IMPSA’s origins date back to 1907, when Enrique Epaminondas Pescarmona founded Talleres Metalúrgicos Pescarmona in Mendoza (Argentina) to manufacture cast iron spare parts, winemaking equipment, and gates for irrigation canals.

Construcciones Metálicas Pescarmona S.R.L. (“CMP”) was set up to undertake the design and construction of metal structures, irrigation gates, and other electromechanical equipment.

IMPSA –acronym for Industrias Metalúrgicas Pescarmona S.A.I.C. y F.– lent continuity to the company founded in the early 20th century and embarked on the design and construction of large steel structures and electromechanical equipment.

A remarkable process of technological development turned IMPSA into an innovative company and made it a leader in hydro generation in Argentina.

IMPSA became an international benchmark for the construction of port cranes and turnkey hydro power plants by implementing an aggressive R&D policy and building its own Technology Research Center.

IMPSA secured its position as a hydro project developer in the energy market with two important B.O.T. (Build, Operate and Transfer) contracts: Potrerillos in Argentina and CBK in the Philippines. Wind energy research began.


  • IMPSA created the Wind Business Unit gambling heavily on wind energy with high-tech wind turbines.
  • IMPSA was awarded a contract for manufacturing the Kaplan turbines with the highest output ever built for Venezuela’s Tocoma Hydro Power Plant.
  • IMPSA provided cranes for the Port of Tanjung Pelepas (PTP) in Malaysia.
  • EPC contracts were signed with the Province of La Rioja (Argentina) for the supply of twelve 2.1 MW IWP-83 wind turbines designed by IMPSA for the Arauco I Project and for the operation and maintenance of the wind farm.

2010 to the present

  • IMPSA was awarded the Arauco Stage III contract for 12 wind turbines for an additional 25.2 MW of installed capacity, which was subsequently expanded to 52 MW with IMPSA’s supply of 26 IWP-100 wind turbines for Arauco Stage IV.
  • IMPSA opened a brand-new Clean Room, where four replacement steam generators were manufactured for the Embalse Río III Nuclear Power Plant in the province of Córdoba (Argentina).
  • IMPSA was also awarded a contract for the design, manufacture, transportation and erection of the pressure vessel assembly for the Carem 25 Nuclear Reactor, the first Argentine nuclear reactor for power generation.
  • IMPSA’s Wind bay for the production of wind turbines was built on the premises.
  • In January 2017 IMPSA was awarded the rehabilitation –with new hydraulic and mechanical design– of two 154 MW Kaplan turbines and the supply of the runner’s internal tubes for the Yacyretá Hydropower Plant.
  • On April 27, 2018, and as a result of the amendment of its bylaws, the company changed its business name to “IMPSA” (formerly INDUSTRIAS METALÚRGICAS PESCARMONA “IMPSA” SAICF), which marked the beginning of the closing of the debt restructuring process.
