Naturgy is preparing a new investment drive in its electricity network in Spain. The company will allocate, through its distributor UFD, a minimum of 1.2 billion euros until 2029 to digitize and expand connection capacity. The objective is to improve the quality of supply, adapt to the growth in demand and facilitate the integration of renewables. In fact, the plan is at the maximum allowed and could be expanded depending on the approval of a future Royal Decree that will define the new investment plans in the networks.
And, with electrification and the advancement of the energy transition, distribution networks have become a key element in guaranteeing supply and absorbing new energy needs, from homes to large infrastructures such as data centers. The planned investments include the incorporation of advanced technologies such as telemetry, sensorization or remote control, to monitor the operation of infrastructures in real time. At the same time, the construction of lines and substations is contemplated, as well as the renovation of facilities to make them more efficient.
The company has already intensified this effort in recent years. In 2025 alone, UFD invested 408 million euros in Spain, 10% more than the average of the last five years, destined mainly to digitalization, innovation and service improvement. Currently, The distributor’s network exceeds 116,600 kilometers of high, medium and low voltage lines and serves nearly 3.9 million supply points.
The impact of these investments is also reflected in the quality of service. According to the company’s data, the average time that a customer remains without electricity supply throughout the year (interruption time equivalent to installed power or TIEPI, for its acronym) stood at 31.9 minutes at the end of 2025, an 11% improvement compared to five years ago.
In this sense, Mónica Puente, director of Spanish Electricity Networks at Naturgy, emphasizes that “the high volumes of investment in recent years have allowed the reliability of our service to reach 99.99%.” The directive also highlights that the objective is to “optimize the use of the network, expand capacity and guarantee resilience” in the face of increasingly frequent adverse weather events.
Regarding the territorial distribution of the investment, Galicia will concentrate the majority, with 519 million euros between 2026 and 2029, followed by Castilla-La Mancha (337 million), Comunidad de Madrid (217) and Castilla y León (145). This investment effort also has a social dimension: The activity associated with the network generates around 26,000 direct jobs, indirect and induced, especially in rural areas.
In parallel, the company will continue developing its Digital Services Platform (www.ufd.es) as a space where users can carry out all their transactions from any device. A new advance within the framework of the energy and technological transition planned for Spain in the next decade.
