Clock-changing ritual for the last time… really?

The proposed directive sounds simple to begin with. From 2019 it might be, that Germany will just remain in the summertime and there will be no fuss about adjusting to wintertime or the so-called standard time. Other states have the right to decide differently and switch the clocks back again in autumn 2019 with the prospect of another change into summertime. Apparently, a potential outcome will be even more time zones within the EU and that will eventually lead to massive issues in the energy industry as converting will increase enormously. Though this is already a common practice e.g. when trading with East-Europe or Great Britain, the necessity will become more frequent. Especially some IT-systems, which could ignore the time zone altogether, will now be confronted with additional efforts.

Complexity even increases when dealing with the past or future trades that have been made for hours, which do not longer exist.

Currently base and peak products for the forth quarter can be traded at EPEX. But what will happen with the additional hour in October 2019, which is still existing and can be traded at the moment. Is it indispensable that all deals already made must be corrected because a less amount of energy will be delivered? Anyway, it would be desirable that an explicit procedure is set up to meet these effects on the energy market.

The forecast of energy use and consumption will be concerned by this subject, too. Personally, I will consult the display in my car when I need to know the right time driving to work. Consequently, my consumption behaviour changes accordingly. But it will be different with the energy production of PV-systems. In winter 2019 sun rise will be one hour earlier than in the last years. To ignore effects on the sales and production forecasts would result in exceeding costs for balance energy.

Manufacturers of IT-systems and IT-departments in the energy industry will be facing organizational challenges. All connected systems need to be provided with up-dates in a tight time frame. It is very likely that we will see error messages like “Time series rejected because four values are missing”.

It remains to be seen, whether the abolishment of time change will be realized as fast as it is discussed presently. But the expected expenses for the adjustment of the IT-landscape shouldn’t be underestimated. However, we’ll be happy to receive your comments or different ideas concerning this controversial issue.
