ECO|RAMChanging market requirements like deregulation have generated a high cost pressure on power producers. Tomaintain competitiveness, it is necessary to find new measures to reduce costs and increase revenues, which can be

realised at the actual market conditions. ECO|RAM has been created to identify tangible improvement measures by

systematically analyzing the power plant. This results in a portfolio of improvement measures regarding plant

equipment, operation and maintenance.

MethodologyDuring the development of

ECO|RAM, technical material

regarding the design, theoperation and maintenance of a

plant have been prepared.

Comprehensive technical and

operational benchmark data as

well as a catalogue of potential

improvement measures support

the systematic analysis of plants.

For that purpose, key-data and

properties have been compiled in

the assessment documents.Linking the detailed cost structure

of a power plant to component

specific features of design,

operation and maintenance has

been another prerequisite for

establishing the methodology.

ProcessBefore the start of an ECO|RAM

project, the project goals and

criteria for financial evaluation aredefined by the customer

i.e. the desired payback period, the

parameters for financial evaluation

or the interest/discount rate. etc.

The project is carried out in close

cooperation with the customer in

a joint team. This makes sure that

all relevant boundary conditions of

the power plant and its operation

are considered and that thefeasibility of the proposed

improvement measures is secured.

The process is divided in two

phases: In Phase 1 the actual

status and performance of the

plant is determined by a site

assessment. New improvement

ideas are generated, which are

reviewed, grouped & selected as

Potentials.

Each Potential is investigated to

determine technical feasibility and

expected benefit. Based on the

results of Phase 1 the customer

decides which potentials shall be

further elaborated in the second

phase. Phase 1 is typically

executed within 8 to 10 weeks

In Phase 2, each selected potential

is analyzed in greater detail. A

comprehensive technical review is

undertaken. Costs and benefits -

including initial investment,

ongoing operating costs, projectedpayback and technical benefits

are quantified. In this way an

implementation/investment

decision can be prepared.

The time frame of Phase 2

strongly depends on the findings

of Phase 1, considering the

number and complexity of the

Potentials, and takes 16 to 20

weeks

Typical ResultsTypical potentials generated

include:

Modification of

components/systems

Optimisation of operation

modes

Alterations to maintenance

strategies.

Expected benefits are:

Improvement of availability

Increase of efficiency

Increase of capacity

Reduction of auxiliary power

consumptionn

Greater operational flexibility. Greater operational flexibility.

The improvement measures are

summarized and ranked based on

the specific boundary conditions

set by the customer e.g. budget,

outage schedule, and payback

period etc.

Of these projects, 8 have been

carried out to the conclusion of

Phase 2, each providing

demonstrable benefits for the

realized with minor investment

costs.

Overall, more than 450

improvement ideas have been

identified, of which more than 150

Potentials were both technically

and economically viable according

to the customers specific criteria

and were carried through to Phase

2 for detailed analysis.
