Microgeneration refers to the small-scale production of heat or electric power from low-carbon sources, often as an alternative or supplement to traditional centralized grid-connected power systems. It involves generating energy on a small scale, typically at the point of use, using renewable or low-carbon technologies. Microgeneration technologies include solar PV systems, small-scale wind turbines, micro hydro systems, ground source heat pumps, microbial fuel cells, and micro combined heat and power installations.
Microgeneration allows individuals, households, or small communities to generate their own electricity or heat, reducing their reliance on fossil fuels and decreasing carbon emissions. It offers the benefits of energy independence, potential cost savings, and environmental sustainability. Microgeneration systems are often integrated with the regular electricity grid, allowing for the exchange of surplus energy and financial compensation through feed-in tariff schemes.
Where did microgeneration stem from?
The concept of microgeneration emerged as a response to the need for more sustainable energy solutions and gained traction during the 1973 oil crisis and the Yom Kippur War, which prompted innovation in the United States. Today, microgeneration technologies continue to evolve and provide a decentralized approach to energy production, empowering individuals and communities to contribute to a more sustainable and resilient energy future.
Use microgeneration to sell excess power to the grid
To sell power back to the grid in Northern Ireland, you have a few options depending on your specific circumstances.
Here are the steps you can take:
Install a renewable energy system
The first step is to invest in a renewable energy system such as solar panels or wind turbines. These systems will generate the electricity that you can sell back to the grid.
Connect to the grid
Your renewable energy system needs to be connected to the grid. This involves obtaining the necessary permits, inspections, and approvals from your utility company and local authorities.
Register for a Power Purchase Agreement (PPA)
Power NI, the main electricity supplier in Northern Ireland, offers Power Purchase Agreements (PPAs) that enable you to sell your energy back to them. PPAs are available for individuals or organizations installing renewable technologies such as wind, hydro, landfill gas, anaerobic digestion, or solar. You can enter into a PPA with Power NI, whether you’re a developer with multiple projects or an individual with a generator on your property. Power NI provides options for selling your exported energy and Renewable Energy Certificates (NIROCs).
Consider other suppliers
In addition to Power NI, other electricity suppliers in Ireland also offer the option to sell surplus solar electricity to the grid. Suppliers like Pinergy, Flogas, SSE Airtricity, Electric Ireland, Bord Gáis, and Energia provide varying payment rates for exported electricity.
Choose the best contract
When selecting an electricity supplier or entering into a PPA, it’s important to compare the export unit rates and payment terms. Different suppliers may offer different rates and payment frequencies, so it’s advisable to shop around and choose the contract that provides the highest value for your exported electricity.
Monitor energy production and consumption
Once your renewable energy system is connected to the grid and you have a contract in place, it’s important to monitor your energy production and consumption. Keep track of how much energy you generate and consume to ensure you sell the right amount back to the grid. Monitoring devices or apps connected to your renewable energy system can help you with this.
Receive payment
Depending on the contract or PPA you have chosen, you will receive payment for the electricity you sell to the grid. Payments can be credited to your account and used to offset any electricity consumed from the grid at a later date.
It’s worth noting that the specific rates, regulations, and processes may change over time, so it’s essential to stay updated with the current information provided by the utility companies, electricity suppliers, or relevant regulatory authorities in Northern Ireland.
Remember to consult with professionals or contact the electricity suppliers directly to get personalized advice and guidance tailored to your specific situation.
