Trust us to help you achieve reliability and compliance

Uniper has extensive experience in delivering engineering and technical services for energy recovery projects across Europe.

Our long history as an owner and operator of waste and biomass generation assets gives us a deep understanding of the key challenges facing energy recovery plant operators - maintaining availability and reliability, and achieving environmental compliance. You will benefit from the skills and solutions we have developed to successfully address issues such as component degradation and environmental emissions in our own plants.

We offer alternative solutions that are focused on your priorities, helping you to reduce costs and increase your independence from original equipment manufacturers.

Your benefits

Our services will support you to:

  • Improve reliability
  • Stay compliant
  • Optimize performance
  • Optimize outage strategy
  • Reduce capital expenditure

 

Through-life Services

Supporting claim against OEM

Our client was concerned that performance of the air-cooled condenser of their recently commissioned waste-to-energy plant was below design values, potentially reducing maximum power output during the summer period. Our specialist tests determined that the air flow to the ACC was almost 60% below the design value, making a significant impact on steam turbine power output during periods of high ambient temperature. Further measurements confirmed the ACC was not operating at design conditions. Our client was able to use the data in claims against the OEM to provide a ‘fit for purpose’ plant.

Feasibility, Construction, Commissioning

Managing delivery of new plants

Our client chose us to take care of the development of several new waste to energy sites in Germany with a combined capacity of 800,000 t/a. We managed the engineering, QA/QC, construction, site and commissioning supervision and claim management to ensure our client’s
projects were delivered on time and within budget.

Operation & Maintenance

Emissions abatement optimized

Our client’s plant was operating close to environmental permit limits despite high levels of ammonia injection. We investigated the selective non-catalytic reduction system used for NOx abatement on the plant’s fluidized bed combustor. We used real time test data to optimize the injection lance configurations. This enabled our client to achieve lower NOx emissions and reduce their operational costs.

Asset Management & Optimization

C&I system renewed

A client in the Netherlands chose us to renew the control and instrumentation system in their waste to energy plant producing 700,000 t of process steam and 105,000 MWh electricity. We led the process engineering, project management and programming, and hardware engineering as well as the commissioning and the successful trial runs of the new system. As a result, we have achieved cost savings and operational efficiencies by delivering a state-of-the-art C&I system which is a central part of life extension measures for the plant.

Decommissioning

Relocation of turbine and generator island

A German client asked us to relocate the turbine, gearbox, generator and oil system of a 34 MWel 90 MWth waste to energy plant to a new location. We decommissioned and dismantled the turbine in its original location, inspected and refurbished all components and installed the turbine on new foundations in the new location. As a result, the turbine and generator island were not only relocated to another plant, we could also increase the process steam pressure and equipped the system with a new control and instrumentation system.
