According to E.on the aim of the meeting is to inform local business of any supply opportunities surrounding the construction and operation of the wind farm. It will be held at the Amex Stadium, Brighton on 26 February.
E.on said it was particularly interested in hearing from civil engineering companies and marine contractors.
Companies looking to supply the project will have their details passed on to (yet to be appointed) tier 1 contractors. It is targeting companies in East Sussex, West Sussex, Kent, Surrey and Hampshire.
The UK has the largest offshore capacity in the world. However, there has been a lot of critism about the high number of contracts that have gone to foreign companies.
In October, E.on faced questions from the GMB, the union for UK energy sector workers, about the job creation potential behind Rampion.
The GMB said it was concerned that the wind farm destined for the Brighton seaside will bring no benefit to the south coast economy.
GMB national secretary for energy, Gary Smith, said "The GMB wants the facts from E.on as we suspect that the turbines will be sourced in Germany or Denmark. Where is the up side for the UK economy if the turbines are made on the continent, brought over on Dutch barges and connected with cables manufactured in China?"
