What PSR does
PSR is a privately held global energy consulting and software firm founded in 1987 in Rio de Janeiro by Mario Veiga Pereira, the originator of the Stochastic Dual Dynamic Programming (SDDP) methodology. The company develops and licenses a suite of proprietary computational models — SDDP, OptGen, NCP, Time Series Lab, HERA, OptFolio, and the PSR Cloud high-performance computing platform — that apply advanced stochastic optimization, mixed-integer programming, and non-linear methods to hydrothermal dispatch, generation and transmission expansion planning, short-term scheduling, renewable scenario generation, hydropower assessment, and energy portfolio optimization. These tools are used in dozens of countries and have supported the design of Brazilian energy procurement auction mechanisms through which 80 GW of new generation capacity has been contracted since 2005.
The firm earns revenue through four streams: software licensing (with a reported 98% renewal rate), professional consulting engagements, contracted R&D projects (including ANEEL-funded R&D and work for World Bank, IDB, GIZ, and UNIDO), and subscription-based analytical publications (Energy Report and Analytics Report). PSR serves electric utilities and system operators, energy investors and developers, government energy agencies, and energy traders and commercializers across 70+ countries on five continents, with approximately 50% of revenue generated outside Brazil. Its leadership includes IEEE Fellows, US National Academy of Engineering members, former presidents of EPE, and technical directors with tenures at PSR ranging from 9 to 27 years.
Operationally, PSR runs a sales-led direct enterprise model supplemented by an annual global user meeting and a content marketing presence via the Energia em Foco hub on Exame magazine. Current strategic activity centers on energy transition themes — energy storage (joint studies with Instituto Clima e Sociedade), green hydrogen (R&D with CPFL Energia), carbon capture in bioelectricity (with Siemens Energy), industrial decarbonization (for UNIDO), and capacity building for Brazilian planning institutions such as EPE — alongside continuous redevelopment of long-running international software engagements such as GENESYS for the Northwest Power & Conservation Council.

PSR competitors and assessment
Company assessmentDirect peers
- Tractebel Engineering (Engie): Tractebel is a global engineering and consulting firm that performs power system planning, energy market studies, and regulatory advisory for utilities and governments. Competes with PSR's consulting arm in generation/transmission planning and energy market design projects across Europe, Latin America, and emerging markets.
- Artelys: Artelys provides mathematical optimization software (Artelys Knitro, Artelys Crystal) and energy consulting for power system planning, unit commitment, and market design. Direct competitor to PSR's optimization-driven approach to hydrothermal and renewable integration challenges.
- DNV (formerly KEMA): DNV's Energy Systems business provides independent power system consulting, market advisory, and testing for utilities, regulators, and developers. Overlaps with PSR's regulatory advisory, market design, and grid modernization consulting work, especially in Europe and the Americas.
- Energy Exemplar: Energy Exemplar develops PLEXOS, the leading energy market simulation and optimization platform used by utilities, regulators, and market operators globally. Direct competitor to PSR's SDDP/OptGen/NCP in production cost modeling, expansion planning, and stochastic optimization for power systems.
Broad incumbents
- Hitachi Energy: Hitachi Energy offers enterprise software (Lumada APM), grid control systems, and energy consulting for utilities and transmission operators. Competes with PSR at the portfolio/broker level as a broad incumbent offering integrated software + services for power and grid customers.
- Siemens Energy: Siemens Energy provides grid software (PSS), power plant equipment, and energy consulting services. Recently partnered with PSR on bioelectricity carbon capture R&D, while also being a potential competitor in grid planning and energy transition advisory for large utilities.
- GE Vernova: GE Vernova (spun off from GE) offers power generation equipment, grid software (GridOS), and energy consulting. As a broad incumbent, it competes in expansion planning, grid optimization, and energy market software – the same enterprise layer where PSR's tools are deployed.
Others
