Iberdrola continues to expand its electricity network portfolio in Spain with the acquisition of Electra del Maestrazgo’s operations, a family-run company based in Castellón. The acquisition includes 1,350 km of medium- and low-voltage power lines, 21,000 supply points, 19,000 retail customers, and 6.8 MW of installed capacity from photovoltaic and hydroelectric plants. These assets will strengthen the company’s position in the provinces of Castellón and Teruel.
The transaction aligns with Iberdrola’s overall strategy, which focuses on expanding its electricity networks and making selective investments in renewable energy. In response to increasing electrification demands, Iberdrola plans to invest more than €13bn ($14.13bn) in its networks between 2025 and 2026. This is part of its objective to raise the value of its regulated network assets to €51bn ($55.45bn) by the end of the year, up from €49bn ($53.27bn) reported in the first quarter of 2025.
The Electra del Maestrazgo family will continue managing local infrastructure while benefiting from Iberdrola’s greater investment capacity. The acquisition is subject to approval by the Comisión Nacional de los Mercados y la Competencia (CNMC – National Commission on Markets and Competition) before it can be finalised.
Strategic acquisition for Iberdrola
This strategic move strengthens Iberdrola’s position in the Spanish energy market, particularly in electricity distribution and supply. Electra del Maestrazgo, founded in the 1950s, has a longstanding history in local energy infrastructure management. Integrating these assets will allow Iberdrola to further diversify its electricity network in Spain and enhance its management capabilities.
The acquisition of 6.8 MW of renewable energy, although modest relative to Iberdrola’s total portfolio, reflects its commitment to integrating sustainable energy solutions. The company plans to significantly increase investments in distribution infrastructure to support the energy transition while addressing rising energy consumption needs.
Reinforced investment in electricity networks
Iberdrola intends to strengthen its distribution network through acquisitions of this nature, as electrification becomes a major driver in the energy sector. The company has already announced plans for sustained investment in its infrastructure, enhancing its electricity network management capacity to meet future demand. By consolidating investments in strategic assets, Iberdrola continues to prepare for a rapid energy transition while benefiting from scale and activity diversification.
