Why Did Romania Pay the Highest Energy Prices in Europe Yesterday?
Romania experienced the highest energy prices in Europe yesterday, not due to expensive domestic production, but because of a confluence of factors during a moment of grid stress. The country's primary energy sources, Cernavodă nuclear power and Hidroelectrica, are among the cheapest in Europe, producing energy well below 35 euros per MWh. The only genuinely expensive component in Romania's energy mix is coal, whose price is significantly inflated by the cost of CO2 certificates. This expensive coal drives up the price of the entire energy mix whenever it is activated. Yesterday's high prices were a result of a simultaneous lack of three critical elements: available firm capacity, sufficient energy storage, and robust interconnection capabilities.
The event highlights a critical vulnerability in Romania's energy system: its reliance on expensive, carbon-intensive sources like coal, which dictates market prices even when cheaper alternatives exist. The simultaneous deficit in firm capacity, storage, and interconnection suggests systemic underinvestment in grid resilience and flexibility. This situation underscores the challenge of balancing energy security with decarbonization goals, particularly in the context of evolving European energy markets and climate regulations. Future policy should focus on diversifying the energy mix, enhancing grid infrastructure, and exploring advanced storage solutions to mitigate price volatility and ensure reliable supply.
