Imagine a world powered entirely by clean energy, systems that are not only environmentally sound but also economically efficient and reliably delivered. Our team of power system modelling experts are actively shaping this future. They are creating the blueprints for the power systems of tomorrow.
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. Discover our findings in the white papers and reports below.
Power system modelling involves creating digital representations of energy systems to simulate scenarios, optimise technology mixes, and chart pathways to decarbonisation.
Wärtsilä's expertise helps navigate the complexity of renewable energy integration, providing insights for different regions, customers and policymakers. Our models show that transitioning to net-zero energy systems is achievable and economically viable, supporting stakeholders in making informed decisions for a sustainable energy future.
This report evaluates two commonly considered pathways to achieve net-zero emissions in the power sector at a global level.

This white paper explores a new path that would enable California to meet its goal of 100% clean electricity by 2040 — five years ahead of schedule.
While emissions have decreased, the rapid growth of renewables has introduced new challenges.

What are the most cost-effective ways forward for the country’s power sector?
Accelerate renewables to tackle energy costs and increase energy independence. The modelling shows a clear positive impact on reducing Europe’s exposure to the gas market, its carbon emissions and the cost of electricity - leading to lower bills for consumers.
Germany can achieve significant emission reductions and lower electricity bills by phasing out coal in 2030. But, the country must have a clear plan to ramp up renewables and pivot to sustainable fuels to achieve net zero.

The recent rapid growth of wind and solar-generating capacity in Ukraine, supported by high feed-in tariffs (FITs), has put financial and technical pressure on the power system and sparked a debate about the country’s ability to sustain this trend.

Despite the diversity of the African countries, the ingredients of the energy transition are the same for every nation. Renewable energy, supported by flexible balancing capacity, is the most effective way to replace inflexible generation, reduce energy costs, increase energy access, and improve reliability.
This paper looks at both the adequacy of South Africa’s proposed energy crisis mitigation measures and the role that gas power plays in this context along with providing a view on how gas power can support South Africa’s energy transition to 100% renewables.
Nigeria has set some of the most ambitious decarbonisation targets in Africa. The country seeks to take the lead in climate action and aims to achieve carbon neutrality by 2060 whilst also meeting the nation’s growing energy needs and offer universal access to electricity to its population. How can the country achieve this?
Mozambique has the largest power generation potential in the entire Southern African region thanks to its vast and largely untapped gas and renewable energy resources. Despite this huge generation potential only around 40% of its population had access to electricity in 2021. How can the country achieve electricity for all optimally?
