Marksan Global offers enterprise software, integrating project and asset management, service management – including customer engagement tools - with core ERP functionality to the power transmission and distribution industry. We provide customers with state-of-the-art technology combined with power transmission and distribution know-how under the concept of localization through customer orientation. Turnkey engineering and project management are centers of our competence among our broad range of medium and high voltage products for the electrical industry.

Mobile Substation

The prefabricated high (HV) and medium voltage (MV) mobile substation can replace the conventional electrical substation. It is a perfect solution to produce one or more transportable line or transformation bays, as all parts are mounted on semi-trailers or skids. The mobile substation is a plug and play solution, which allows to reduce installation times on the construction site. It can be used as a back-up plant in the event of an emergency, serving as a temporal solution or for extraordinary maintenance of an existing electrical substation.

When it comes to providing reliable electric service to more than 10,000 meters across three parishes, substations are critical components in the process. When a substation transformer fails, power could be lost to literally thousands of homes and businesses.

Smart Grid

A smart grid is an electrical grid which includes a variety of operation and energy measures including smart meters, smart appliances, renewable energy resources, and energy efficient resources.

Electronic power conditioning and control of the production and distribution of electricity are important aspects of the smart grid.

High-Mid-Low Voltage Substations

High-Mid-Low Voltage substations, the node points of today’s complex power transmission infrastructure, play a key role in meeting this demand safely and reliably. Siemens supplies them on a turnkey basis. Wherever you are, Marksan Global is your reliable partner for the one-stop planning and construction of customized, state-of-the-art high-voltage substations.

High-Mid-Low Voltage Products

For power grid operators and utility companies the reliability of their power transmission and distribution equipment installed in their network is vital. Investments in grid renewal and extensions are costly; equipment needs to last for decades. On top of that, it is important to eliminate electrical failures, reduce power outages, and increase the safety of people who work in critical environments.

Marksan Global makes sure that manufacturers comply with international standards, national deviations and end-user specifications to maintain a high level of safety and reliability. We offer you the complete scope of low, medium and high voltage testing for power transmission & distribution equipment. Our services are applicable to equipment manufacturers, energy utility companies, grid operators and large-scale energy users, amongst others.

HV Direct Current Transmission Systems (HVDC)

High Voltage Direct Current (HVDC) technology is commonly used as a method to isolate two independent Alternating Current (AC) power grids while permitting the exchange of power between both AC grids. HVDC technology can disconnect and isolate each AC grid from the other in the event of a blackout of one of the AC grids to avoid losing both AC grids. This isolation technique is commonly used at the interconnection points of AC grids for two countries.

Flexible AC Transmission System (FACTS):

Marksan Global provides solutions that offer grid operators the ability to provide reactive power support, enhance controllability, improve stability and increase power transfer capability of AC transmission systems. Our portfolio includes power electronic based technology as well as more traditional electro-mechanical solutions, which utility operators have become more interested in because of their grid friendly and reliable nature.

Grid Access Solutions

The demand on electricity grids is greater than ever before – driven by developments on both the generations and consumption sides. And income can only flow where the electricity from your offshore wind farm flows reliably too. We take care of both on your behalf, as we combine. Because we combine innovative technologies with proven solutions for grid connection, successfully tested in thousands of applications. It doesn’t matter whether you need turnkey solutions, all-inclusive component and system packages or service and maintenance: we help your offshore wind farm to deliver, no matter how hard the wind blows.

Gas Insulated Transmission Lines (GIL)

Gas-insulated transmission lines (GIL) are the safe and flexible alternative to overhead lines and take up much less space while providing the same power transmission. Since they hardly impact on the landscape, and their minimal electromagnetic radiation means they can also be used close to, or even within buildings, GIL can be considered for a wide range of applications. They are suitable for providing a continuation for overhead lines underground, connecting power stations to the power network, or as a space-saving way to connect major industrial plants to the public grid.

Gas-insulated transmission lines (GIL) have already proven their technical reliability for a number of decades, since they offer outstanding safety in operation and even in the event of failure, in addition to their very good transmission performance. Any impact on individuals or neighboring resources can be largely ruled out. Electrical losses are kept comparatively low due to the large conductor cross section of the GIL system.

Gas Based Power Plant

MARKSAN provides renowned Brands Gas Genset Power Plant. Our principles’ gas power plants use natural gas, the cleanest fossil fuel available, in the most economical way. This is possible thanks to their high efficiency at any load and unbeatable flexibility to start and stop exactly according to needs.

Besides the combination of efficiency and flexibility, these gas power plants also offer low emissions, and can provide a great amount of power in a reduced site, making it the optimal solution for locations where minimizing the environmental impact is a priority. As such, they can be placed close to consumption nodes, optimizing the power system.

MARKSAN gas power plants can run on natural gas, LPG and various biogases

Working Principle:

  • The gas turbine compresses air and mixes it with fuel that is heated to a very high temperature. The hot air-fuel mixture moves through the gas turbine blades.
  • The fast-spinning turbine drives a generator that converts a portion of the spinning energy into electricity.
