There is a delicate and blurred line between investments into the sustainable energy technologies and security of supply. Both are overreaching concepts that describe a multitude of approaches. At the core is the attempt to upgrade technologies with a low environmental impact while ensuring energy resources (primary and secondary) are secure. Creating a sustained momentum of investments through a clear trajectory is core to an efficiently managed system. The sustained trajectory towards a more secure and environmentally sustainable energy system is where countries in Central Europe fall short.
In Europe, there is a clash of how embedded energy systems contribute to energy security. There are two distinct approaches, one in older member states (UK, France, Germany) and one in newer eastern member states (e.g. Poland, Hungary, Bulgaria). Some countries transformed their energy systems in a rapid manner, like Germany and Spain, where solar and wind received a tremendous boost through feed-in tariffs. This transition is now self-sustaining due to the drop in the cost of technologies and a mature domestic service industry. While Spain cut off financing the industry became well established. In Germany, support remains and the renewable sector will continue to grow.
More broadly, the transformation boosted both countries’ energy security while moving them towards a sustainable energy system. Both environmental and commercial reasons (being leaders in energy technology) fueled this conversion. Spain reduced its oil imports while Germany reduced coal (temporarily) and nuclear power in their energy mixes. Social support existed in both countries for this transition.
Energy technologies in the SCEE region
Building a sustainable technological trajectory to transform energy systems is not occurring in South and Central Europe. Some countries, like Poland, Hungary and Bulgaria have not noticeably altered their energy systems. In fact, these countries are marked by a reassertion of their older technologies. Renewable energy technologies are kept to the minimum EU requirement which is below 20%, and little or no government financial incentives. Instead, these countries are clearly reliant on extending and expanding their current energy technologies. Poland will maintain a high mix of coal in electricity generation, currently this is near 90%. The overall 2050 energy mix is projected to have 60% from coal, 20% from gas and 20% from renewables. Thus a rough projection can see electricity generation from coal being around 70%, while boosting gas and renewables in electricity generation.
Hungary is set to increase nuclear power to over 70%, by expanding its nuclear plant. If life extensions are done for current reactors, then by 2050, this 70% ratio could remain in place. Electricity generation from coal and gas and some renewables will remain. Thus, Poland and Hungary pursue a 70% mark for their electricity systems based on previous technologies. This percentage, when combined with gas, effectively locks out renewable energy to any meaningful degree.
Poland’s Electricity Generation Mix
The energy mix of Bulgaria, from the outside, is diverse. It is a net exporter of electricity and has hydro, nuclear and renewable energy (wind and solar). However, as I will explore elsewhere on this blog, there are systemically high costs associated with Bulgaria’s solar feed-in tariffs, expensive long term contracts for coal-fired power plants, and the general overcapacity of nuclear power, which means even this ‘cheap’ source of energy either needs to be exported or (at times) taken off line due to the oversupply from solar and coal. The future of the Bulgarian energy system, while on the face of it, appears nuclear and centralized, consistent mismanagement may result in technologies with shorter payback periods dominating the energy mix, such as gas and renewable technologies.

Technology and Resource Dependency
The choice of Poland and Hungary to maintain their future energy mix at 70% based on technologies from the previous energy era are directly connected to the perceived final price of electricity, gas and energy supply security. Bulgaria continues to debate and engage with reliance on Russian nuclear technology and gas pipelines – on the same level as Hungary. Bulgaria lacks the momentum to diversify away from Russian resources and technologies. All three countries are affected in their choice of energy systems by Russian control of resources and technologies. New investments fall into one or both of the categories of resource in/dependency and technology in/dependence.
The future energy systems in these countries are based on the previous Communist energy technologies and resources. This is not a trajectory that moves these energy systems towards being both sustainable and secure. Rather, ‘cheap coal’ and ‘cheap nuclear’ are perceived to provide the affordable energy that the citizens of these countries accept. The competitive advantage deriving from ‘cheap’ resources and technologies rests on the previous Communist energy complex. Today, these facilities are built under considerably different market conditions than what we have today or in the future.
It is the difference between the old political-economic regime and the one that exists in the EU that is a source of friction today. Financing of the expansion of Hungary’s Paks NPP is now provided by Russia. Russia attempts to influence the future energy choices of the region by extending the previous political-economic system of resource and technology dependency. This will be discussed in the next blog post.
