Thanks to Reuniwatt, they can do so at a regional or country scale. With the development of distributed energy generation facilities, many plant owners \u00a0possess a multitude of small installations spread across a possibly large territory. Therefore, in order to ease the monitoring of one\u2019s portfolio, Reuniwatt has developed weather tools for portfolio management.<\/p>\n<\/div><\/div><\/div>
When one possesses a large number of differently-sized installations, it may be complicated and\/or too costly to install ground sensors everywhere. Moreover, data derived from satellite images have proven to be more accurate than ground measurements located beyond 25km from an actual installation.<\/p>\n<\/div><\/div><\/div><\/div><\/div>
Wind and solar data based on satellite images enable to independently certify performance ratio calculations calculated thanks to ground measurements. Indeed, satellite data are a token of independency as they originate from independent service providers. Therefore, they may also be used to settle any argument relating to the quality of ground measurements.<\/p>\n<\/div><\/div><\/div><\/div><\/div>
Wind and solar energy vary with the weather. Consequently, estimating resources in real time on an entire territory enables to match load fluctuations across several regions.<\/p>\n<\/div><\/div><\/div><\/div><\/div><\/div><\/div><\/div>
