Examples of context:
"Eine Tagesbelastungskurve mit m = 0,7 bezeichnet man als EVU-Last."
"Spezifischer Bodenwiderstand (z.B. ausgetrockneter Boden < 1 K ⋅ m/W) und Belastungsgrad m (z.B. Dauerlast bzw. EVU-Last) bei Kabelverlegung in Erde"
"Die sogenannte EVU-Last, in Abbildung 59 dargestellt, bezeichnet einen charakteristischen Belastungsverlauf innerhalb eines Tages mit einem mittleren Belastungsgrad von m = 0,73 p.u."
"Für den Normalbetrieb wird üblicherweise die sogenannte EVU-Last mit dem Faktor 0,7 angesetzt."
"Belastungsgrad 0.7 (EVU-Last)"
This is evidently related to the load factor and I can find plenty of examples of usage of this acronym, but no definition of what it stands for, and in several references it is either left in German or omitted entirely, e.g. https://www.nexans.com/Germany/files/Starkstrom_D_GB_mrz04.p...
* Sentence or paragraph where the term occurs: See above
* Document type: EMC assessment

adjusted /standardised load (factor)
Where 'factor' would be optional.
The figure arrived at (0.7 - or 70%) seems to be a German standard used in the mathematical sizing of power cables, where the adjusted value represents 70% of the actual load factor.

Anmerkung: Für die Kabelauslegung wird eine EVU-Last
(m = 0,7) auf Grundlage eines Tageslastspiels
angenommen
Note: For the dimensioning of cable, a load factor of 0,7
is used based on a daily load cycle

--------------------------------------------------
For the sake of completeness:
The EVU element likely (?) suggests an industry-agreed standard that load factor should be calculated here at 70% of its nominal value to better reflect the day-to-day variations in the load itself.
Hence the offering of 'standardised', as well as 'adjusted', to which we might also add 'revised' as a further alternative.

Adding to Alison's references:
I've also seen the term offered as "load grade" in one or two locations, but didn't think that this conveyed any reasoning behind the adjustment:
"...ground temperature 20°C, EVU load grade 0,7..."

"

It likely does stand for 'Energieversorgungsunternehmen', but, as mentioned, not at all the contextual setting for inclusion here.
My answer is based on a more descriptive sense of the term, but could easily be replaced by 'EVU load factor' (definitely without translating its origins).
These are the only two options I would feel content with for final submission.

Note from asker:
| Yes, seems legit, but what does EVU stand for here and is it really EVU in English, too (if not left out, as frequently seen in the online references? |

: "energy" ist eine Arbeit, gemessen in kWh, "load" ist eine Leistung, gemessen in kW. Beides passt nicht zusammen in einen Begriff. Da es um die schwankende Last geht, muss "energy" entfallen.

utility load factor or utility's load factor
Die EVU-Last hat zwei Aspekte, einerseits ist es die mittlere abgenommene Leistung durch die Verbraucher, und zum anderen die dadurch hervorgerufene mittlere Belastung der stromerzeugenden EVU-Generatoren.
In electrical engineering the load factor is defined as the average load divided by the peak load in a specified time period.[1] It is a measure of the utilization rate, or efficiency of electrical energy usage; a high load factor indicates that load is using the electric system more efficiently, whereas consumers or generators that underutilize the electric distribution will have a low load factor.
https://en.m.wikipedia.org/wiki/Load_factor_(electrical)
Load Factor
A utility's load factor is its average load as a percentage of its peak load. Think of it in terms of an airplane flying without all of its seats full. If the utility distributes power to a dedicated transformer at a customer's facility which has a 100-seat capacity and can fly 365 days a year, but only has 50 percent of its seats full, the customer's load factor is 50 percent.

Abstract: Demand response (DR) is coming into consideration day by day as it can very well avoid system stress conditions through proper load management. DR can avoid building new large-scale power generation and transmission infrastructures by improving the electric utility load factor.

Utility load factor is a utility’s average load as a percentage of its peak load. In other words, it is the amount of available power-generation assets being utilized on a yearly basis.

Sein Belastungsgrad und sein Lastverhältnis betragen m = 0, 7 und m0 = 0,508 (5.6.1)
Diese Parameter hat man bisher als typisch für ein Energieversorgungsunternehmen angesehen und bezeichnet einen solchen Belastungsgang daher oft als EVU-Last.
https://webcache.googleusercontent.com/search?q=cache:A1UZr6...
Bei Elektroenergiekabeln ist der zulässige Strom IZ maßgeblich. Randbedingungen sind hierbei die sogenannte EVU-Last, ein spezifischer Erdbodenwärmewiderstand von 1 Km/W, eine Erdbodentemperatur von 20 °C und eine Verlegung in 0,7 m bis 1,2 m Tiefe (vgl. Kap.5.3.3). Der EVU-Last liegt ein Belastungsprofil zu Grunde, wie es in den Netzen der Energieversorgungsunternehmen (ehemals EVU, heute Netzbetreiber) üblich ist. Für abweichende Verlegebedingungen und Belastungsarten ist der Bemessungsstrom entsprechend zu korrigieren [ABB-99].

"This is evidently related to the load factor..."

if you feel this might be right, I delete my previous answer and submit a new one.
And apropos:
