With decades of experience building, operating and continually optimizing our portfolio of over 11 GW of coal-fired assets in Europe and Russia, we understand the challenges of maximizing the return on investment from coal-fired plant

Over the past two decades we have built coal-fired plants in the Netherlands, Germany and Russia, converted several European plants to full or partial biomass firing, and managed the upgrade of coal-fired assets internationally.

We understand the market opportunities for flexibly operating plants originally designed for base load operation. Our expertise has supported flexibility programs for over 25 years , enabling our own coal-fired assets to achieve optimized start-up regimes, greater flexibility and reduced load operation.

Our clients benefit from our expertise in plant life extension, with our specialists responsible for major refurbishments that have ensured the extended safe operation of plants between 20 and 25 years on their original design life.

Your benefits

Our services will support you to:

  • Reduce operational and capital expenditure
  • Optimize maintenance and outage strategy
  • Improve performance
  • Stay compliant
  • Extend plant life

Through-life Services

Fuel costs reduced

Our client entrusted us to improve the fuel flexibility of a high order merit fleet. We assessed the technical configuration, including the increased damage potential and following our recommendations, several technical parameters were adapted. These made it possible to increase the use of lower-cost coal with heterogeneous coal quality. With our support the improved fuel selection reduced coal costs across the fleet by approximately €10m per year.

Feasibility, Construction, Commissioning

Building new coal-fired plants

We have provided turnkey services for new 1,100 MW hard coal-fired plants across Europe and an 800 MW lignite-fired plant in Russia. All were designed with supercritical steam parameters to achieve state-of-the-art, high plant efficiency values. Our client focused on their core business while we used proven skills and experience to take care of project governance, project management, engineering, procurement, and site and commissioning management.

Operation & Maintenance

Loss of generation avoided

Our client contacted us following a routine inspection at an advanced super-critical power plant, where defects were identified in reheater 2 welds. Our root cause analysis identified relaxation cracking and stress corrosion cracking. We were able to propose a safety case, including exclusion zones, to enable operation while longer term solutions were developed. Two months’ lost generation at the highest generation prices was avoided.

Asset Management & Optimization

Flexible operation

For more than two decades we have supported a number of coal-fired power plants built in the 1960’s to enable flexible operation. We developed start-up techniques which both reduced plant damage and start-up time, together with associated fuel cost. This work was underpinned by our Integrity Assessment expertise. We also developed design upgrades to mitigate the effects of two shift operation. We continue to support these plants, one of which has a lead unit that has operated for more than 310,000 hours and carried out 2,200
starts.

Decommissioning

Innovative solution for managing end of life

We are sharing our expertise to support a UK generator‘s decommissioning strategy for their large coal-fired asset. Our feasibility studies into the disentanglement of various systems will allow for resale opportunities and the long-term preservation of boiler components for future developments. This is part of the ongoing work we are doing with our client to provide innovative solutions in the decommissioning and demolition phases in order to maximize any potential value opportunities.
