Nuclear Energy in
Japan
• 54 operating nuclear reactors (49 gigawatts)
• Two nuclear plants under construction
• Tokyo Electric Power Co. produces 27% of Japan’s electricity
• 12,000 MW of nuclear energy capacity shut down
Fukushima Daiichi Nuclear Power Plant
Before the Accident
Unit 1
Unit 2
Unit 3
Unit 4
Units 5, 6
At the time of the earthquakeReactors 1, 2 and 3 operating
Reactors 4, 5 and 6 shutdown for maintenance, inspection, refueling
• Earthquake occurs at 2:46 p.m.– Power grid in northern Japan fails
– Reactors are mainly undamaged
– Reactors are automatically shutdown as designed
– Power generation stops - subcritical
– Diesel generators start, providing back-up power to emergency systems
– Emergency core cooling systems are running
– Plant is in stable condition
Timeline of Events
• Tsunami hits plant at 3:41 p.m. (less than 1 hour later)
– Plant reportedly designed for tsunami about 6 meters. Actual tsunami is approx twice that
– Flooding of diesel generators causes them to fail, resulting in station blackout
– Only batteries are still available
– Failure of emergency core cooling systems
Timeline of Events
(continued)
How Are We Different?
After the Accident
Unit 1
Unit 3
Unit 4
Unit 2
• Very large earthquakes occur at adjacent tectonic plates. We aren’t near one.
• There are no active or capable faults within the vicinity of the site which are capable of producing large earthquakes.
• Our site is 435 feet above sea level and more than 100 miles from the ocean.
Our Site Is Much Less
Likely to Have an
Earthquake or Tsunami

Making Headway
on Right-of-Way• Keeping power lines clear of trees and
branches has resulted in an 89 percent
improvement in reliability (in vegetation-
related outages) in the past year.
• Based on ANSI A300, SCE&G’s tree-
trimming program directs future tree
growth away from power lines by
trimming only limbs that are growing
toward the wire.
• “I remember during a small storm in
December 2004, we were here for 24 to
48 hours straight, and it was half the size
of the January event. Trimming has made
a huge difference in customer reliability.”

Rules
What’s the Big Deal?
• The North American Electric Reliability
Corporation (NERC) is an international
regulatory authority established to evaluate
reliability of the bulk power system in North
America.
• October 2010 NERC Study identified 4
potential EPA rules that could result in unit
retirements or forced retrofits between 2013
and 2018.
What’s the Big Deal?
• The rules have been in development for
years and are currently undergoing court-
ordered revisions that must be implemented
within mandatory timeframes.
• NERC predicts that these 4 rules will have a
significant potential impact to reliability should
they be implemented as proposed.
Four Important Emerging
Regulations
1. Clean Air Transport Rule – CATR
2. Mercury and Air Toxics Std. – MACT
3. Thermal Power Plant Cooling Water
Intake Structures Rule - 316(b)
4. Coal Combustion Residuals - CCR
Air Regulations
Clean Air Transport Rule - CATR
• Developed under the Clean Air Act
• Proposed in August 2010
• Final Rule due by June 2011
• Prohibits pollution of downwind states
Air Regulations
• Replaces the Clean Air Interstate Rule that
was remanded in 2008 (Greater emission
reductions)
• Seeks emission reductions of sulfur
dioxide (SO2) and nitrogen oxides (NOx)
–Greatest impact on coal-fired generation
• Will result in shift from coal to other fuel
sources with less SO2 and NOx emissions

Mercury and Air
Toxics Standard
• Developed under the Clean Air
Act
• Proposed March 16, 2011
• Final Rule due by November 16,
2011
• Up to 4 year compliance timeline
• Directly affects coal and oil fired
electric generating units (approx.
1350 units nationwide)
Mercury and Air
Toxics Standard
• Seeks emission reductions of mercury and
air toxics (metals, acid gases and organics)
• Requires Maximum Achievable Control
Technology (MACT)
– Wet or dry scrubbers
– Dry sorbent injection
– Activated carbon injection systems
– Baghouses
Mercury and Air
Toxics Standard
• Industry-wide costs estimated at
$10.9 billion annually
• Significant burden on small power
producers
• Older plants most affected
–Older technology
–Fewer air pollution controls
–Operate less

• Public hearings and comment period
Coal Combustion
Residuals Rule
• Rule to be finalized late 2012
• Coal combustion residuals (CCRs)
– flyash, boiler slag, bottom ash and
gypsum from scrubbers
• CCRs will be either:
– Regulated as a listed waste (hazardous
waste) under Subtitle C, or
– Regulated as non-hazardous waste
under Subtitle D
Coal Combustion
Residuals Rule
• Hazardous waste regulation will be expensive
– Capital cost of equipment retrofit
– Annual cost of material management
• No hazardous waste landfills in SC (AL is the closest)
• Insufficient capacity in existing hazardous waste landfills

Electric Metering
• Metering is often referred as the “cash register”.
• Mechanism that is used to measure energy flow across the grid.
• Provides the information necessary to bill energy usage and monitor load.
• Metering is truly cross-functional, because it must work in conjunction with the applicable electrical systems, while also meeting the requirements of the rate structure, accounting systems, and meter reading systems.
Metering – Entire
Spectrum
Self-Contained
Metering
• All current passes directly through the meter• Constant = 1• All measurement is handled directly within the
meter• Small/Medium services
2 Stylesa) Socket style (0 – 200 amps)b) Bolt-In style (201 – 600 amps)
Transformer-Rated
Metering
• Used on services either > 600 amps or
> 480 volts
• Requires Current Transformers (CTs)
• May require Potential Transformers
(PTs)
• Constant > 1
Current
Transformers (CTs)
•Reduces current to a level that’s practical for a meter to handle.
•Reduces current that’s directed to the meter by a known ratio
•Typically expressed in terms of primary rating to 5 amps
•Voltage class typically determines the size of a CT
•Wide range of ratios available
•CTs are a component of the measurement system
•CT selection is very important to ensure overall accuracy
Potential
Transformers (PTs)•Reduces voltage to a level that’s practical and safe for a meter to handle
•Reduces voltage that’s directed to the meter by a known ratio
•Typically expressed in terms of primary rating to 1 volts
•Voltage class typically determines the size of a PT
•Wide range of ratios available
•PTs must be matched to the service voltage
