“maximum 30 minutes power” means the maximum net power of an electric drive train at DC voltage as set out in paragraph 5.3.2. of UNECE Regulation No 85

“net power” means the power obtained on a test bench at the end of the crankshaft or its equivalent at the corresponding engine or motor speed with the auxiliaries, tested in accordance with Annex XX (Measurements of net engine power, net power and the maximum 30 minutes power of electric drive train), and determined under reference atmospheric conditions;

The net power and the maximum 30 minutes power for electric drive trains indicated by the manufacturer for the type of drive train shall be accepted if it does not differ by more than ± 2 per cent for maximum power and more than ± 4 per cent at the other measurement points on the curve with a tolerance of ± 2 per cent for engine or motor speed, or within the engine or motor speed range (X1 min–1 + 2 per cent) to (X2 min–1 – 2 per cent) (X1 In case of a dual-fuel engine, the net power indicated by the manufacturer shall be the one measured on the dual-fuel mode of that engine.

The electric drive train shall run at the bench at a power which is the best estimate of the manufacturer for the maximum 30 minutes power. The speed must be in a speed range, which the net power is greater than 90 per cent of the maximum power as measured in paragraph 5.3.1.

The application for approval of a drive train type with regard to the measurement of the net power and the maximum 30 minutes power of electric drive trains shall be submitted by the drive train manufacturer, the vehicle manufacturer, or by his duly accredited representative.

However, [30-40 %] of gensets within the 1,5-2 MW power range are sold as part of multiple genset projects, and [30-40 %] of projects within this power range are served with multiple genset bids.
