Egypt and Ireland are pursuing ambitious renewable energy targets, yet both are confronting the same underlying reality: building renewable generation is only half the challenge. The electricity grid must be able to carry it. While the two countries are at different stages of their energy transition, their experiences highlight a growing issue for power systems worldwide. The constraint is no longer simply generating clean electricity, it’s ensuring the network can deliver it. Ireland’s challenge is already visible. According to RTÉ, the country curtailed enough wind power to supply around 667,000 homes during the first half of 2026 because the transmission system could not absorb all the electricity being generated. Wind Energy Ireland estimates that roughly 15% of the country’s lowest-cost electricity was effectively wasted due to grid limitations.
Ireland has developed one of Europe’s strongest wind power sectors. Instead, transmission constraints, limited storage capacity, and insufficient system flexibility are preventing the grid from using all the available renewable electricity. Egypt’s situation is different, but the underlying challenge is similar. Rather than curtailing large volumes of renewable energy today, Egypt is racing to expand its transmission network before renewable deployment accelerates further. The country has set ambitious targets to increase the share of renewables in its electricity mix while developing major solar and wind projects across the country.

To support those ambitions, Egypt has been investing in high-voltage transmission lines, grid modernization, battery storage, and interconnection infrastructure. The government is also seeking foreign investment to strengthen the electricity network and prepare it for much higher levels of renewable generation. The contrast lies in where each country sits on the transition curve. Ireland is experiencing the consequences of renewable generation growing faster than grid infrastructure. Egypt is attempting to avoid that outcome by expanding its transmission network alongside new renewable capacity, although financing and delivering those investments remain significant challenges. The comparison offers an important lesson for energy policymakers.
Renewable energy targets cannot be achieved through generation projects alone. Every gigawatt of new solar or wind capacity must be matched by investment in transmission infrastructure, substations, storage systems, and digital grid management. Without those complementary investments, countries risk either wasting clean electricity or slowing the pace of renewable deployment. This challenge is becoming increasingly relevant across emerging markets, including many African countries. Nations investing heavily in solar and wind will also need stronger transmission networks, faster grid connections, and greater operational flexibility if they are to maximize the value of those investments.
The experiences of Ireland and Egypt demonstrate that the next phase of the energy transition will be determined as much by the strength of electricity networks as by the amount of renewable capacity installed.
