0421: CPF: Integration of Radar & Satellite Participation Estimates into Rain and Snow Gauge Networks

Rain and snow measurements are usually performed using ground-based gauge networkobservations. However, for remote regions, gauge measurement is limited. In the past few decades,with the availability of improved measurement systems such as radar measurements, satelliteestimates, and numerical weather prediction output, precipitation observation for regions wheregauge network data is not sufficient has been largely improved.Numerous data integration systems have been developed to combine the diff

0408: Assessment of Inflow Forecasting Tools

In today’s competitive energy market, water managers need optimized strategies for maximizing the profitability of their hydropower systems. Accurate and reliable inflow forecasting tools are critical for hydropower operators to balance competing interests and make informed operational decisions leading to efficient use of water resources. Over the past decades, a large number of inflow forecasting tools have been developed with varying degrees of complexity, accuracy and performance, depe

0430: CPF: Roadmap for Applied Statistical Analysis Techniques for Hydro Generation and Runoff

Hydropower operators are busy with day-to-day operations. They need to an actionable tool that guides them to appropriate statistical methods to process the vast amounts of data related to inflow forecasts and runoff determination. CEATI previously published two reports (CEATI Report No. T132700-0425 Review of Data Screening Methods for Discharge/Inflow Time Series and CEATI Report No. T152700-0426 Applied Statistical Analysis Techniques for Hydro Generation and Runoff) that provide operators wi

0432: CPF: Review and Recommendation of Hydrologic Forecast Verification Strategies and Methods

This report has two parts. The first contains the review component of the “Review and Recommendation of Hydrologic Forecast Verification Strategies and Methods” project. The objective is to review available and emerging verification techniques, metrics, frameworks, software tools, and systems (both pre-operational and operational) in order to establish guidance and best practices for hydrologic forecast verification. Included is a review of verification theory, verification metrics,

0424: CPF: Outage Planning Maturity Matrix - Methods & Processes for Minimizing Monetary Impacts from Outages

Electricity companies must rely on a high level of availability of their various assets in order to meet their clients’ needs in an ever changing marketplace. In order to achieve this objective, these assets must be kept in a reliable condition, thus requiring outages to perform recurrent annual maintenance, multiannual major overhauls and refurbishments. In addition to the planned outages that are required, forced (or unplanned) outages will unfortunately happen as a result of unforeseen

0412: CPF: Hydrometric Gauging: Standards and Practices

This report presents a review of hydrometric gauging practices as documented in international standards and the procedural manuals of national gauging agencies and as carried out by hydroelectric utilities. The scope covers the measurement of water levels of rivers, lakes, and reservoirs, of river flow and of temperature and precipitation. The agencies covered are mainly North American, but European agencies are also addressed.The relevant standards documents of the ISO, WMO, ASTM and others are

0428: Niagara and St. Lawrence Rivers Ice Study

Volume I: Niagara River Ice StudyIce in the Niagara River reduces New York Power Authority’s (NYPA) and Ontario Power Generation’s (OPG) hydro generation at the Robert Moses and Sir Adam Beck power plants during most years. Continuous efforts have been made to safely control/manage the ice and reduce its impact on power generation. While ice control measures have reduced the hydropower losses, there may be opportunities for improvement.The objective of this report is to review the ic

0425: CPF: Review of Data Screening Methods for Discharge/Inflow Time Series

Accurate streamflow and discharge/inflow data are critical to water resources professionals, as hydrologists, engineers, and hydropower managers rely on these data for their analyses and decision making. However, streamflow and discharge/inflow data are generally measured indirectly and are subject to multiple types of errors, which can have significant impacts on engineering decisions and consequently, public safety.Robust data screening techniques are required to identify and correct streamflo

0416: CPF: Benchmarking Performance Optimization

This study comprised a survey of current utility practices in relation to the characterization of generating unit performance, as well as the development of an associated Best Practice.The survey was sent to 39 hydro-generating utilities. The main information requested in these surveys included high-level system information, methods used by the utilities in defining the performance characteristics of their generating units, and how they make use of this information. In addition, the methods used
