- Examples
Given the relatively low fuel cost of coal- and nuclear-powered steam turbine generators, and the increasing strategic value of existing sites, a modernization of existing equipment can be more cost-effective and faster than installing new generation equipment. Performance Enhancement Programs can help you to improve assets and environmental compatibility, and furthermore lead to higher reliability and overall performance. Our customers are impressed by the performance enhancements resulting from modernizations. We prepare either your power plant, your plant in the oil & gas sector or your industrial plant for tomorrow and beyond. We inspect your plant, whether Siemens plants or plants manufactured by other OEMs, and give you the options tailored to your needs.
Focused on the turbine generator and its auxiliaries, Siemens provides the interface across various disciplines to address the boiler (or steam generator), the control system and the balance of plant considerations on any modernization activity. We also assist in evaluating the net present value calculation and IRR analyses necessary to justify the project. In addition, uniquely qualified engineers provide complete turnkey installation of modernized equipment in concert with the plant's inspection requirements and scheduled outage duration. They can help to plan the outage work in detail with other subcontractors to ensure an on-time completion. Finally, Siemens has the capability to utilize creative financing for the modernization capital, based on sales of the incremental megawatts.
Your benefits may include:
- Improved performance in terms of availability, reliability, efficiency and flexibility
- Reduced maintenance costs by extended maintenance intervals and shorter outages
- Lifetime extension
- Improved emissions to meet environmental requirements
- Adoption to changed power/process requirements.
