ASSET MANAGEMENT
to make existing power plants greener
and lower their emissions rarely meet
with public resistance.
The prospect of preserving existing
jobs or even creating new ones and
strengthening
the
region's
economy
is usually supported by the local community.
Another factor that shouldn't
be underestimated is that trained and
experienced power plant personnel can
continue to work, and in contrast to
greenfield projects, there's no need to
start from scratch with the recruitment
of skilled personnel. At the R.D. Morrow,
Sr. Generating Station, for example, the
operator decided to keep all of the plant's
employees on throughout the project to
help with demolition, construction, and
conversion work, which had a positive
impact on the local economy and resulted
in overall savings.
One way to breathe new life into an
existing plant is an engine exchange
project. The complete replacement of
a gas turbine with a higher efficiency
machine that can burn hydrogen as a
fuel can be performed in just a few
months. In a very short time, an old
power plant can be transformed into
a state-of-the-art plant that has all the
features required by current and future
energy systems.
compensation, and therefore, generates
additional revenue. Operators who
can react quickly to fluctuating electricIf
an existing power plant site is
repurposed, cost pools for land,
development, foundations, and grid
connection are reduced or eliminated.
More Economical Operation Thanks
to Significantly Higher Flexibility
With the steady expansion of renewable
energies in many countries, operational
flexibility in conventional power plants
is playing an increasingly important role.
Because wind and solar power plants
can't
produce electricity
continuously
and in line with demand, gas-fired power
plants in particular must be able to respond
as quickly as possible and ramp
up or ramp down production.
In most electricity markets, the mere
promise of being able to either feed in
power or curtail production at short notice
is rewarded with corresponding
ity prices on the spot market can also
increase their sales accordingly. Electricity
producers who have combined
fleets that include wind and solar power
plants can make supply commitments
that wouldn't otherwise be possible by
increasing the operational flexibility of
their conventional power plants.
Repowering
steam
power
plants
with highly efficient and flexible gas
turbines increases operational flexibility
from 20% to 100% plant capacity,
which creates completely new opportunities
for operators. BEX projects are
also providing higher operational flexibility
by allowing part-load capability
and fast ramp rates.
