“VERY BIG OUTAGE“

inside the Darlington vacuum building.
Electricity generation in Q1 2009 was 25.6 TWh, 13 per cent lower than Q1 2008
generation of 29.4 TWh. OPG reported a net loss of $9 million for the three
months ended March 31, 2009, compared to net income of $162 million for the
same period in 2008.
A decrease in nuclear production was primarily a result of planned
maintenance outages. Hydroelectric production was marginally lower in Q1 2009
than for the same period in 2008. A 2.7 TWh decrease in fossil-fuelled production
was primarily due to lower electricity demand in Ontario’s contracting
economy, an increase in electricity production from other Ontario generators,
and a significant reduction in natural gas prices resulting in a displacement of
coal-fired production.
Earnings in the first quarter were unfavourably affected by a decrease in gross
margin of $39 million compared to the same period in 2008. The decrease in
gross margin was primarily due to lower fossil-fuelled and nuclear generation,
and higher fossil fuel prices. The impact of lower fossil generation was partially
offset by the Ontario Electricity Financial Corporation
contingency support agreement to recover the cost of
lower production at Lambton and Nanticoke.
Higher operations, maintenance and administration
expenses were mainly a result of increased planned
outage and maintenance activities at the nuclear
stations. Losses from the Nuclear Funds
increased by $85 million primarily as a
result of a reduction in the Ontario
Consumer Price Index, which affected
the guaranteed return on the Used
Fuel Fund.

AN OPG-WIDE
EFFORT
Darlington's material condition is
in good shape.
May 25 marked the official end of the VBO with
the synchronization of Unit 2 to the Ontario grid.
(Unit 3 is now in a 42-day planned outage.) This
complex and demanding project was the largest
undertaken this year by OPG’s nuclear business and
its completion reflects well on OPG’s ability to plan
and execute complex projects in a timely manner.
Testing of the vacuum building systems is done
regularly, but every 12 years it is depressurized to
allow for the inspection and maintenance of the
station’s vacuum building structure to ensure its
continued availability. Completing the outage safely
and in a timely manner is a tribute to sound planning,
effective coordination, and near flawless execution
on the part of OPG’s outage staff.
“Teamwork is our strength,” said CNO Wayne
Robbins. “Everyone took ownership and accountability
to support each other and were highly engaged,
looking ahead to prepare the work. When faced
with a challenge, employees worked together to bring
any issues to a successful resolution.” Robbins praised
the contributions of nuclear staff as well as that of
stations around the company that made up the
shortfall caused by the site-wide, multi-week outage.
Planning and preparation were keys to knowing what
maintenance work was needed, to getting the right
work ready, and to executing tasks safely and correctly
the first time. “We have improved the material condition
and nuclear safety of the station and are coming
out of the outage with our lowest backlog ever,” said
Dan Norrad, VBO manager. “This will ensure
strong operational reliability in the months ahead.”

Electrical Safety – Be Aware
Electrical safety should be a priority at work and at
home. No matter where you are, take the time to identify
and control hazards. Once you are aware of the risks, you
and your family can more effectively prevent fires and
electrical contacts at home.
Statistics show there is good reason to pay attention.
In Ontario, between 1998 and 2007, an average of three
to four people per year were fatally electrocuted at home,
and between 2,000 and 3,000 residential electrical fires
occurred each year, the majority resulting in property
loss.
Safety Tips During Home Repairs
n Label your breakers and fuses.
n Before working on electrical circuits, open breakers
or remove fuses and test the circuits to ensure they are
not live.
n Avoid overhead lines when working outdoors.
Make Your Home Electrically Safe
n Ensure ground fault circuit interrupters are installed
near sinks in bathrooms, kitchens and laundry
rooms, and in exterior outlets.
n Avoid overloading circuits, creating an electrical
“octopus,” and resting furniture on electrical cords.
n Prevent overheating and breakage by not wrapping
electrical cords too tightly.
n Replace cracked or frayed electrical cords.
n Have your home’s electrical system checked by a
licensed electrician. Flickering lights, tripped circuit
breakers or blown fuses may indicate possible
electrical problems.
n Don’t use extension cords as a permanent solution
to a lack of outlets.
n Make sure your electrical equipment has a CSA, ULC
or other recognized certification mark. Beware of
counterfeit marks: Grammatical errors and conflicting
information may indicate that it is a fake. If the price
looks too good to be true, it may not be certified.

