If the plant has, say, an oil unit that provides startup power for something else that uses some other fuel, then the net generation from oil would be negative. I think that's where some of the negative numbers come from.<BR/><BR/>But in general, yes, eGRID has a lot of outlier data. The eGRID docs say that these exist in the databases that they use to make eGRID. I haven't yet had time to dig into them and track them back to where they came from. You may want to contact the eGRID people about particular ones. It does point out that as we get more serious about global warming concerns, we're going to need a better database, not one patched together out of a number of legacy databases none of which were designed for that purpose.Rich Puchalskyhttps://www.blogger.com/profile/13565210317964576866noreply@blogger.comtag:blogger.com,1999:blog-1991402668327441142.post-51487754367224582632008-12-23T11:58:00.000-08:002008-12-23T11:58:00.000-08:00Hi Rich,I have been playing with Egrid for a coupl...Hi Rich,<BR/><BR/>I have been playing with Egrid for a couple of weeks now and I would be interested to know if you have an opinion on the outliers within the database. There are plants with negative heat rates, negative generation, and other bizarre artifacts. Makes me question the overall quality of the dataset. <BR/><BR/>BenIrksomehttps://www.blogger.com/profile/00025918123893259818noreply@blogger.com
