Argentine energy company PCR has signed a five-year renewable energy supply agreement with Piedra Grande, an industrial minerals producer, to power three of its operational centres: Mercedes, Patagonia and NOA (North-West Argentina).
Under the contract, electricity will be sourced from the Mataco III and Vivoratá wind farms, both located in Buenos Aires province and operated by PCR. The renewable energy supply will cover a significant share of Piedra Grande’s industrial electricity demand, reinforcing the growing role of corporate power purchase agreements (PPAs) in Argentina’s renewable energy market.
The agreement reflects increasing demand for clean power from energy-intensive industries seeking to reduce their carbon footprint and enhance sustainability credentials amid global decarbonisation trends.
Ariel Costanzo, Director of Renewable Energy at PCR, said the deal strengthens the company’s position as a supplier of renewable energy to the corporate sector.
“This agreement with Piedra Grande reinforces the growth path we are pursuing as providers of renewable energy solutions for industrial clients. It demonstrates that it is possible to remain competitive while supporting companies in their transition towards a more sustainable energy model,” he noted.
Leonardo Bevilacqua, General Manager of Piedra Grande, highlighted the company’s environmental commitment: “At Piedra Grande, we believe the world is our home, and we work every day to ensure our production generates the lowest possible environmental impact.”
The partnership aligns with Piedra Grande’s sustainability strategy and with PCR’s broader objective of supporting industrial companies in adopting cleaner production models through renewable energy integration.
PCR is an Argentine-owned company with more than 100 years of experience in the country, operating across oil and gas, renewable energy and cement. In the renewables segment, it currently operates four wind farm complexes with a combined installed capacity of 545 MW across the provinces of Santa Cruz, Buenos Aires and San Luis.
With more than 540 MW of installed capacity across wind power and solar PV projects, PCR has consolidated its position as one of the most active renewable energy developers in Argentina.
Key renewable assets and milestones
| Project / Asset | Technology | Capacity | Location | Status |
|---|---|---|---|---|
| Mataco III | Wind power | — | Buenos Aires | Operational |
| Vivoratá | Wind power | — | Buenos Aires | Operational |
| Olavarría Wind Farm | Wind power | 180 MW | Buenos Aires | Approved, under development |
| Texas Solar Project | Solar PV | 30 MW | Texas, USA | Under development |
A recent milestone for PCR is the approval of its Olavarría Wind Farm under Argentina’s Regime for Incentives to Large Investments (RIGI). The 180 MW wind project will be developed in partnership with global steelmaker ArcelorMittal.
In addition to the wind farm construction, the project includes upgrades to the national transmission infrastructure. Works will be carried out at the Olavarría and Ezeiza substations, increasing evacuation capacity along the 500 kV transmission line connecting Bahía Blanca and Abasto. These grid integration improvements are critical for enabling large-scale renewable energy deployment in Argentina.
Since 2022, PCR has also been developing energy investment projects in the United States, including a 30 MW solar PV project in Texas. This move signals the company’s ambition to diversify geographically and participate in international renewable energy markets.
As Argentina’s corporate renewable energy segment continues to expand, long-term PPAs such as the agreement between PCR and Piedra Grande are expected to play a pivotal role in driving investment in renewables, grid modernisation and energy storage, while supporting industrial decarbonisation across the region.
