Prysmian reports that it has been awarded a framework agreement with Italy’s Terna—which is responsible for the management, maintenance and development of the country’s high-voltage electricity grid—to support the strengthening of the Italian power grid.

A press release said that the framework agreement is for three years and includes an additional year which may be optioned by Terna—that has a potential total value of €382.5 million. Terna is one of the largest independent grid operators in Europe. As part of the agreement, Prysmian will supply Terna with HVAC cables, as well as maintenance of high voltage cables.

Terna is expected to acquire at least 50 km of high-voltage cable each year, a number that could rise considerably in line with their requirements. Based in Rome, Terna manages about 98% of Italy’s high-voltage and extra-high-voltage electricity transmission grid, operating over 75,000 km of power lines.

The award is aligned with Terna’s strategy for the development and modernization of the national transmission grid, aimed at supporting the objectives outlined in the European Green Deal and the Integrated National Energy and Climate Plan. Prysmian will make use of its extended facilities in Pignataro Maggiore, Campania, to manufacture these cables. That site recently received over €20 million in investment to support an increase in capacity, including in high voltage cables.

Prysmian Europe CEO Marcello Del Brenna said the deal was positive on multiple levels. Prysmian will help Terna improve its power grid and bolster progress for its energy transition while supporting the overall Italian economy by making the cables at its Pignataro Maggiore factory in Caserta. Added Italy Country Manager Fabio Zucca, “This framework agreement is an important commitment, from both Prysmian and Terna at a critical moment in the energy transition, and we are proud to have been entrusted with this significant award.”

Prysmian has secured a contract to supply approximately 740 km of submarine fiber optic cable for the Hawaiian Islands Fiber Link (HIFL) project, a cornerstone infrastructure initiative designed to deliver equitable broadband access across all six main Hawaiian islands by late 2026.

A press release said that the HIFL cable system represents a critical component of the Hawaiʻi’s Connect Kākou initiative to provide reliable broadband service to all residents, businesses, educational institutions and government facilities. The submarine cable system will span approximately 416 miles of seabed between islands, with cables ranging from 1.1 in. in diameter in shallower waters to about 0.6 in. at maximum depths. The installation will connect cable landing sites on Kauaʻi, Oʻahu, Maui, Lānaʻi, Molokaʻi, and Hawaiʻi Island.

Each cable landing site will employ horizontal directional drilling to traverse underneath shorelines to offshore connection points, minimizing environmental impact while ensuring secure cable placement. The system design incorporates 24 fiber pairs with a 25-year operational life expectancy.

Prysmian Group has won the “Quick & Simple Substation” innovation challenge organized by Dutch grid operators Alliander, Enexis and Stedin, beating out 13 other submissions with a solution aimed at accelerating the installation of medium-voltage (MV) substations.

A press release said that the challenge focused on identifying scalable methods to strengthen Europe’s power grid infrastructure in response to rising electricity demand and grid modernization pressures linked to the energy transition.

Prysmian’s winning concept features a plug-and-play MV cable solution that uses a flexible prefabricated cable with plug-in connections. The design simplifies the substation installation process, reducing time on-site and enabling faster, technician-friendly deployment. The modular system is intended to be scalable and repeatable, helping utilities reduce reliance on specialized labor and keep up with aggressive grid expansion timelines.

The solution will be initially rolled out in the Netherlands but is designed for wider adoption across international markets. According to Prysmian, the approach offers a template that could benefit hundreds of power networks worldwide through faster grid upgrades and improved system resilience.

Prysmian has completed a 51,000-sq-ft expansion of its Williamsport, Pennsylvania, facility, adding 27 permanent jobs as part of a broad supply and manufacturing agreement with Invenergy, a leading independent power producer.

A press release said that the expansion, representing a $22.5 million investment, will directly support Invenergy’s Grain Belt Express transmission line—currently the largest private-sector-led transmission project in the U.S.—using domestically sourced steel and aluminum for advanced power conductors. The Grain Belt Express will span from Kansas to Indiana, delivering renewable energy to millions and reinforcing grid reliability.

With the expansion, Prysmian doubles its U.S. manufacturing capacity for key advanced transmission conductors, including those that utilize its E3X® technology. The company’s Williamsport site is now positioned as a critical hub in both Prysmian’s and Invenergy’s investments in U.S. energy infrastructure, jobs and supply chains. The plant supports over 270 jobs locally and more than 430 across Pennsylvania.

“We are proud to have a part in this transformative project supplying our most innovative technology for overhead power transmission in the market, E3X®,” said Andrea Pirondini, Prysmian North America President and CEO. “Our expanded Williamsport facility enhances our manufacturing capacity and is another step to strengthening the grid and granting energy independence throughout the United States.”

Prysmian held a groundbreaking ceremony on June 19 at the Encore Wire campus in McKinney, Texas, which will undergo a massive expansion, part of a $500 million project over five years that will see the addition of a state-of-the-art medium voltage cable production facility totaling more than 650,000 sq ft.

A press release said that the investment includes $249 million Prysmian’s Board of Directors approved earlier this year. The groundbreaking “marks a significant advancement for the company, nearly a year after Prysmian’s acquisition of Encore Wire to serve electrical customers in North America through Encore’s outstanding service model.” Expected online in 2027, the plant will significantly increase Prysmian’s medium voltage capacity and add 120 new jobs.

“This new plant will be one of the largest standalone facilities on our campus, which is the largest vertically integrated cable factory on the planet and is a major milestone in the Prysmian/Encore Wire growth,” said Prysmian North America CEO Andrea Pirondini.

Encore Wire started in 1989 with a 68,000 sq-ft industrial warehouse building in McKinney. Over the past 35 years, Encore has grown to over 3.5 million sq ft across 460 acres.

In addition to Prysmian leaders, U. S. Representative Keith Self’s District Director Michelle Bishop presented a Congressional certificate to Pirondini marking the importance of this investment. Governor Greg Abbott also issued a proclamation commemorating the groundbreaking. McKinney’s new Mayor Bill Cox joined other local leaders for the ceremony, including the Michael Kowski from McKinney Economic Development Corporation (MEDC).

Guests signed a commemorative beam that will be placed in a prominent location in the new facility. The medium voltage plant is the first phase of Prysmian’s investments in McKinney. For more on the vertically integrated campus, visit Encore Wire’s website.

Prysmian has formed a partnership with Dow to advance the production of the company’s Sirocco® microduct cables that uses Dow’s AXELERON™ telecom cable compound.
