Consultancy Services for power plants

Changing business conditions and ageing of the plant may lead to your plant no longer optimally matching the current market demands.

An increased profitability and competitiveness can be achieved through a holistic plant solution assessment focusing on:

• Operational Flexibility - Assess typical plant operation for enhanced flexibility, start up and shut down, low load operating capability and expanded operating ranges
• Thermal Performance Recovery - Evaluation of current plant performance against modeled design conditions and provide recommendations to address any gaps
• Availability and Reliability Improvement - Review of historic data/records to determine factors tied to availability & reliability
• Plant Upgrade Capability - Evaluation of equipment limitations and identification of solutions to help maximize plant upgrade potential

Backed by extensive engineering and O&M experience, Siemens Energy experts conduct an in-depth plant and process analysis in 3 key phases:

• Identify and define objectives: Together with customers we develop the operational goals, based on your value drivers and specific site conditions.
• Technical Evaluation and Engineering Analysis: Remote data collection and site visit through Siemens Energy subject matter specialists. Analysis of plant baseline condition, Fleet Benchmarking and Assessment of Risks and Opportunities.
• Tailored Solution: Comprehensive final report with optimization recommendations, based on the asset condition and potential for improvements.

Energy System Design offers a tailormade model for CO₂ emission reduction and Total Expenditures (TOTEX) optimization for site specific boundary conditions.

The ESD model, using data-based simulation scenarios, can enable you to

• identify the optimal asset combination regarding an optimal ecologic and economic solution
• utilize unique OEM pricing knowledge and performance information
• select optimal technology and integrate it into existing assets
• generate and implement a stepwise and agile implementation roadmap
• identify future revenue streams

ESD is designed to deliver a comprehensive overview of possible technologies and asset combinations to help you meet your CO₂ emission and TOTEX targets in the following steps:

• Scoping of ESD Study:
  Joint definition of reference scenario, pre-selection of potential sensitivity analyses and development of overall timeline.
• Data collection and review:
  Collection of existing configuration, price and performance indication of assets and market data.
• Model set-up:
  ESD model for reference year and scenarios. Plausibility check of model.
• Scenario evaluation and sensitivity analysis:
  Run ESD software model to derive an optimal technology and asset configuration of the defined ESD. Assess sensitivity of results with respect to key assumptions.
• Recommendations on optimal technology selection
• Optional: consultative support for potential application for available funding (e.g. subsidies)
   

Outlook: budgetary estimate for respective hardware / solution to implement the assessed decarbonization strategy.

The Coal to Gas Repowering Feasibility Assessment is an initial step that can show you a pathway, leading to a replacement of a coal fired power plant with a highly efficient gas turbine power plant, reducing CO₂ emissions significantly.

To make a more informed decision about a potential repowering project, this investigation looks at the crucial terminal points and detects possible impediments from the beginning.

To significantly reduce CO₂ emissions a repowering of a coal fired power plant is an appropriate way.

Further investigate your repowering potential with the FEED study! This detailed investigation is the basis for secure planning which can enable you to make informed decisions.

Through dedicated consulting activities and specialist input, Siemens Energy provides you its latest expertise on Coal to Gas Repowering based on our extensive O&M and OEM experience.

The investigations, modelling and calculations of the FEED serve as a basis for

• Details on new equipment to be supplied and selection of the works to be performed
• Elaboration and specification of the necessary modifications to the equipment remaining in the plant
• Calculation of potential performance data
• Determination of all services to be performed and the scope of hardware assembly
• Clarification of any other scopes of services and deliverables associated with the repowering project

Through dedicated consulting activities and specialist input, Siemens Energy can provide you the benefit of its latest expertise on Coal to Gas repowering based on our extensive O&M and OEM experience.

The Coal to Gas Feasibility Assessment includes

• Detailed site walk down and data / document acquisition
• 3D Scan
• Detailed evaluation of all project relevant terminal points of
• Soil / Environment
• Layout / Space
• Gas Supply
• High Voltage Connection
• Cooling Water Supply
  

The next step could be to conduct the more detailed FEED Study or to receive a budgetary offer

The Front End Engineering Design (FEED) contains the result of detailed investigations with regard to the integration of the power block and its ancillary plants on the basis of the findings of the site assessment, the study of the plant documentation, the plant-specific parameters, and the operating parameters stored in the I&C system.

The Coal to Gas FEED typically includes

• Civil, mechanical and thermodynamic engineering
• HAZOP, safety study
• 3D preliminary models
• Equipment layout and installation plan
• Engineering design package development
• P&ID, piping, instrumentation diagram
• Repowering Project timeline
• Fixed-bid quote or final report as needed

Grid stability is becoming the focus point of many grid operators as energy systems become increasingly decarbonized through implementation of expanding renewable energy technologies.

Our Feasibility Assessment is designed to provide an adequate base to help you make an informed decision on how to repurpose or multi-purpose existing assets by offering grid stability services.

You may be able to gain additional revenue streams by helping maintain a stable and resilient grid.

Grid stability being the focus point of the grid operator due to the energy system is decarbonized through expanding renewable energy technologies.

Following an initial Feasibility Assessment, this FEED study identifies and mitigates project risks, delivering clear technical and financial details to make an informed decision for a major capital investment.

You can gain additional revenue streams by converting your existing assets ensuring stable and resilient grid.

The Rotating Grid Stabilizer Feasibility Assessment typically includes:

• Identification of feasible design options through a joint collaboration with customer and Siemens Energy’s lead consultant and subject matter specialist
• Concept development for tailored design options with a clear technical recommendation and financial estimate for each option
• Optional: A dynamic grid simulation study
  

Next Steps: After the Feasibility Assessment you can choose your appropriate solution and proceed with the more detailed Front End Engineering Design FEED, that provides specific steps to implement the solution. This Feasibility Assessment is typically the precondition for a budgetary estimate of the respective solution.

The Rotating Grid Stabilizer FEED delivers the required scope of the complex project by complete engineering up to point of planning long-lead equipment. The final report and presentation with a detailed concept includes for example

• Modifications required for conversion
• On site 3D Scan and new configuration layout
