The term Distributed Generation (DG) of energy refers to a model of electricity production in which energy generation is decentralized and occurs close to the place of consumption.. In this model, generation systems are installed in homes, businesses, industries or other buildings, allowing consumers to generate part or all of the energy they consume. In a Distributed Generation configuration, the main power generation methods include solar photovoltaics, which uses photovoltaic solar panels to convert sunlight into direct current (DC) electricity, subsequently converted into alternating current (AC) for use in buildings.

Distributed Wind Energy uses small wind turbines installed in urban or rural areas to harness the wind and generate electricity. Cogeneration Systems (CHP), also known as trigeneration systems, use waste heat generation in industrial processes or heating systems to generate electricity.

Already Gas Microturbine are small turbines installed in commercial or industrial buildings to produce electricity and take advantage of waste heat. Small Hydroelectric Power Plants (PCH) use small watercourses to generate electricity in a distributed manner.

Distributed Generation (DG) is an energy production model in which several generation sources are distributed on a small scale close to consumption sites, in contrast to the centralized model of large power plants. This decentralized approach brings advantages such as greater efficiency in transmission and less environmental impact. 

Photovoltaic solar energy is one of the most popular sources in DG. It uses solar panels to convert sunlight directly into electricity through the photovoltaic effect. These systems are installed on roofs of homes, commercial buildings or large solar farms, allowing consumers to generate some or all of their electrical energy locally.

Wind energy is obtained from the movement of the wind, which turns the blades of wind turbines to generate electricity. Yet, Distributed wind farms can be implemented in rural areas or even in urban areas, taking advantage of spaces such as industrial parks and port facilities.

Small and mini-scale hydropower harnesses the kinetic energy of water in smaller rivers and streams, using hydraulic turbines to generate electricity. This approach is more sustainable compared to large dams and dams that can cause significant environmental impacts. 

Already cogeneration, also known as Combined heat and power (CHP) is a system that simultaneously produces electrical energy and useful heat, such as steam or hot water. This technology increases the overall efficiency of the system by taking advantage of waste heat that would normally be wasted in conventional generation systems.

Therefore, The combination of several energy sources in Distributed Generation promotes greater diversification and resilience in the energy supply, in addition to reducing transmission losses associated with electrical energy transported over long distances. This approach contributes to an energy matrix more environmentally sustainable.

Distributed Generation (DG) offers significant benefits, both for consumers and for society in general. This implies reduction of transmission losses in large centralized power plants; electricity needs to travel long distances through transmission lines, which can result in significant energy losses. With DG, electricity production takes place locally, reducing transmission losses and improving the overall efficiency of the electrical system.

Increases the resilience of the electrical system, since energy production is distributed across multiple sources and locations. In the event of failures or natural disasters in a given area, other generation sources can still supply the local energy demand, ensuring greater supply reliability.

The energy sources used in DG, such as solar, wind and biomass, are renewable and have a lower environmental impact compared to fossil energy sources, such as coal and oil. Reducing greenhouse gas emissions and decreasing dependence on fossil fuels contribute to mitigating climate change.

Furthermore, the implementation and maintenance of DG systems, in some cases, requires local labor, which boosts the regional economy and generates jobs in communities where these systems are installed.

Distributed Generation allows also consumers to generate part or all of their own energy, which provides greater energy independence and freedom from energy price fluctuations in the market.

For this, it requires significant investments in transmission and distribution infrastructure. In DG, generation systems are implemented locally, requiring less expansion in the distribution network.

Yet, encourages research and development of more efficient and advanced technologies in renewable energy sources, energy storage and control systems, accelerating the adoption of cleaner and more sustainable solutions. Companies and industries that adopt Distributed Generation can take advantage of economies of scale and gain a competitive advantage, in addition to reducing energy costs over time.

DG can be combined with the adoption of electric vehicles, allowing the charging of these vehicles from renewable energy sources, making transport more sustainable, as well as reduce peak demand on the electricity grid, as local generation can meet part of the demand during peak consumption times, reducing pressure on the system at critical times.

Given this context, it applies a series of advantages that contribute to building a more sustainable, efficient and resilient energy system, aligned with the objectives of combating climate change and improving the quality of life of local communities.

Distributed Generation (DG) is a viable option for countless consumers and entities, from homes to large industries. Basically, any electricity consumer who has the possibility to generate their own electricity can adopt Distributed Generation.

Given this, Distributed Generation is an affordable and flexible solution – adopted by different types of consumers – whether residential, commercial, industrial or institutional, provide economic, environmental and social benefits for all involved.

Distributed Generation (DG) is a form of electricity production in which generation occurs in small units close to points of consumption. To adopt Distributed Generation, it is necessary to invest in specific equipment for the production of electricity at the consumer's facilities. The types of equipment needed vary according to the energy source used. Some of the main sources of energy for DG are solar photovoltaic, wind, biomass and cogeneration (CHP – Combined Heat and Power).

