Weather Forecasts, Mesoscale Observations and Climate information are used to make daily operational decisions in the following areas:

Weather Forecasts, Mesoscale Observations and Climate information are used to make daily operational decisions in the following areas:

Load Forecasting that supports daily generation portfolio optimization

Optimization of Hydro Electric Resources

Hourly pricing

Weather Risk Analysis for load obligation

Monthly and seasonal forecasts for fuel inventories

Seasonal Forecasts for revenue projections

Support energy trading and marketing activities in both the regulated and non-regulated generation

Support Emergency Management for Storm Response

Load Forecasting that supports daily generation portfolio optimizationLoad Forecasting that supports daily generation portfolio optimization

Hourly forecasts of temperatures, dew points, wind speed and cloud cover for input into load forecast models

Real-time surface observations

Precipitation projections

Forecasts developed from NCEP models, MOS, and local forecast methods developed internally

6

Optimization of Hydro Electric ResourcesOptimization of Hydro Electric Resources

Twice daily QPF forecasts that are input into our Hydro Management System (1-3 days)

Medium range QPF projections for lake/river management (4 to 7 days)

Real-time QPE for inflow estimates

Seasonal forecasts for longer range planning and resource availability

7

Weather Risk Analysis for load obligationWeather Risk Analysis for load obligation

Daily Weather forecast Scenario development to capture uncertainty and project a range of possible loads out to 3 days

Forecasts of convection, timing and coverage for possible load shedding

Temperature/wind forecasts for transmission line ratings and lake/river temperature thermal restrictions

8

Monthly and seasonal forecasts for fuel inventoriesMonthly and seasonal forecasts for fuel inventories

Monthly/seasonal outlooks for temperature and precipitation are used for predicting coal inventories, gas storage numbers, and hydro availability

Seasonal forecasts of HDD and CDD are used to estimate revenue projections

Future weather forecast needs?Future weather forecast needs?

Implementation of a proposed National Digital Guidance Database (NDGD) which would provide probabilistic forecast information.

Improving Ensemble forecasts for both short and long range models and make them available through NOAA Port.

Improve the Ensemble MOS product past day 3 by removing climatology as a predictor.

Implement an Ensemble QPF forecast

Real-time surface observations are used for the following operational decisions:Real-time surface observations are used for the following operational decisions:

System load management

System load modeling

Resource decisions related to on-going severe weather events

Inflow calculations for hydroelectric operations

Emergency response decisions related to non-routine releases

Future Mesonet Needs?Future Mesonet Needs?

Increased spatial resolution of surface observations

Real-time SFC data available from a national network via NOAA Port every 15 minutes

Atmospheric boundary layer measurements using remote sensing systems for characterizing the PBL in real-time.

Recommendations under the Human Dimension – BASC ReportRecommendations under the Human Dimension – BASC Report

The stakeholders should commission an independent team of social and physical scientists to conduct end-user assessment for selected sectors. The assessment…………………added societal impact and value.

Themes – Weather prediction

and climate modeling

Support new applications in physical, dynamical, and chemical processes in expanding the user base
