This isn't just a dream; it's a future that Wärtsilä's team of power system modelling experts are actively shaping. Their work, as revealed in our recent Wärtsilä Crossroads to Net Zero report, goes far beyond crunching numbers. It's about understanding the balance of energy supply and demand across the globe and charting a course towards a sustainable energy future.
The global energy landscape is undergoing a monumental transformation, driven by the need for decarbonisation and the increasing integration of renewable energy sources. As power systems become more intricate, the ability to accurately model and predict their future evolution is no longer a luxury, but a necessity.
At its heart, power system modelling, particularly within Wärtsilä's long-term techno-economic studies, seeks to navigate and understand the increasing complexity introduced by the surge of renewable energy sources. The fundamental question these models address is: how can we decarbonise our power systems effectively and economically?
Power system modelling is about creating a digital representation of existing and future energy systems. Think of it like creating a detailed blueprint of an energy system.
Rich in data, these models allow us to simulate various scenarios, identify optimal technology mixes, and chart pathways towards decarbonisation while minimising costs. By meticulously modelling current systems and projecting their future development, we provide valuable insights for energy companies, utilities, and policymakers alike, with the aim to deliver a clear pathway for achieving a sustainable energy mix.
With a portfolio of over 200 power system models spanning diverse countries and regions, Wärtsilä has gained a unique global perspective on the energy transition. What is interesting to note is the consistent patterns emerging worldwide.
Despite regional differences, our modelling consistently demonstrates that the transition to net-zero energy systems is not only technically achievable but also economically viable. While each country has its own unique situation, the basic steps to reach a zero-emission energy system are surprisingly similar across the globe.
Crafting accurate and insightful power system models is far from a straightforward task. Our experience has equipped us with a deep understanding of the intricacies and challenges found in power system modelling.
While incorporating every possible variable and data-point might seem ideal, the practical limitations of computational power and simulation time demand careful selection. Running highly detailed models can take days, highlighting the need for strategic simplification without sacrificing accuracy.
Additionally, the core of any effective model is reliable data. Our team will tell you that that data collection is a critical and often demanding aspect of their work; you can't just copy data from different places and hope it works. We carefully check every piece of information to make sure it all fits together and makes sense. Understanding the context of the data is just as important as the numbers, ensuring the model reflects real-world conditions and behaviours. This commitment to data quality is fundamental to the reliability and accuracy of our modelling outcomes.
Power system modelling is instrumental in guiding critical investment decisions. It enables stakeholders to visualise the optimal energy mix for the future, paving the way for cost-effective, reliable, and low-carbon energy power systems. Our modelling consistently highlights the transformative potential of combining renewable energy with flexible technologies, such as grid balancing engines and energy storage. This synergistic approach can unlock up to 80% renewable power, simultaneously lowering costs, enhancing system reliability, and bolstering energy security.
As the world accelerates its transition towards a sustainable energy future, the role of power system modelling becomes increasingly vital. Wärtsilä's extensive global experience and deep expertise in this field position us as a trusted partner in navigating this complex journey. By providing insightful and accurate models, we empower our clients to make informed decisions, paving the way for a cleaner, more affordable, and more secure energy future for all.
