Key Takeaways
- Pays fixed, above-market rates for renewable energy.
- Offers long-term contracts of 10-25 years.
- Supports diverse small-scale renewable technologies.
- Tariffs decline over time to encourage efficiency.
What is Feed-In Tariff (FIT)?
A Feed-In Tariff (FIT) is a policy tool designed to encourage renewable energy production by paying producers a fixed, often above-market price for the electricity they generate and supply to the grid. Typically, FITs offer long-term contracts that provide financial certainty and stimulate investments in technologies like solar photovoltaic (PV), wind, and biogas.
This mechanism helps bridge the gap between the capital investment costs of renewable projects and their operating revenues, making green energy more competitive in the energy market.
Key Characteristics
FITs have distinct features that differentiate them from other renewable energy incentives:
- Guaranteed Grid Access: Producers are assured connection to the electricity grid, enabling consistent energy sales.
- Long-Term Contracts: Typically spanning 10 to 25 years, these contracts reduce investor risk and improve project financing options.
- Fixed or Sliding Tariffs: Tariffs are often based on the levelized cost of electricity (LCOE) and may decrease over time (digression) to reflect technological improvements and cost reductions.
- Technology-Specific Rates: Different renewable technologies receive customized tariff rates to prioritize development where needed.
- Size Limits: Many FIT programs apply to small-to-medium scale generation, usually up to 5 MW, to support distributed energy resources.
- Cost Recovery: Payments are financed through levies on electricity suppliers or consumers, spreading costs across the market.
How It Works
Under a FIT program, renewable energy producers install qualifying systems and enter into contracts with licensed suppliers who purchase their electricity at predetermined rates. These suppliers then pay producers based on actual generation, often verified by periodic meter readings.
This framework provides a predictable revenue stream that facilitates project financing and attracts early adopters of clean energy technologies. Over time, tariffs adjust to incentivize efficiency and reflect declining costs, ensuring ongoing market relevance.
Examples and Use Cases
Feed-In Tariffs have been successfully implemented worldwide to accelerate renewable energy adoption in various sectors:
- Solar Energy: First Solar benefits from FIT programs that stabilize returns for utility-scale photovoltaic projects.
- Wind Power: Companies like NextEra Energy leverage FITs to expand onshore wind generation with predictable pricing.
- Hydropower and Biomass: Iren participates in FIT schemes supporting small hydro and biogas plants, contributing to diversified renewable portfolios.

Important Considerations
While FITs provide strong incentives, you should consider the potential impact on electricity prices due to cost spreading across consumers. Additionally, as technologies mature and costs decline, FIT programs may evolve into competitive auctions or feed-in premium schemes.
Understanding the underlying discounted cash flow dynamics of renewable projects under FIT contracts can help you assess investment opportunities and risks effectively.
Final Words
Feed-In Tariffs provide long-term, stable payments that make renewable energy investments more predictable and attractive. To maximize benefits, assess current tariff rates and contract terms in your area before committing to a project.
Frequently Asked Questions
A Feed-In Tariff (FIT) is a policy that pays renewable energy producers a fixed, often above-market price for the electricity they generate and feed into the grid. This encourages investment in renewable technologies like solar, wind, and hydro through long-term contracts typically lasting 15-25 years.
FIT payments are based on factors such as the type of renewable technology, the size of the installation (usually up to 5 MW), location, and the amount of electricity generated. Tariffs often decline over time to reflect cost reductions and promote efficiency.
Renewable energy producers with installations generally up to around 5 MW, including solar PV, wind, hydro, and biogas systems, are eligible. Eligibility criteria can vary by region, but often include small-scale producers like homeowners with rooftop solar.
FIT contracts usually last between 10 and 25 years, depending on the technology type, installation size, and the commissioning date. For example, solar PV contracts in the UK can last up to 25 years.
FITs guarantee grid access and provide cost-based purchase prices through long-term contracts, ensuring price certainty and reasonable returns. This stable framework encourages investment by reducing financial risks for producers.
FITs originated from the 1970s U.S. Qualifying Facility incentives under PURPA, evolving into modern cost-based tariffs with guaranteed access starting with Germany's 2000 Renewable Energy Sources Act. This model spurred renewable growth globally, especially in Europe.
The costs of FIT payments are typically spread across electricity consumers or suppliers through levies or levelisation processes. This means the financial burden is shared to support renewable energy development.
Yes, while many countries have shifted to auctions or net metering as renewables have scaled, FITs remain important for promoting small-scale renewable energy deployment and providing stable incentives for new producers.
