Overview of Environmental Pressures
EPA is in the process of promulgating a series of new regulations tocontrol (or tighten existing controls of) the following effluents:
Criteria air pollutants especially NOx, ozone, SOx, and particulates
Hazardous air pollutants (HAPs), especially mercury
Cooling waterimpacts of intake structures
Coal combustion byproducts ash disposal pathways
Greenhouse gases (GHG) primarily CO2
from new and modifiedsources
Or, potential legislation in the future to implement a federal climate policy
Emerging regulations will require existing coal units to either retrofit(install environmental control equipment) or retire
Near-term compliance with SOx, NOx and mercury regulations
Coal ash and water regulations (316b) may be delayed, and GHG rulesmay be litigated

EPA Rules and Timelines
Clean Air Transport Rule (CATR) Regulates NOx and SOx emissions frompower plants in 31 states
Proposed in 2010; Final rule June 2011; Implementation starts 1/1/2012
Reduces SOx emissions by 71%, NOx emissions by 52% (relative to 2005 levels) Many existing units will need to add expensive scrubbers and SCRs or retire
Mercury /HAPs Requires oil and coal-fired power plants to install controls:Maximum Achievable Control Technology (MACT)
MACT rule proposed in March 2011; Final Rule November 2011 Compliance 3-4 years after final rule (2014-2015)
Coal Ash Regulates coal ash disposal Final rule in 2011 Implementation 2014-2018
Clean Water Act Regulates cooling water intake structures Proposed March 2011; Final Rule July 2012 Compliance possibly up to eight years after final rule (2020)

Announced Coal Plant Retirements
Several coal plant owners have announced retirement of coal units between2010-2020
Retirements offset by new coal units coming on-line between 2009-2012
(approximately 16 GW) Few retirement announcements in Northeast Salem Harbor (MA) may retire in
2014; AES Thames (CT) has declared bankruptcy (but has not retired)

Brattle Coal Plant Retirement Study Key
ConclusionsA requirement to install scrubbers and SCRs on coal units by 2015 would result in 40-55GW of economic retirements beyond the 6 GW projected without new mandates
Another 11-12 GW of coal units would retire ifcooling towers (@ $200/kW) are also mandated
Higher-end of range based on doubling the retrofit costs due to potentially increasing demand for labor and controlequipment or due to site-specific constraints
$70-130 billion investment on scrubbers and SCRs (for 187 GW coal capacity) would beneeded to comply with the EPA mandates
An additional $30-50 billion compliance investment would be needed ifcooling towers are also mandated.
Most of the economic retirements are with merchant units (which rely on marketrevenues), in contrast to regulated units whose retirement decisions are based on the
cost of replacement power

Potential Impact of CO2 Price on Coal and
Gas Dispatch Uncertainty with respect to climate policies creates additional risks for coal plantsa CO2
price under cap and trade would put additional pressure on coal plant economics
$1/ton CO2 $1/MWh of coal-fired, $0.40/MWh of gas-fired power cost
Dispatch switching takes place between gas and coal starting around $10/ton CO2 (at $6
gas price) and eliminates conventional coal by ~$80/ton

U.S. Gas DemandResidential/Commercial
Little growth in residential/commercial demand since 1980
Declining residential use per customer due to improved appliance and buildingefficiencies, and impact of higher prices
Gas energy efficiency budgets more than quadrupled recently, from $250 millionin 2006 to over $1.1 billion in 20103
Gas energy efficiency budgets in New England/NY/NJ ~ $350 million in 2010

Historically, growth in electric power use of gas has roughly offset the decline in industrial load
EIA now projecting industrial gas demand growth of 4.5 Bcf/d by 2020 due to economicrecovery, growth in combined heat and power, and low gas prices
Low gas price assumption is keywill prices stay low (in a shale gas world) if electric sectordemand increases substantially in next 10 years? How would a CO2 price impact industrialdemand for gas?

Gas Demand and Renewables/Conservation
29 states have a renewable portfolio standard (7 states with non-binding goals) Renewable energy development starting to reduce gas demand for power generation
Renewables are must-take, pushing out whatever fuel is on the margin In many regions, gas predominantly on the margin (e.g., 90% of the time in ERCOT)
15,000 MW of wind energy added in 2009-2010 (EIA forecasts no wind additions after
2012) Total renewable energy generation (including hydro) expected to grow from 370 billion
kWh in 2010 to 500 billion kWh in 2015 (50 billion kWh ~1 Bcf/d of gas demand) 23 states have energy efficiency resources standards (% reduction targets in energy
use) also reduce gas demand if gas on the margin

Other Low Carbon Technologies (beyond 2030)
Will there be a nuclear revival in the U.S.? U.S. NRC now actively reviewing 12 license applications for 20 new
nuclear units
Lack of carbon price will hinder development Loan guarantees and subsidies needed for new nucleardevelopment
Impact of recent events in Japan on U.S. nuclear relicensing
Carbon capture and sequestration In the RD&D phasetiming of CCS deployment very uncertain Lack of carbon price will hinder development If focused on coal, would limit gas demand growth But gas CCS also possible
Given these limitationsgreat opportunity for natural gas inthe electric power sector over next 20+ years (and anopportunity to lower CO2 emissions)

Long-Term Prospects for Gas Demand
Gas demand and prices affected by multiple, sometimesconflicting, pressures resulting from
Regulatory policies related to CO2, renewables, and energy efficiency
Availability of low carbon technologies (CCS and nuclear) CO2 prices (prices for allowances and offsets) Potential for coal plant retirements due to EPA regulations (SO2, NOX, etc.)
Among these positive and negative influences:
(+) Coal plant retirements(+) Coal to gas electric dispatch substitution under cap & trade
(+) Gas back-up for renewables
(-) Renewables displacing gas in electric sector
(-) New generation technologies (nuclear, CCS in outer years)
(-) Non-electric gas demand reaction to increasing prices
(-) Energy efficiency for gas and electricity
Volatility results from opposing pressures at different times

22/25
22
Summary
Coal plant retirements due to SO2, NOX and other potential EPAregulations could result in substantial gas demand growth thisdecade and result in upward price pressures
Natural gas vehicles boost gas demand only in substantialdeployment scenario with policy intervention
Potential challenges to natural gas demand growth:
Emphasis on renewables and electricity conservation reduces gasdemand in regions where gas is marginal fuel for electricitygeneration
Non-electric gas demand growth likely to be low due to retailconservation programs and price impacts of CO2 policy that may
negatively impact industrial gas demand
High CO2 prices needed for coal to gas switching under cap andtrade may not be forthcoming this decade
Long-term gas demand growth more likely if deployment of
renewables, nuclear and coal w/CCS is limited
