The power of water
Hydropower provides clean energy, water services, energy security and contributes to economic development. Its role is expected to increase in importance in future power systems, with significant new developments in Africa, China and Latin America. Some of the reasons behind this are an increased global demand for electricity, energy storage, water management and climate change mitigation.
However, the growth of all renewable energy (RE) is dependent on the development of international standards and the verification of compliance to these.
In the case of marine energy, third-party verification to consensus-based standards reduces equipment and project risk, improves safety, performance and reliability, thereby increasing marketplace confidence.
Global system lowers risks and instils confidence
IECRE, the IEC System for the Certification to Standards Relating to Equipment for Use in Renewable Energy Applications, was established to provide services comprising project and device certification for site selection, operational requirements, maintenance and repairs. It also covers the qualification of personnel for the wind, solar and marine sectors.
“If an industry can collectively establish technical standards and certification processes through global consensus, international markets will be able to evaluate technology viability fairly, more efficiently. This will eventually lead to the positive adoption of marine energy technologies worldwide”, said Sandy Butterfield, IECRE Chair.
Assessing the global potential of hydropower
Attending Hydrovision, the largest worldwide gathering of hydro professionals, in Colorado, US, in June, Butterfield participated in the panel session Current challenges for the marine and hydrokinetic energy (MHK) industry, aimed at identifying and discussing the challenges for this industry, with the goal of providing data and narrative for use when presenting to potential investors.
In particular, he highlighted the fact that for tidal and wave energy equipment, testing alone was not sufficient for verifying design. Instead, design evaluation, requires checking extreme load cases and fatigue life verification, which are provided within the IECRE System.
The event covered a broad range of issues including:
- Asset resilience and sustainability (strategy, business plans, technology and tools, training and education)
- MHK (challenges, regulatory process, benefits of traditional hydro to MHK)
- Operations and maintenance (inspection technology, planned outages, data capturing tools)
- Regulations and policy (US and international changes in climate policy)
- Civil works and dams (managing risk, remote technology for diagnosing and monitoring safety issues)
- New developments (impact of technology, power purchase agreements, interconnection and transmission, global case studies, future projects)
- Water and environment (optimizing water use in multipurpose systems, creating environmental benefits with hydro)
IECRE marine sector
IECRE aims to facilitate international trade in equipment and services for use in RE in the marine, solar PV and wind energy sectors, while maintaining the required level of safety.
IEC Technical Committee (TC) 114: Marine energy - Wave, tidal and other water current converters, prepares International Standards the IECRE System uses to assess marine energy systems. The Standards cover aspects, such as measurements of mechanical loads, guidance for design and analysis of an ocean thermal energy conversion (OTEC) plant, electrical power quality requirements and power performance assessment, for wave, tidal and other water current converters.
