast (Patterns) WN Monthly Peak Forecast (Patterns) WN Seasonal Peak Forecast MetrixND (Daily Energy Models, Daily Peak Models, Hourly Models) Historic Hourly Energy Data WN Hourly Load Pattern (2005 weather pattern) Weather Data Ranking & Mapping Output into the 2005 Hourly Weather Pattern Basic WN Hourly Forecast (reconciled to WN energy & peak forecast) Hourly Load Reconciliation 6

Step 1: Actual Energy/ Weather Correction Step 1: Actual Energy/OPG Weather Correction Procedure Actual Hourly Energy from IESO OPG Weather Correction Procedure Actual Weather -Dry Bulb -Dew Point -Wind Speed -Illumination Weather Corrected Energy and Peak Actual hourly demand data from IESO Weather Correction is a statistical process designed to remove the impact of abnormal weather conditions from observed load data. OPG uses it s s own WC methodology to capture impact of typically volatile weather in all seasons in Ontario. A multi-step process for weather correcting based on daily weather and energy modeling. OPG uses the last 10 years to derive normal weather Weather response coefficients are estimated using the last 2 years of data Weather Normal Peak in an interval (week, month or season) is the expected value of the maximum daily peak in that interval Summer vs. Winter WN Peak 7

In Ontario, we expect the peak on a Tuesday or Wednesday in mid July. The 2005 weather pattern: warmest day on a Tuesday, and coldest on a Saturday. For 2015, this results in the Peak on Tuesday July 14 and the Min n on Saturday July 5. The Flat WN results in the unlikely days: Peak on Friday July 17,, Minimum on Monday July 12. Flat WN vs WN obtained by ranking the daily average weather: Taking averages at the same days of the month produces a smaller variation in daily values than would typically occur over the month, consequently, a flatter load shape. Reconciling a flat shape with Peak and Min Energy forecast targets pushes many values towards either of these extremes. The WN weather pattern from ranking captures both the average monthlym levels and the expected average daily variation within the month. Produces a more realistic hourly load pattern after reconciling: fewer extremes and more of the typical mid-range values. 16
