  We analyzed intense geomagnetically induced currents (GICs) recorded during a
complex space weather event observed on 23-24 April 2023. Two geomagnetic
storms characterized by SYM/H intensities of -179 nT and -233 nT was caused by
southward IMG Bz of -25 nT in the sheath fields and -33 nT in the magnetic
cloud (MC) fields. GIC observations were divided into two local time sectors:
nighttime (1700-2400 UT on 23 April) GICs observed during the interplanetary
sheath magnetic storm, and morning sector (0200-0700 UT on 24 April) GICs
observed during the MC magnetic storm. By using the direct measurements if GIC
on several substations of Karelian-Kola power line (located in the north-west
portion of Russia) and gas pipeline station near M\"ants\"al\"a (south of
Finland), we managed to trace the meridional profile of GIC increase at
different latitudes. It was shown that the night sector GIC intensification
(~18-42 A) occurred in accordance with poleward expansion of the westward
electrojet during substorm. On the other hand, the intense morning sector GICs
(~12-46 A) were caused by Ps6 magnetic pulsations. In addition to the Ps6
pulsations, comparable in intensity morning GIC (~44 A) was associated with a
local substorm-like disturbance caused by a high density solar wind structure,
pissibly a coronal loop portion of an ICME.
