This part of IEC 62600 provides:

  • A systematic methodology for evaluating the power performance of river current energy converters (RECs) that produce electricity for utility scale and localized grids;

  • A definition of river energy converter rated capacity and rated water speed;

  • A metho dology for the production of power curves for the river energy converters in consideration; and

  • A framework for the reporting of results.

Exclusions from the scope of this document are as follows:

  • RECs that provide forms of energy other than electrical energy unless the other form is an intermediary step that is converted into electricity by the river energy converter;

  • Resource assessment, that will be addressed separately in the River Energy Resource Assessment Technical Specification;

  • Scaling of any measured or derived results;

  • Power quality issues;

  • Any type of performance other than power and energy performance; and

  • The combined effect of multiple river energy converter arrays.
