Wrong units used on Power Move Flex email?

My personal achievement of power shifted is expressed in the right units: kWh. Why is the overall shift for last month expressed as a rate  -  “97 megawatts of electricity was shifted”?

HI Bob,

   I’m afraid that most people aren’t scientists and confuse kWh and kW.   Luckily you can (usually) work out which they mean from the context!!!

 

      Rgds,

PS.  I wish OVO hadn’t decided to report electrical usage in half hourly intervals, but used hourly ones, then their usage graphs would be much easier to read/use, and compare with the smart meter current usage rate (measured in watts).

Both Kilowatts (kWh) and Megawatts (mWh) are units of the metric system. Kilowatts are 1000 watts and megawatts are 1000 kilowatts. Gigawatts which will be reached on the grid overall are 1000 megawatts. The kWh means kilowatt hours, so the number of kilowatts used in an hour.

It’s not only the units that are wrong. There were 97 of them, so the verb should be in the plural (were, not was).

Some poor junior member of staff will no doubt be getting a black mark.

Every 1000 kilowatts is equal to 1 megawatt. In general, it has been shown that many people struggle with reading large numbers. So expressing 97000 kilowatts as 97 megawatts is easier to read.

I don’t think I phrased the question well. My point is: kWh is a *quantity* of electricity. mW is a *rate* of  consumption (or production).

Thanks, Steve. That’s my point exactly. But should an energy company be making this mistake?

Hey ​@Bendog ​@BobR ​@MGSteve 

 

Thanks for flagging this, I raised it to the Power Move Flex team, they’ve confirmed that there was a mistake with the unit and it should have been MWh - not MW. 

 

They thank you all for flagging the mistake and that it was an issue in the process. Apologies for the confusion caused here.
