History
J. Mitchell Energy Corporation was built in 1995
as a peaking energy station serving nearby areas
as well as merchant contract energy. As
communities and businesses grow andtechnology advances the need for reliable energy
has also grown. In 1992 J. Mitchell Energy
Corporation entered into a 10 year contract with
North Carolina based energy giant, PrevattePower. The contract included an agreement that
allowed J. Mitchell Energy Corporation to use
Prevatte Powers transmission lines in return for
premium rates and service priority. Located in

Mission Statement &
ObjectivesMission: J.Mitchell Energy Corporationsgoal is to provide safe and reliable power.
We are committed to servicing the
community and the safest and most cost-efficient manner possible. We will act with
integrity, be responsible environmental
and financial stewards and continue to
adapt and improve.
Objectives:
Increase plant size by adding two combinedcycle units and one steam turbine.
Continue to build environmentally friendly and
cost effective natural gas power plants to
support the communities growing needs.

Concept Generation
The idea for an independent peaking stationcame from the rapid growth of the population as
well as the downfall of merchant plants in the late
1990s. The eventual downfall of Enron left many
power giants struggling to manage assets theyhad built as a new jerk reaction to the expansion
of the merchant market. The demise of Enron
left many power companies with power plants
and no contracts to run them. The conceptbehind this power plant came from the increasing
need to be able to start power plants quickly and
reliably but without the initial capital to build and
maintain a power plant. Therefore, this peaking

Product Concept
While electricity has always been around in
some form or another, Benjamin Franklin
proved lightening was electrical in naturearound 1752. His experiments along with
the work of many others has made electricity
a commodity that none of us can live without.
The challenge in present times is providingreliable electricity at the lowest possible cost
customers. Electric power can be generated
many ways. J.Mitchell uses natural gas and
General Electric combustion turbines to

Process Selection CriteriaJ. Mitchell Energy Corporation uses a
just-in-time production method to
manufacture electricity and send it to the
grid. Due to contractual agreements andobligations, as well as not being able to
store energy we do not run until we are
needed. This process was selected
based on: The terms and conditions of a contract
The availabilty of multi-crafted
technicians
The inability to store energy (no WIP or

Since the plant is contracted, it only operates when called up to do so. It takes a lot
of planning and maintenance to be ready when the call comes. Daily maintenance
assignments are performed as well as hourly inspection rounds. The start up
process can take up to an hourbefore the gas turbines can be started. Technicians
have several steps to ensure the balance of plant equipment is ready (opening
valves, verifying automated equipment response, etc) before the start button is
pressed.

maintenance/scheduling
Many of the bottlenecks in a power plant are shifting in nature. If maintenance
is performed or parts or not ordered, the plant potentially cannot operate.
Incorrect information collected and input into the system can delay or stop
units from performing. Malfunctioning instrumentation may fail to alert control
room operators to failing pumps, high levels in boilers, or valves in incorrect
position. These conditions can be costly and catastrophic. They can also
lead to a false start or a unit trip thus reducing the plants reliablity.

The Plant Manager is the person responsible for
overall quality control. The Operations & Results
Superintendent is responsible for identify items that
need maintenance and working it into the production
schedule. The Maintenance Superintendent is
responsible for ensure maintenance is performed.The Superintendents report to the Plant Manager.
The technicians are responsible for reportingmachine problems and other potential bottlenecks.
They also report the job status to the
Superintendents. The Materials Supervisor guides
Storekeepers and monitors purchasing and
inventory. The Materials Supervisor reports to the
Maintenance Superintendent.

Facilitization
Power generated at the
power plant is transferred tothe switchyard and
transmitted to homes and
businesses.
