Energy efficiency in industry can be defined as the search for lower consumption and energy optimization. It consists of maintaining - or even increasing - production levels and simultaneously reducing energy consumption.
The theme has become more relevant over the years, and in the industrial segment is increasingly understood. The power factor, for example, that affects the cost of electricity to be paid, is described in Aneel Resolution No. 414 of September 9, 2010:
Do more (or at least the same thing) with less, maintaining comfort and quality. When discussing energy, energy efficiency means generating the same amount of energy with fewer natural resources or getting the same service (“doing work”) with less energy.
In Brazil, the energy consumption of industries corresponds to almost 40% of the total energy produced in the country. Currently, the Energy Research Company (EPE) estimates that the energy efficiency potential in industries - that is, the volume of consumption that can be reduced by maintaining or increasing productivity - is 10.9% on average - 11.1 % in thermal energy consumption and 9.8% in electricity.
Barriers for their implementation may result from several factors. Some of them include:
- Information asymmetry : When a sector has relevant information, but does not share it with other sectors.
- Objectives Divergence : When the company prioritizes other objectives over energy efficiency.
- Commitment to energy issues : When the company does not emphasize the energy efficiency improvement program created and does not invest in measures to improve it.
To overcome barriers, it is necessary to improve the company's internal communication between the different sectors, set goals, clear objectives and greater compromise of leadership to the adoption of measures that achieve energy efficiency.
Electricity waste in a plant occur in various ways, work to identify, understanding how they happen and prevent them is important for reducing costs and generates three results. The first and straightforward is the very reduction in electric expenses, the second is the increase in performance and durability of the assets and finally, and as a consequence of the previous one, the reduction of maintenance costs.
Planning of energy efficiency improvement may involve several actions, but in general, investment in equipment modernization, reducing reactive energy surplus, combined with a monitoring system, can bring significant results in the medium or even short term.
Bridgemeter contributing to energy efficiency
Bridgemeter architecture flexibility is suitable for various fundamental measurements for energy efficiency monitoring allowing remote management of assets with alarm, notifications and predictive analysis.
To exemplify how Bridgemeter contributes to increasing energy efficiency, we present a case where the platform is still associated with a motor widely used by various segments.
Motobombas units monitored by Bridgemeter
Monitoring the electric current, temperature and correlating the values obtained with the other parameters that make up the equipment, Bridgemeter compares and provides analyzes with operational history, identifying trends that can evolve to overwhelming demand for work, sending notifications to customer maintenance team.
Thus, following the condition of use of the engine, it is possible to intervene to eliminate waste as part of the energy available is being lost in the form of heat, which contributes to the reduction of work efficiency causing premature wear and parts. This waste, if not monitored, generates increased costs, as well as the risk of unexpected stops.
Expanding the model described above, now applied to an industrial sanitation plant or a hospital with various engines, transformers and other electrical equipment that are part of the infrastructure, we find the importance of the theme of energy efficiency since the quote trend of electricity In the country is high.
According to the survey conducted in 2022 by the Brazilian Association of Large consumers and presented during the Energy Congress held by the Federation of Industries of Minas Gerais, the expense with electricity can represent up to about 40% of the cost of production.
“Energy waste has always been a challenge for companies. Currently, with Bridgemeter technology, it is possible to detect them and minimize their impact on both input cost and reducing maintenance spending, thus promoting increased efficiency in industries and other business units, ” says Flávio de Martin , Business Manager at Above-Net .
As can be seen, Bridgemeter is a strategic tool that directly contributes to financial and operational issues, reducing losses, increasing energy efficiency and productivity in industry.
