  5. Greater energy efficiency and conservation are vital near-term and long-term mechanisms for moderating price levels and reducing volatility Power generators and industrial consumers are more dependent on gas-fired equipment and less able to respond to higher gas prices by utilizing alternate sources of energy Gas consumption will grow, but such growth will be moderated as the most price-sensitive industries become less competitive, causing some industries and associated jobs to relocate outside North America Findings on Natural Gas Demand

  6. Recommendations Related to Natural Gas Demand Objective: Improve demand flexibility and efficiency Recommendation #1 Encourage Increased Efficiency and Conservation through Market-Oriented Initiatives and Consumer Education Recommendation #2 Increase Industrial and Power Generation Capability to Utilize Alternate Fuels

  16. Industrial Demand Approach • Industrial demand for natural gas particularly driven by a discrete group of industries • Chemicals, refining, food, paper, primary metals, stone/clay/glass • Model focused on these industries • Analysis focused on primary industrial uses of natural gas • Feedstock • Boiler Fuel • Process Heating • Other (space heating, cogeneration, on-site electricity generation) • Demand forecasted from • requirements for each end-use • intensity (gas use per unit of output), reflective of technology mix & fuel switching • Capacity idled in modeling for at least two years is assumed to be shut down permanently

  17. Insights on Most Gas-Intensive Industries • Chemicals • Feedstock, steam and process heat • Demand growth driven by cogeneration, hydrogen needs • Ammonia, methanol, ethane-based ethylene experiencing shutdowns • Petroleum Refining • Steam generation and process heat • Demand growth driven by hydrogen, cogeneration, heavier crude feedstocks • No new refineries expected, but industry expected to maintain full capacity • Paper • Steam generation and lime calcining • Demand growth driven by cogeneration and and process reconfigurations • Increased mill production driven by demand for paper and paperboard • Primary metals • Process heating • Lower demand and increased competition from imports • Consolidation and plant closures

  18. Industrial Demand Workshop Observations • Outreach efforts indicate relatively gloomy picture of expected industrial growth • reflective of current economic downturn • concerns for long-term viability of some industries • Gas price not the primary driver in many industries • keys: labor, raw materials, proximity to market, exchange rates, financing arrangements/loan guarantees • for consumer products (e.g., toilet paper, wallboard), higher gas prices mean higher consumer prices • Regulatory limitations exist to energy-intensive retrofits • Bulk paper industry seeks continuation of PURPA or similar enabler to CHP

  19. Fuel Substitution Capability • Public information presents optimistic view on fuel switching capability • Fuel switching inhibited by local siting restrictions and State/Federal air standards, multiple examples cited by range of industries 26%* Natural Gas and Oil-Based Industrial Consumption 5-10% 1995 Today *EIA/Dept. of Commerce MECS Survey

  20. Industrial Demand Workshop Observations • Energy-intensive commodity industries not growing • international competition from areas with “stranded gas” and/or emerging markets and/or other factors • temporary/permanent displacements of capacity planned/possible due to relative price differentials • gas-intensive ammonia and methanol capacity will decrease step-wise with time • primary metals (steel, aluminum) will not grow except in ‘planned economy’ such as Quebec • no new refineries or petrochemicals facilities seen • no new chlor-alkali facilities seen • Outreach efforts consistently reflected • concerns over recent natural gas prices • belief that continued higher prices are detrimental to industrial sector • less demand responsiveness than in past due to environmental (emissions) restrictions and gas-favored process investments • fundamentally different downstream market for products (less liquid, less transparent than electric power, for example) • effect of non-domestic factors on natural gas demand (world markets, emerging economies, proximity to stranded gas, etc)

  25. Power Generation Demand

  26. GDP Effects Demand for Electricity Driven by GDP; Future Gas Demand Driven by Power • Electricity demand growth is strongly correlated to GDP growth • Electricity demand grew faster than GDP in 1950’s and 1960’s • Rate of growth declined to a ratio less than 1.0 in mid-1970’s • Declining energy intensive manufacturing industry • High oil / energy prices • Increased efficiency • Saturation of electric appliances • Ratio factor approximately 0.72 • Gas fueling more hours of power generation will couple gas demand to power and to its GDP relationship • Combined cycles influenced more by GDP driven demand • Combustion Turbines tied more to weather induced demand

  29. Gas Demand Will Grow But Coal Still Plays Major Role Electricity Generated by Fuel Type, TWH/Year Renewables Gas Oil/Distillate Coal Hydroelectric Nuclear

  30. Modeling Assumptions for New Generation Capacity • Model called for new capacity when reserve margins hit threshold • No coal built on West Coast or in EPA non-attainment areas • Additional coal built beyond reserve margin test if economics support • New coal limited in Florida • Total new coal limited to 14 GW per year • Renewable generation capacity is able to economically compete • Differing alternate fuel capability between cases • Post-run processing to ensure emissions limits not exceeded

  31. New Generation Capacity Technology Assumptions

  32. Other Modeling Assumptions Related to Electric Power • Load growth remains coupled to GDP growth • Growth ratio changes from 0.72 to 0.62 in Reactive Path • Growth ratio changes from 0.72 to 0.55 in Balanced Future • Hydropower capacity unchanged; annual generation multi-year average • Nuclear plants have success in 1 relicensing effort • Capacity increases by 2% in Reactive Path • Capacity increases by 10% in Balanced Future • Capacity factors remain above 90% in future • Mercury regulations cause 20 GW of coal fired capacity shut-down in Reactive Path • Older oil/gas steam units continue retiring through 2010 • Transmission capacity between regions increases by 50% over study period • No attempt to model market rules, market designs, transmission congestion, or locational marginal prices

  33. Sensitivities Related to Electric Power • Directly coupled sensitivities • High and Low GDP growth • High and Low ratio of electric load growth to GDP Growth • Fuel Flexibility • Carbon reduction • Indirectly coupled sensitivities • Weather sensitivities • Higher oil price

  37. Efficiency of Gas Use Has an Impact Annual Heat Rate Total Gas Fired Generation • More efficient gas fired units use less natural gas • ERCOT Region • Example: AEP and Centerpoint decommission less-efficient steam units, ~6,000 MW mothballed • 50% Capacity factor • Average Heat Rate of 12 MMBtu/MWh • Combined Cycle heat rate of 7 MMBtu/MWh • Annual gas savings ~130 Bcf • Other considerations keep older steam units in dispatch • Voltage support in congested area • Regional system reliability • Alternate fuel capability • Regulatory compacts at state level Source: EIA STEO Data
