** Morgan Stanley sees energy security as one of three mega themes benefiting European utilities, besides AI and energy transition

** It names three main areas of opportunity to play the energy security angle: faster electrification, renewables capacity extension and grid investments

** MS adds Denmark's Orsted to its top picks alongside National Grid NG.L and Engie ENGIE.PA

** It ups Orsted to "overweight" from "equal weight," and lifts its price target to DKK 225 ($35.27), seeing around 38% upside

** "Whilst Orsted is +33% YTD ... we still see valuation as undemanding with clear steps to achieving a higher SOTP value, unlike much of sector," it says

** The brokerage sees strong upside from lower risk on U.S. projects, solid growth and offshore wind-driven energy security demand ahead of the Danish utility
