The paper discusses a simple looking but highly nonlinear regime-switching, self-excited threshold model for hourly electricity prices in continuous and discrete time. The regime structure of the model is linked to organizational features of the market. In continuous time, the model can include spikes without using jumps, by defining stochastic orbits. In passing from continuous time to discrete time, the stochastic orbits survive discretization and can be identified again as spikes. A calibration technique suitable for the discrete version of this model, which does not need deseasonalization or spike filtering, is developed, tested and applied to market data. The discussion of the properties of the model uses phase-space analysis, an approach uncommon in econometrics.

This paper analyses the increasing wind integration impacts on the Baltic region’s electricity market participants and power plant economics in the year 2025. Continuing subsidising impacts with currently implemented supporting mechanism is discussed. The last section addresses the key findings that large-scale wind integration, deployed under full market conditions, might have on the economics of different generation technologies, with and without subsidies.

Niniejszy artykuł analizuje rosnący wpływ elektrowni wiatrowych na uczestników rynku energii elektrycznej i ekonomię elektrowni w regionie Bałtyku do 2025 roku. W artykule omawiany jest również wpływ kontynuacji dofinansowania wg. przyjętego obecnie mechanizmu wspierającego. W końcowej części omówiono najważniejsze ustalenia, dotyczące potencjalnego wpływu wielkoskalowej energetyki wiatrowej, wdrożonej w warunkach wolnorynkowych, na ekonomikę zastosowania różnych technologii generacyjnych, zarówno z subsydiami jak i bez subsydiów.
