This roadmap defines R&D pathways for ensuring cost-effectiveness, reliability, and safety throughout the life cycle of existing and future generating assets, encompassing design, procurement, commissioning, operations, maintenance, and end of life options across a fleet.

To support asset management and reliability in fossil and renewable energy applications, new knowledge and innovations are being pursued in the following areas:

  • Materials, degradation, inspection, nondestructive evaluation, and remaining life assessment
  • Design, specifications and procurement
  • Operations and component and system health assessment through sensing, monitoring and analytics
  • Maintenance, overhaul, and repair
  • Decision support and integrated process management

EPRI’s comprehensive R&D program will deliver technical tools, advanced technologies and process improvements to help plant managers and workers achieve cost, reliability, and flexibility targets by completing operations, maintenance, and modernization tasks more effectively while managing assets from cradle to grave. Higher-performance materials and components in combination with greater insight into real-time conditions will assist asset managers in allocating resources, implementing best practices, and improving performance across fleets.


Diversity of Generation

Dispatch of many fossil-fueled power plants has changed over the last decade to require increased flexible operation. These new duty cycles entail more frequent unit starts, higher load ramp rates, lower minimum loads, and both more frequent and longer-lasting reserve layups. Each mode of operation affects performance, reliability, and lifetime differently, with varying impacts across components and systems. Damage can accumulate—but go undetected—over many cycles, increasing the risk of failures and forced outages.

Generation Excellence

In addition to increasing equipment wear and tear, flexible operations can degrade efficiency and environmental performance. Meanwhile, pressures to reduce costs and achieve tighter standards continue. Changed mission profiles and competing objectives add new layers of complexity to asset management at the component, system, plant, and fleet levels. Innovations in distributed sensing, automated inspection, materials reliability, and other areas can help meet the challenge of maximizing operational readiness with reduced staffing and maintenance investment.

Power Industry Transformation

As the industry undergoes a rapid evolution, traditional plant performance metrics such as cost, efficiency, productivity, dispatchability, and reliability are taking on new dimensions. This complicates efforts to optimize operational strategies, maintenance budgets, capital investments, and business plans across fleets. Asset managers need state-of-the-art tools for performance analysis and improvement—spanning people, processes, and technologies—across multiple sites, myriad variables, and diverse supply portfolios.


Power producers will apply a holistic asset management perspective to make the operations and maintenance (O&M) decisions and investments required to meet flexible mission profiles, control costs, and lower emissions without compromising competitiveness, reliability, or safety.

Fundamental research through laboratory testing and engineering analysis will provide the foundation needed to understand and manage damage mechanisms affecting existing equipment, as well as to inform the development of higher-performance materials and components and the industry codes and standards required for their commercial application. Technical knowledge and industry experience—encompassing lessons learned, successes and failures, and best practices—will be organized and synthesized to continue enhancing EPRI’s collaborative asset management database, analytical tools, and guidance documents.

At the component, system, unit, site, and fleet levels, power producers will employ decision frameworks, programmatic processes, and enterprise strategies that integrate systematic and comprehensive asset management within core operations, maintenance, engineering, business, and planning functions.

Innovations in sensing, monitoring, data management, analytics, and control—as well as inspection and NDE—will enable fine-tuning of operations, more accurate condition assessment, and real-time management of component and system health. To maximize asset value, continuous process optimization also will encompass early detection of incipient problems, enabling inspection-for-cause and proactive response to avoid life-limiting damage. Cross-functional programs in equipment reliability, root cause analysis, asset monitoring, and other areas will ensure consistent fleet-wide performance.

Design and procurement specifications will reflect basic knowledge and state-of-the-art practice for ensuring quality and reliability. Plant maintenance, overhaul, and repair decision-making will benefit from novel materials and surface protection methods, engineered weld solutions, and advanced components and systems with improved flexing capability and enhanced reliability.


The 5-year Generation Sector program plans address immediate R&D priorities relating to asset management and reliability. This roadmap defines collaborative R&D pathways leading to new knowledge and advanced technology for improving asset management and reliability—both for existing plants and future capacity additions—over a timeframe 5 to 10 years out, and beyond.

Areas of focus are introduced below. Relevant R&D is under way or anticipated across the Generation Sector’s base programs. Also highlighted are ongoing and planned work through EPRI’s Technology Innovation (TI) program.


Improved fundamental understanding of the properties, performance characteristics, and in-service degradation and aging of power plant materials and components is needed as the basis for informed asset management, condition-based maintenance, and increased reliability. Advanced materials, welding and surfacing methods, and manufacturing technologies—approved for use by code and standard bodies—are needed to provide cost-effective solutions for remediating and preventing damage to existing equipment and for deploying new components to increase flexibility, reliability, and asset value.

Ongoing and planned EPRI R&D activities address the following topics:

  • First Principles. Improved understanding of materials properties, operating conditions, individual and interacting damage and aging processes, failure modes and root causes, and other factors influencing component performance and reliability.
