[Webinar] Hybrids: A Path from Intermittency to Stability

In this webinar, Wärtsilä and Reuniwatt will outline a framework for the implementation of future-proof hybrid power projects. Adding solar power to an existing energy supply system allows hybrid plant operators to mitigate the risks associated with energy prices and at least partially decarbonize their operations.

Globally the energy transition is accelerating, driven by technology innovation and a significant decline in renewables prices. Despite the benefits of renewables to reduce emissions and cost of generation, intermittency remains a challenge.

Fortunately, the technologies and tools to address this intermittency challenge exist today. The final barrier to overcome is the effective implementation and integration of several technologies into one single dispatchable facility. Wärtsilä and Reuniwatt provide a framework for reliable and cost effective hybrid power plants. This will include technology integration, contractual structuring and system optimization, as well as the setup of a forecasting system as an essential tool for a smart energy management of hybrid projects.

After this webinar you’ll have an understanding of:

  • Why hybrid projects bring advantages for both on-grid and off-grid applications.

  • How to conceptualize solar hybrid projects and optimize their return

  • What is necessary for the technical integration of hybrid projects

  • The role and setup of a forecasting service
