Power Purchase Agreements (PPA)
On-site PPAs are long-term electricity supply contracts in which renewable energy is generated and utilised directly on site at the customer's premises.
The property owner concludes a roof space utilisation agreement with us, while we sign an electricity supply agreement with the end user of the electricity (e.g. tenant, property owner).
We take over the complete project management, including financing, planning, realisation and operation of the system, as well as the entire project and financing risk.
Off-site PPAs are long-term electricity supply contracts in which electricity is purchased from a renewable energy source that is not located directly on site.
The defined amount of electricity is fed into the grid and, depending on the contract, is either supplied physically (‘Physical PPA’) or invoiced financially (‘Virtual PPA’).
This means that generation and consumption do not have to be in close proximity; settlement takes place via balancing groups.
Hybrid PPAs are long-term electricity supply contracts that combine several technologies - typically photovoltaics, wind power and battery storage.
This hybrid structure increases the security of supply and reduces the profile risks of individual energy sources.
Through the targeted use of storage systems, solar power or electricity from wind turbines, for example, can be stored at times of low value and fed into the grid at a later, economically more favourable time. This enables a more flexible supply of electricity and better adaptation to consumption.
PPAs offer numerous advantages: greener, cost-efficient electricity with long-term price security, planning reliability thanks to stable, calculable electricity costs, improved competitiveness and a sustainable corporate strategy.
In addition, the various PPA models offer specific advantages:
- Direct use of electricity on site without grid charges
- Can be flexibly expanded to include charging infrastructure, carports or storage solutions
- Improvement of the ESG rating through sustainable in-house electricity generation
- Independence of location - electricity from renewable sources without spatial restrictions
- Needs-based procurement of larger quantities of electricity, independent of own areas
- Transparency through guarantees of origin for the green electricity purchased
- Improved ESG rating through targeted use of renewable energies
- Greater security of supply thanks to the combination of several energy sources
- Reduced price volatility through optimised electricity supply
- Better grid integration through load control and intermediate storage
- Cost-efficient procurement of renewable energies with long-term price stability
- Increased sustainability through optimised use of renewable resources
- Supporting decarbonisation targets and maintaining the green characteristics of electricity
