Principle and operation

The hydroelectric power station is a installation that produces electricity using the force of water. This is called hydraulic energy. The hydroelectric power station is made up of 3 main parts: the dam, the power station and the transformer.

The hydraulic dam is the key element in the operation of a hydroelectric power station. It is he who will command and direct the water in order to create electricity. Settled at the level of a river or a natural watercourse, it can take several names. The dam may be "over the water," indicating that it is not holding water. It can be "locked", in this case the water supply results from the rising tides. And finally, when it retains water, it is called a "retention dam". The latter is the most competitive, as it offers the opportunity to produce large amounts of electricity. It is built in strategic places to constitute a reservoir. The water stored in this lake will be poured into penstocks and led to the hydroelectric plant.

The hydroelectric power station is settled below the dam. The force of the falling water will thus activate the turbine, which will then operate the alternator. The latter will then produce an alternating current which will be sent to the electric transformer of the hydroelectric power station. The power of the hydropower plant is fundamentally derived from the force of the water. Thus, run-of-river dams, relying on sea currents, will create less electrical power than retention dams.

The transformer is the last key element in making hydroelectricity. This will amplify the voltage of the current that the alternator creates. This electricity will then be carried by the high and very high voltage lines.

The water that has been brought to the turbine is discharged to the river or stream through the tailrace channel.

Micro hydroelectric power station: development of intelligent hydroelectric solutions


Energy, industrial and marine companies are studying intensively renewable, low carbon sources of energy. Our will is to facilitate access to these renewable energies. How? 'Or' What ? By deploying hybrid and microgrid solutions, which maximize energy and storage efficiency.


We design intelligent instrumentation and automation systems for a cleaner world in the sectors of energy, industry and marine. Since 1959, we develop products innovative as well as personalized tools: intelligent sensors, monitoring systems advanced and automation. All these services are reserved to energy, industry and the marine industry.


Our virtues are those that guide our operations and advance our business. United, all employees who form our teams support our virtues and work ardently to promote them.

In addition , we educate our collaborators about the use of energy resources and limit use of & # 039; water, energy or even paper (recycling, communications, ...).

Energy and education are the guidelines of CSR policy. CMR is committed to deploy its own environmental and social project activities. All collaborators are involved in this challenge CSR.

CMR analyzes every year its carbon footprint for decrease it. Actions to perfect the transport of raw materials and finished products are at the center of its concerns.

CMR examines the life cycle of its products as well as the composition of raw materials to optimize waste recycling. The R & amp; D department focuses its efforts on the integration of sustainable development at all levels of society.

Use case

Energy and education are the guidelines of CSR policy. CMR is committed to deploy its own environmental and social project activities. All employees are involved in this challenge CSR.

CMR auscultates every year its carbon footprint in order to reduce it. Actions to perfect the transport of raw materials and finished products are at the heart of its concerns.


We design and deliver turnkey solar or hybrid power plants for micro-grid, industrial or grid-connected installations.

La solution HYDROS deployed by CMR makes it possible to hybridize diesel generator installations with solar production and potentially storage.

The transformation of thermal power plants into hybrid plants delivers many benefits to the customers of these facilities:

  • » major reduction in consumption of fuels
  • »Strong decrease in CO2 emissions
  • »Gain in competitiveness on the tariff of the electricity produced
  • »Decrease in maintenance costs .

Our HYLIOS solution is essentially intended for emerging countries strongly dependent on thermal production, but presenting significant solar potential.

The complexity of hybrid thermal power plants consists in the dimensioning of the equipment of the thermal part, the storage, and in the piloting. The goal is to deliver a continuous supply of electricity to customers.

Our HYLIOS solution is equipped with an energy flow management and control system, making it possible to meet the use of energy needs. This solution is usable for autonomous and nomadic mini-power plants but also for large hybrid ground installations.

Our energy management system offers many features for:

  • »Improve electrical efficiency
  • »Decrease the consumption of fuels
  • ' optimize self-consumption
