Electrical energy efficiency is understood as the reduction in power and energy demands from the electrical system without affecting the normal activities carried out in buildings, industrial plants or any other transformation process.
Additionally, an energy effi cient electrical installation allows the economical and technical optimization. That is, the reduction of technical and economical costs of operation.
In short, a study on energy savings and efficiency will involve three basic points:
- Support the sustainability of the system and the environment by reducing greenhouse emissions as a result of reducing the energy demand.
- Improving of the technical management of the installations by increasing its effi ciency and avoiding stoppages and breakdowns.
- Reduction of the economical cost of the energy as well as the operating costs of the installations.
From a technical point of view, four basic points are considered in order to have a more efficient electrical installation.
- Contract optimizing
- Measurement systems
- Demand management
- Productivity improving by controlling perturbances and costs.
