Investments in renewable energies Energy mix in Poland and Germany: differences and opportunities for investors

Why does comparing the Polish and German energy mixes matter for investors

Many investors use Germany as a benchmark when assessing projects in Poland. This quickly leads to flawed assumptions, for example, about grid electricity emissions, price risk, evidentiary standards or grid-connection realities. A structured comparison helps anchor the starting point realistically and increases the resilience of business models.

Typical reasons for comparison:

• Investments in sustainable, electrified real estate with high energy demand
• Investments in companies for which energy is a material cost component
• Projects with green energy strategies and ESG reporting obligations
• Transactions where decarbonisation is part of the investment thesis

Energy mix in Poland and Germany: what are we actually comparing?

For investors, it is essential not to confuse the overall energy mix with the electricity generation mix. The energy mix describes the entire economy’s use of energy: power, heat, industrial processes and transport. The electricity generation mix describes the composition of sources in power production. Many investment effects only become visible when these layers are analysed separately.

Key differences in the starting point

The most important difference lies in the structure of generation, and thus in emissions intensity and price logic. Germany and Poland have different histories, infrastructure and transition speeds. This shapes market mechanics and the requirements placed on investors.

Differences are typically visible in:

• The share of fossil fuels and their role in price formation
• The pace and structure of RES deployment
• System flexibility, grid expansion and regional constraints
• The importance of imports and cross-border effects
• Corporate governance, reporting and evidentiary logic in projects

Impact on ESG: why the same kWh does not have the same effect

In ESG, not only consumption but also context matters. The same kWh can have different emissions depending on the country. For investors, this means that Scope 2 values, decarbonisation pathways and sustainability statements must be assessed in a location-specific way.

In practice, the following are critical:

• Scope 2 classification and the data backbone for reporting
• Evidentiary logic for substantiating “green” attributes (environmental characteristics)
• The risk of generic sustainability claims without robust, credible documentation

Impact on business models: price risk, grid and planning capability

In comparisons, not only average prices matter, but especially volatility, contract logic and the likelihood of obtaining grid-connection terms. In electrified assets, the energy price is a key multiplier, and grid connection can be a critical project bottleneck.

Relevant for business models:

• Sensitivity to fuel and CO₂ costs as primary cost drivers
• Load profile, peak values and grid cost parameters
• Connection capacity, expansion options, timetable and costs
• Risk mitigation via contractual models and structured power procurement

Opportunities for investors: where differences can work to your advantage

Differences are not only risks — they are also opportunities. Investors can benefit if they realistically price the starting point and structure projects so that decarbonisation becomes plannable.

Typical opportunities:

• Value-add potential through modernisation, efficiency improvements and electrification
• Green energy strategies as a driver of tenant demand and an exit factor
• Portfolio approaches, where multiple locations are implemented in a standardised way
• Early grid and connection planning as a source of competitive advantage

Common mistakes in comparison – and how to avoid them

Many mistakes arise from automatically transplanting German standards into Polish realities. Frequent pitfalls include:

• Business models based on German price assumptions without local granularity
• Underestimated connection lead times and grid expansion costs
• ESG declarations without solid data and structured evidentiary processes
• Contract models that do not reflect load profiles and risk allocation

Checklist: quick DE–PL comparison test

For initial screening, the following questions help:

• What is the starting energy and electricity situation of the asset?
• How sensitive is the IRR to price and emissions assumptions?
• What evidence is required for ESG and financing?
• Is connection capacity secured and scalable?
• Which contractual mechanisms hedge price, supply and reporting?

Conclusions: the energy mix in Poland and Germany

Comparing the Polish and German energy mixes helps investors avoid flawed assumptions and identify opportunities. The key is to analyse the overall energy mix and the electricity generation mix separately, to safeguard business models through scenario planning, and to operationalise ESG and procurement via appropriately adapted processes and contracts.
