Abstract: For several years, Northern Indiana Public Service Company received daily weather forecasts over the telephone from a Chicago-area consulting meteorologist firm. The forecasted values of hourly temperatures and wind speeds were used to calculate manually the heatsensitive portion of the estimated natural gas supply needs for the upcoming gas day. When NIPSCOs new gas dispatch SCADA system was installed last year, the telephone dialogue was replaced by a new computerized dial-up data link. The link uses off-the-shelf hardware and custom software, which was developed jointly by personnel at NIPSCO, the meteorologist firm, and the gas dispatch system contractor. Weather data may now be reviewed by gas dispatchers via CRT displays and heat-sensitive load is calculated by a load forecasting program resident in the gas dispatch computer system. The program uses weather forecast data that are transferred directly into the computers memory.
