Data centers are consuming increasing amounts of energy. They consumed 416 TWh (or about 3% of the total global electricity production) in the year 2015¹. This consumption is expected to double every four years.

Merchant bid
1 Announcements by the investing companies and IEA report ”Renewable Energy Medium-Term Market Report 2015” for US, Brazil, South Africa, Australia and Jordan. All values are reported in nominal euros.United States values calculated excluding tax credits. Typical contract lengths are 15-25 years. The prices indicate levels with which investors have been willing to invest, however, they may not describe the actual comparable costs as the bid prices may be reduced by preferential land prices, site exploration cost, targeted low-cost loans etc. For Sweden the price level at which investors can hedge their renewable production for the next 4 years: average of 2017-2020 electricity (LUL) + elcertificate futures with 29.8.2016 closing prices. Newest Abu Dhabi bids were 21,6 €/MWh but the producers get 1.6 times the payment during June-September and thus the actual average is 27 €/MWh. German offshore tender zero subsidy bids are fully merchant but exclude grid and development costs.

Key energy related features
Excess heat from data centers can fed to district heating / cooling systems and used to provide heat to homes This creates value for the society and the data center operator

UPS as a Reserve
Modern UPS has capabilities to flexibly manage power between different sources: This opens new possibilities for energy management and demand response with additional earnigns

Eaton 93PM as part of SvK pilot. Operating as frequency containment reserve for distrubance (FCR-D). Response to grid frequency with autonomous regulation, activation frequency set to 49,90 Hz.
”Svenska kraftnät anser att resultatet från testperiod 2, då UPS-systemet använde lokal styrning, möter kraven väl och visar att UPS-system har stor potential att delta som resurs på svenska FCR-D-

korrekt på såväl stora som små frekvensavvikelser.”

~ 40 % savings in energy costs EXAMPLE
Datacenters should be closely integrated to energy systems, where they could play a significant role This will benefit the society, but also the data center