Wayne Robbins, Senior Vice President Darlington
Nuclear, has been appointed OPG’s new Chief Nuclear
Officer. Effective June 1, 2009, Robbins replaces Tom
Mitchell, who will become OPG’s new President on
July 1.
As Darlington Nuclear’s leader, Robbins directed the
station in 2008 to its highest level of overall station
performance in OPG’s history. During his tenure,
Darlington received its highest industry rating from the
World Association of Nuclear Operators – also a
CANDU first.
Robbins joined OPG (then Ontario Hydro) in 1980 as
a commissioning engineer at Pickering B and has held a
variety of increasingly responsible positions at Pickering
B, Pickering A and Darlington, including shift
manager, outage and authorized duty manager, director
of maintenance and operations for both Pickering A
and Pickering B. Robbins joined the Darlington

President Darlington Nuclear, effective June 1, 2009.
A graduate of Queen’s University, Seedhouse joined
Ontario Hydro/OPG in 1981 as a junior engineer and
has held progressively responsible roles at all three
nuclear stations, including shift supervisor, maintenance
and operations manager at Pickering B, director
of operations and maintenance (DOM) and director of
engineering at Darlington.
In 2007, Seedhouse led a review of OPG’s support
function costs on behalf of the CEO. As the DOM his
weekly updates to staff established a professional,
sometimes challenging, but always supportive
camaraderie with the employees at Darlington.
NIAGARA TUNNEL
UPDATE
While delayed, the Niagara Tunnel project continues
to be an important infrastructure project
in Ontario, with respect to its long-term value as
an added source of clean, renewable hydroelectric
power.
At the end of March, the tunnel boring machine had
advanced to 3,794 metres, representing 37 per cent
of the tunnel project. Now operating on a revised
alignment to minimize the remainder of excavation in
the Queenston shale formation, OPG and the
contractor – Strabag – have negotiated the contract
with a revised target cost and schedule. This
contract includes incentives related to achieving the
target cost and schedule.
The original total budget for the Niagara Tunnel project
was set at $985 million, with a completion date
for June 2010. The revised contract – approved by the
OPG Board – is estimated at $1.6 billion, with a
scheduled completion date now set at December 2013.
“Looking to the future, we are continuing to work on
the Niagara Tunnel while discussing with Strabag
the best way to route the remaining two-thirds of the
project,” said OPG President and CEO Jim Hankinson.
“I can assure you that, when completed, the tunnel
will provide a clean and economical source of
energy.”

Is it the end of 25 Hz?
In April, Sir Adam Beck 1 was the last 25 Hz generator to be
decommissioned. The 25 Hz generators existed at Beck 1 and
Rankine generating stations to provide power for large
industrial customers who did not want to replace existing
equipment and motors.

Michael Mirsky from Energy
Markets recalls, “Most people are
too young to remember, but until
the 1950s, all power was 25 cycle
and my parents told me how lights
used to flicker. When the conversion
happened, Ontario Hydro
trucks went through residential
areas offering a free swap of
electric clocks (the old clock
motors wouldn’t work right on 60 Hz). People would bring old
clocks that hadn’t worked in years for a free exchange!”
Mirsky continues, “Since then, 25 Hz supply was limited to
industrial users with huge motors that ran on 25 Hz in
northern Ontario and Niagara. Those motors are now gone,
NANTICOKE GS Makes Right Connection
At a recent gala in Toronto, representatives from Nanticoke GS received the
provincial “Passport to Prosperity Merit Award.” The award, which recognizes
employers who have consistently provided secondary-school students with
outstanding learning opportunities, is a testament to Nanticoke’s cooperative
education program and speaks to the willingness and dedication of
staff to train the next generation of young workers.
Nanticoke GS offers a secondary school co-op program with classes held
right on site. “The program offers a great deal of value for both students and
staff at Nanticoke,” said Kevin Borges, Mechanical Technician at Nanticoke,
who has been a part of the program for the last two years. “The students get
real work experience with one of the top employers in Canada. In exchange,
we get high-quality work and valuable input from students who are hungry for
knowledge.” “Nanticoke Generating Station is an outstanding example of an
employer champion,” said nominator Susan McFarlane, Guidance Counselor
at Hagersville Secondary School.
CORRECTION:
and the remaining generators producing 25 Hz have had their
output converted to 60 Hz.”
Major players in the power industry favoured different cycles
depending on use, but 25 Hz was chosen as a compromise and
stayed the industry choice for
decades. Around the late 1940s, the
early 25 Hz Ontario Hydro generators
were standardized at 60 Hz –
a huge project, launched under the
leadership of Chairman Robert
Saunders. It was a shock to some,
who never thought 25 Hz would
become obsolete.
Although Northeast Plant Group
also produced 25 Hz at Lower
Sturgeon, Wawaitin, and Sandy Falls on the Upper Mattagami
River, they were taken off line for redevelopment and are
currently under construction.
So, while it isn’t shocking, it’s still the end of 25
Hz as we know it.

Q1 2009 PERFORMANCE
Ask Finance... What is the difference between EFOR and
@ EFOR-Peak? OPG reports fossil reliability using Equivalent Force
Outage Rate (EFOR). EFOR is the ratio of time a unit is forced out
of service by unplanned events (including any forced deratings),
compared to the amount of time it was available to operate. As a result of the new limit
on CO 2 emissions, the operating strategy for these stations has changed. Fossil stations
are now expected to be available primarily during the peak demand periods of January
and February, and July and August. To reflect this, EFOR targets during peak demand
periods have been reduced to achieve improved reliability. Peak Equivalent Forced
Outage Rate (EFOR-Peak) is the ratio of time a unit is forced out of service, compared
to the amount of time it was available to operate during peak demand periods.