To generate electricity from sunlight, photovoltaic solar panels are needed. These panels convert sunlight into electrical energy and are installed on roofs or other areas exposed to the sun. In wind energy generation, wind turbines or wind turbines are used, which capture wind energy and transform it into electricity. In the generation of energy from biomass, equipment such as boilers, furnaces or generators powered by biomass, such as agricultural and forestry residues or organic residues, is required. Finally, in cogeneration, equipment is used that produces electricity and heat at the same time, such as gas turbines coupled to cogeneration systems.

In this way, the adoption of Distributed Generation can offer numerous advantages, such as the reduction of losses in energy transmission, greater resilience of the electrical system and contribution to the sustainability and decentralization of the energy sector. However, it is important to emphasize that the viability of Distributed Generation can vary according to the specific conditions of each consumer.

The equipment used in Distributed Generation is designed to be efficient and durable over time, with a useful life that can vary from 15 to 25 years, depending on the type of technology and the quality of the equipment used.

Despite initial investments, Distributed Generation has long-term economic advantages, since operation and maintenance costs are generally lower compared to conventional centralized generation systems. However, before adopting it, it is essential to carry out a specific technical and economic feasibility study for each case, considering the costs, benefits and characteristics of the consumer's energy consumption profile.

To adopt Distributed Generation (DG), some technical requirements must be considered in order to ensure proper integration of the local generation system with the existing electrical grid. Before implementing a DG system, it is essential to carry out a feasibility study to assess the possible generation capacity, the local energy demand, the characteristics of energy consumption throughout the day and the space available for the installation of equipment.

To connect the DG to the existing electrical grid, it is necessary to obtain permission and follow the guidelines of the regulatory authorities and the power distribution company. A connection contract may be required, with technical specifications to guarantee system security and stability.

That said, it is essential to install a bidirectional metering system to measure the amount of energy consumed from the electrical grid and the amount of surplus energy that is injected into the grid during periods of surplus generation. This meter allows the correct accounting of energy credits.

DG systems must meet electrical protection requirements to ensure people's safety and network stability. This may include overvoltage, short circuit, and overload protection devices.

Yet, the GD must guarantee the quality of the energy supplied to the electrical grid, meeting the frequency, voltage and harmonic distortion standards established by regulatory standards.

The introduction of DG into the power grid can affect the stability of the system if not properly designed. It is important to consider DG's ability to meet local demand and generation fluctuations, especially in solar and wind energy systems, diversifying according to weather conditions.

It is crucial that the equipment used in DG meet applicable standards and certifications, ensuring its safety, efficiency and compliance with technical standards.

A preventive maintenance plan also must be implemented to ensure the continued good functioning of DG systems. In addition, it is important to monitor energy generation and consumption to optimize performance and identify potential problems.

By meeting these technical requirements, the adoption of Distributed Generation apply significant benefits for consumers and the electricity grid, promoting a cleaner, more resilient and sustainable energy matrix.

The adoption of Distributed Generation (DG) is encouraged by government programs and policies, as well as by measures adopted by companies and energy concessionaires. These financial incentives aim to make the implementation of DG systems more accessible, stimulating the transition to renewable and sustainable energy sources. It is presented within this context:

• Energy Credits (Net Metering): Many countries and states adopt the system of net metering, which allows DG system owners to receive credits on the energy bill for the excess energy generated and injected into the electrical grid. These credits can be used to offset energy consumption during periods when DG is not generating enough energy to meet demand.
• Subsidy Programs and Tax Incentives: Governments and regulators offer subsidy programs and tax incentives to reduce the initial costs of installing DG systems. That includes Income Tax discounts, exemption from taxes on equipment and materials, or lines of credit with lower interest rates to finance the acquisition of systems.
• Renewable Energy Laws: Some regions have renewable energy laws that set mandatory targets for the adoption of clean energy sources. This may encourage companies and individuals to invest in GD as part of their compliance strategies with these laws.
• Special Financing: Some financial institutions offer specific lines of credit for DG projects, with more attractive financing conditions, such as long terms and reduced interest rates.
• Energy Auctions: In some countries, renewable energy auctions are held, on what the projects of GD compete to sell the energy generated at competitive prices to concessionaires or distribution companies.
• Green Energy Programs: Energy companies and utilities offer green energy programs that allow consumers to the choice of pay an additional amount to support DG projects and other renewable sources, increasing demand and investment in clean energy.
• Renewable Energy Certificates (RECs): In some regions, renewable energy certificates are issued for each megawatt-hour (MWh) of renewable energy produced. These RECs can be commercialized, providing an additional source of revenue for DG system owners.

Therefore, it is recommended that those interested in adopting Distributed Generation seek updated information from government agencies, energy concessionaires and financial institutions to learn about the incentives available in their location. these incentives do a big difference in the return on investment and economic viability of DG projects, making them even more attractive to consumers.
