Did you know: Excess energy from renewable energy sources can lead to blackouts in the Greek power grid and jeopardise electrical appliances?
What to Expect This Easter
During the Easter period, the energy supply system is facing significant challenges.
Last year, a reduction of 2,500 MW was necessary to prevent system failure
This year, the situation is more complex. The installed renewable energy sources (RES) have increased by another 2,500 MW, leading to concerns about excess energy.
During this season, potential issues arise from the overlap of Orthodox and Catholic Easter, making it difficult to export surplus energy.
With favourable spring weather conditions contributing to high energy production (lots of wind for wind turbines and lots of sun for solar panels) yet low consumer demand (no heating or air conditioning required), the excess energy may not be efficiently utilised.
The system lacks adequate storage units, which raises the possibility of waste if surplus energy cannot be dispatched.
Affected Parties
The reduction in energy output primarily impacts projects connected to the network of the Independent Power Transmission Operator (IPTO). This includes large wind and solar farms that are heavily dependent on the ability to manage energy supply effectively.
In contrast, the Distribution Network Operator (DNO) manages lower voltage networks, but lacks the real-time monitoring equipment to implement similar energy reductions.
This situation poses a unique challenge for the electrical supply system, testing its capability to handle increased production levels while ensuring stability.
The potential for excessive output from renewable resources highlights the need for careful management across these electricity networks, especially during peak holiday times.
The great potential of the renewable energy sector in Greece, which now has an installed capacity of 14.5 gigawatts (of which 8.5 to 9 GW in HEDNO), harbours risks due to the imbalance between production and consumption, which can only be countered by massive cutbacks.
It is estimated that a total of 7,000 MW of photovoltaics are in the ‘red zone’, which must be kept on standby in order to be able to switch off energy when required.
Compensation Mechanism
To counteract the risk of blackouts during the Easter holiday, a new strategy will be employed.
Stakeholders, including representatives from both IPTO and DNO, will convene to assess the current situation and develop a clear plan.
This includes updating load forecasts and organising any necessary energy reductions.
The compensation mechanism will help ensure that the system remains operational during peak demand times.
Through careful coordination, the aim is to prevent any operational failures and support consumer needs effectively.
This proactive approach is crucial in maintaining service reliability while navigating the complexities of energy production and consumption during this festive period.
Frequently Asked Questions
What are the effects of a large-scale power outage during festive periods?
A widespread power failure during holiday seasons can lead to many problems.
This includes disruptions in essential services, safety concerns, and significant economic losses for businesses.
Additionally, it can cause distress and inconvenience to households that rely on electricity for heating, cooking, and other daily activities.
What steps should households take to ensure safety in case of a power outage?
In the event of a power cut, households should remain calm and check to see if neighbours are also affected.
They should avoid opening refrigerators and freezers to keep food cold for longer. Using battery-powered lights rather than candles is safer, and having a plan for emergency contact can help keep everyone informed.
How does electricity demand during Easter compare to typical days?
Electricity demand during Easter often sees significant spikes due to increased cooking and entertainment activities.
Households tend to use more appliances, and this can place additional strain on the grid.
Understanding these trends helps authorities manage resources effectively to ensure reliable power supply.
