The winger made her return from a thigh issue in Wednesday's 2-0 victory away to Liverpool in the Continental Cup.
Coming off the bench midway through the second 45, Hemp made an instant impact by providing an assist from Mary Fowler on Merseyside.
It was our number 11's first competitive action since a 3-0 triumph at Reading in early November.
Taylor revealed in his pre-match press conference that Hemp was in 'a good place' ahead of the Derby, and her return to the starting lineup will provide a major boost against an in-form United side.
With the games coming thick and fast, Yui Hasegawa and Deyna Castellanos are the only survivors from our midweek victory at Prenton Park.
City XI: Roebuck, Casparij, Aleixandri, Greenwood (C), Ouahabi, Hasegawa, Castellanos, Coombs, Kelly, Shaw, Hemp.
Subs: MacIver, Stokes, Houghton, Fowler, Angeldahl, Raso, Morgan, Kennedy, Blakstad.
City will start in our usual 4-3-3 formation, mirroring the lineup used across our different teams at all age groups.
Ellie Roebuck's goal is shielded by a back four of Kerstin Casparij, Laia Aleixandri, Alex Greenwood and Leila Ouahabi.
Yui Hasegawa will sit at the base of the midfield three, with Deyna Castellanos and Laura Coombs provided with licence to get forward.
At the sharp end, Chloe Kelly and Lauren Hemp will provide width for Khadija 'Bunny' Shaw.
