Brandon Shores Plant

• Two 640 net MW pulverized coal units

• Unit 1 – 26 years & Unit 2- 19 years in 

Operation

– Drum Type Boilers operated at 

2600 psi

 produces 4.4 Million lbs/hr of 

steam

– Highly Efficient Turbine-Generator

– Uses 3.5 M tons of coal each year

 Rec’d by barge, pulverized

– Produce 6-8.5 Million MWs 

annually

4
Designed with the Environment in Mind

• Units circulating water utilizes cooling towers to 

minimize heat load on the Patapsco River

• Hot Side Precipitators remove 99.4% flyash

• Partnership with STI beneficial re-use of 85% flyash

– Over 2 Million tons utilized in concrete

• Low NOx burners, Over-fired air

• Selective Catalytic Reaction (SCR) 

– 90% NOx reduction

– Urea supply converted to ammonia for community safety

• 30-60M gal of plant wastewater recycled each year

• Sedimentation & Erosion control ponds to minimize 

stormwater run off

 95%

Mercury 

 emissions are 

 expected to be 

 reduced by 

 90%

The preconstruction and construction process moved forward 

smoothly because Constellation anticipated stricter federal 

regulations and prepared accordingly

CONSTRUCTION PROCESS

9
Conceptualization of the project prior to the 

passage of Maryland’s Healthy Air 

Act (HAA) in April 2006

• Engineering, design, contracting, procurement, planning, 

and layout commenced while the regulations were being 

finalized

• Total time from the initial planning to the completion of 

construction was under four years (January 2006 through 

September 2009)

• Constellation started the design and permitting process prior 

to regulations being final

10
Pre-engineering steps should be taken now

– Costs associated with this pre-engineering are not 

onerous, and prudent generators can expend these funds 

as part of developing an integrated environmental 

compliance strategy. 

– This advance planning will also allow companies to better 

control costs and establish a cost effective schedule for 

constructing and installing any necessary control 

technologies. 

• Thus, while some companies are now suggesting 

there will be widespread need for additional time, 

many of those requests will be unnecessary if 

companies can begin now to prepare for 

compliance.

11
Significant Economic Benefits for the Region

• Constellation's total 

investment was $885 

million

• At peak construction, 

1,385 personnel on site at 

one time

– skilled craft and construction 

workers including 

boilermakers, steamfitters, 

pipefitters, operating 

engineers, millwrights, 

ironworkers, electricians and 

master electricians, as well 

as carpenters, teamsters, 

and laborers.

12
1600 job-years to build the AQCS

• Outstanding safety 

performance

• 4.3 million man hours

• worked closely with the 

Maryland and DC 

building trades and other 

unions

• does not reflect the 

associated 

manufacturing jobs

13
AQCS Project Combined Construction Labor Hours

14
Economic Benefits of the Manufacturing Jobs

• The manufacturers of 

the cranes and vehicles 

deployed on site

• Manufacturers of the 

many large and small 

components ranging 

from booster fans, 

pumps and pump 

motors, to ball mills, 

electronics, wiring, 

steel, concrete, and 

specialty tiles for the 

flue gas stack

• Thousands of individuals to 

make these goods and 

operate the companies that 

form the supply chain for this 

kind of infrastructure

15
• Empirical evidence of 

man-hours hired and 

paid;

• Emissions measured 

and lowered;

• Megawatts successfully 

produced and bid into 

the markets.

It is this experience that give us the confidence that we our 

sister companies in the electric power industry can continue 

to deliver affordable electricity with the great reliability all 

consumers depend upon, while also meeting the air quality 

requirements set forth in the Clean Air Act.
