This includes the proper synchronization of energy generation with the facility's electrical demand and compliance with protection and control requirements.
• Monitoring and Maintenance: Once implemented, self-generation systems require regular monitoring and proper maintenance to ensure their safe and efficient operation over time. This may involve installing remote monitoring systems, periodic inspections, and repairs as needed.

By considering these regulatory and technical requirements, companies can ensure a successful implementation, maximizing the economic and sustainable benefits for their businesses.

Distributed Energy Generation: What It Is and How It Works

Distributed energy generation, in turn, is a concept that refers to the decentralized production of electricity, where energy is generated on a small scale and close to the points of consumption. Unlike traditional large-scale centralized generation projects, such as hydroelectric or thermoelectric plants, distributed generation allows for multiple renewable energy sources, such as solar panels, wind turbines, or biomass systems, to be installed in homes, businesses, or communities.

This decentralized approach to energy generation offers several benefits, including the reduction of losses in electricity transmission and distribution, the improvement of the electrical system's reliability and resilience, and the promotion of sustainability by using clean and renewable energy sources.

Furthermore, distributed generation allows for greater consumer participation in the energy market, encouraging self-generation and the sharing of excess energy with the power grid. This active participation by consumers contributes to the creation of a more flexible, efficient, and adaptable electrical grid to modern energy demands.

Mechanisms and Models of Distributed Generation

There are several mechanisms and models of distributed generation that are used in different parts of the world to incentivize and facilitate decentralized energy production. Some of the most common include:

Net Metering: In this model, consumers who generate their own energy, usually through solar panels or other renewable sources, can send excess electricity generated back to the power grid. A bidirectional meter records both the energy consumed and the energy sent to the grid. Consumers are then compensated for the excess energy generated, which is credited to their electricity bill.

Feed-in Tariff: Under this model, renewable energy producers receive a guaranteed tariff for each unit of electricity generated and injected into the power grid. This tariff is usually set at a value above the market price of electricity, providing a financial incentive to invest in distributed generation systems.

Leasing and Power Purchase Agreements (PPAs): In these models, third parties finance, install, and operate distributed generation systems on consumers' premises. Consumers pay a fixed fee for the use of the energy generated by the systems, usually in the form of a lease or PPA, rather than buying and installing the systems themselves.

Energy Communities: This model involves the formation of local communities that collectively share and manage distributed generation systems. Community members can invest in shared renewable energy projects, participate in energy cooperatives, or share the benefits of energy generation on a local scale.

These are just a few examples of the mechanisms and models of distributed generation used around the world. Each model has its own advantages and challenges, and the choice of the most suitable model depends on specific market conditions, local regulations, and the participants' objectives.

Advantages of Distributed Generation

Distributed energy generation offers a series of significant economic, environmental, and social advantages:
