METKA is a leading international contractor of fully integrated turnkey power generation projects with a focus on engineering, procurement and construction (EPC).
METKA is experienced in gas turbine-based power generation, including combined cycle, co-generation and simple cycle technology, providing world-class solutions and optimal performance. The company also undertakes hydro and solar power generation projects, as well as the rehabilitation and upgrading of existing power plants.
Engineering, procurement and construction (EPC) in the power industry
METKA provides the complete range of EPC services for large-scale power generation projects, which are needed to successfully deliver turnkey projects to its customers.
Timely delivery of complex power generation projects requires a blend of qualified EPC solutions, coordinated by specialist project management resources, including:
- Engineering, from the initial plant concept to the full detailed design of the plant.
- Procurement, including all aspects of procuring and delivery of all equipment, materials and services required.
- Construction, from on-site erection, testing and commissioning, up to the completion of the warranty period. METKA assigns specialist supervisors for each stage.
Turnkey plants and combined cycle power plants
Combined cycle plants offer significant advantages such as relatively low environmental impact, high operational flexibility and shorter project implementation times.
METKA covers both single and multi-shaft configurations, as well as a wide range of gas turbine models, including both heavy duty industrial and aero-derivative types.
Single shaft configurations, with the gas turbine and steam turbine on the same axis and connected to a single generator, have an advantage in terms of the compact layout. On the other hand, multi-shaft configurations may have one or more gas turbine-generators, together with a single steam turbine-generator.
Experienced in numerous combined cycle projects, in a wide range of configurations and generating capacities, METKA has the expertise to provide fully integrated project solutions and reliable long-term plant operation to its clients.
Simple cycle gas turbine power plants
For peaking duty or fast-track project execution, gas turbine based simple cycle plants are an ideal solution. Both industrial and aero-derivative type gas turbines are widely applied, with the latest generation aero-derivative turbines offering efficiencies above 40%. Where appropriate, METKA designs simple cycle plants to facilitate future conversion to combined cycle.
METKA has successfully carried out several projects to provide fast-track simple cycle power generation, especially with aero-derivative type gas turbines.
Fast-track mobile gas turbine power plants
METKA specialises in gas turbine based power plants, including mobile units, which can provide reliable electricity on a fast-track basis anywhere in the world.
Flexible to meet customers' needs, mobile gas turbine power units typically have a unit size of 20 to 25MW, with complete plants being scalable up to several hundred MW. Our mobile power plants include highly efficient gas turbines together with all necessary electrical and mechanical balance of plant equipment.
METKA has developed a fast-track approach in its solutions. All packages are delivered pre-assembled and pre-commissioned, so that on-site installation is limited to minor interconnecting piping and cabling works. This particular solution requires little or no site preparation, and can provide power to the grid in only a few months.
METKA's recent experience in this area includes the engineering, procurement, installation and commissioning of 38 fully trailer mounted mobile gas turbine power plants installed at eight different sites in Algeria, as well as ten additional sets being currently installed in Ghana, executed in collaboration with General Electric.
Solar photovoltaic (PV) power plants
Through its subsidiary METKA EGN, the company is capable of meeting the requirements of the rapidly growing global solar PV market.
METKA EGN is a world-class EPC contractor for utility-scale solar PV projects, with a customer portfolio that includes some of the leading investors in the PV sector.
Project references include more than 350MW of medium and large-scale PV projects in several countries, such as the UK, Bulgaria, Greece, Romania and Turkey.
Co-generation and combined heat and power plants
Co-generation applications are typically more complex in operation than standard combined cycle plants due to the requirement to support multiple operating modes, such as large variations in process steam requirements, or changing seasonal heating demand.
Strong plant integration and thermal cycle design skills are essential to ensure the co-generation plant can reliably support all required operational needs.
METKA has successfully completed a major co-generation plant project for Aluminium in Greece, one of the largest co-generation plants of its kind in Europe. The plant produces electricity for the network and highly reliable steam supply to the adjacent alumina production plant.
Operations and maintenance services for the power generation industry
METKA offers a complete range of operations and maintenance services to power plant owners. Building on its technical and organisational expertise, in addition to the significant operational experience acquired on the Mytilineos Group power plants in Greece.
The company has experience in setting up full-scope operations and maintenance services to ensure safe and efficient operations, as well as effective management of both planned and unplanned maintenance activities.
As the overall EPC / operations and maintenance contractor for major power plant investments, METKA provides a seamless handover from construction to operations.
