Optimized generation schedule
planning to improve flexibility
for minimum fuel cost
Energy Management Suite
Instrumentation, Controls & Electrical
Energy Management Suite SPPA-M3000
Generation Planning and Monitoring
optimizes asset utilization for the entire power
plant fleet by real-time integration of financial
and generation information. As part of the
SPPA-M3000 Energy Management Suite, it
consists of the modules "Availability, Load
Capability and Events", "Economic Dispatch"
and "Load Scheduling and Generation
Monitoring".
Your Benefits
■ Reduced fuel costs due to
minimized excess
production
■ Maximum efficiency as the
result of power production
by the most cost-efficient
plants
■ Increased sales volume as
available capacity is placed
on the market
The Task
Growing environmental awareness mandates
increasing utilization of renewables. Since
energy from renewable sources is granted
feed-in priority, this demands greater flexibility and adaptability to short-term changes
in demand of most fossil-fuel power plants.
The increasing requirement for higher flexibility
results in use of base-load plants as peakers
or these being made available for the reserve
energy market. In addition, rising fuel costs
and fierce competition trigger the need to
focus on costs.
The challenge is to cope with flexibility requirements and to define the optimum dispatch
strategy simultaneously. Since important
factors like maintenance needs, fuel costs,
emissions credits, market prices and sales
volume interact with each other and are
documented and managed within different
systems, the task becomes highly complex.
financial data from the ERP system. Independently of the source of information, it provides
comprehensive data on a uniform user interface: role-based and in near real time. To gather all relevant information and determine the
optimum cost situation, Generation Planning
and Monitoring draws on a set of linear equations with n variables, taking into account
environmental constraints. Unlike an Excelbased program, Generation Planning and
Monitoring reacts immediately to changes
and provides recommendations for the
dispatcher every two minutes.
This way, it is immediately clear when additional capacity can be sold on the market to reap
the benefit of high prices.
Generation Monitoring allows problems to be
identified at the fleet level, quick reaction to
a request from the grid operator by giving the
right fleet overview information on a single,
cumulative production level and by linking
current production directly with economic
dispatch.
SPPA-M3000 Generation Planning and Monitoring bridges the
gap between high flexibility and minimum costs
Our Solution
SPPA-M3000 Generation Planning and Monitoring solves these problems as it integrates real
time DCS data, maintenance information and

The Modules
Availability, Capability & Events
Economic Dispatch
Generation Scheduling & Monitoring
■ Event Logging (based on requirements of NERC, IEEE 762, VGB, etc.)
for current and future events
■ Restrictions on future production
existing due to maintenance work
already scheduled (interval- or
condition-based maintenance)
or faults requiring maintenance (e.g.
forced outage) of main components
■ Based on the prioritization and
impact of these events, management are shown the impact of
these on planned production
■ Visualization of the possible plant/
fleet capability for the requested
future time period, based on the
plant component tree
■ Short- and mid-term generation
planning for thermal and hydro
plants and their components
■ Direct linkage to ERP System allows
event reporting to a higher quality
level and saves time
Provides operations planning based
on current changes and use of the
individual plants and simultaneously
indicates how demands on production
volume and flexibility are to be met at
minimum cost.
■ Consideration of load capabilities
processed by the module Availability,
Capability & Events
■ Consideration of operating costs
from the ERP system
■ Consideration of remaining capacity,
fuel stocks, efficiency curves and
startup
■ Consideration of contract situation,
e. g. regarding gas supply
■ Send/receive and accept new
generation schedules
■ Monitor the current power plant
output at plant or fleet level
■ Display of schedule deviations,
reduced capacities due to problems
in the remainder of the schedule
period
■ Communications board: Online
communication with other plants
and overview of alarms or reports
on current fuel consumption
■ Summarized production overview.
In case of deviations, direct link
to economic dispatch to react
on missing generation capacity
