About Juan

I help energy, renewables, and infrastructure companies improve their operational profitability through transformation projects, service supply chains, O&M, asset management, aftermarket, and performance improvement.

I work as an independent senior consultant with utilities, IPPs, OEMs, ISPs, infrastructure funds, consulting firms, and industrial companies that need an external perspective to identify opportunities, prioritize initiatives, and turn them into concrete plans with an impact on costs, availability, inventory, service, EBITDA, and cash.

I bring over 15 years of experience in energy, industry, and services, including international leadership positions at GE Vernova / GE Renewable Energy within the Wind business. I have led teams, operations, supply chains, logistics, spare parts, contracts, commercial transformation, and improvement projects in complex, international, and results-oriented environments.

Main Services:

  • Operational diagnosis for energy, renewables, and infrastructure.
  • Optimization of service supply chains, spare parts, inventory, warehouses, and logistics.
  • Review of O&M, asset management, costs, contracts, and performance.
  • Performance, organization, and operating model benchmarking.
  • Operational/commercial due diligence in energy and infrastructure.
  • EBITDA/cash improvement roadmaps.
  • Aftermarket strategy, industrial services, spare parts, and repairs.
  • Expert support for consulting firms, funds, utilities, IPPs, OEMs, and ISPs.

My value proposition lies in connecting strategic vision with operational reality: identifying where value lies, prioritizing the levers with the greatest impact, and translating them into practical actions that teams can execute.
