Chief Marketing Officer at the Barbados Light and Power Company, Stephen Worme says the incident occurred north of Codrington Hill, near Whitehall, between the Warrens and Haggatt Hall sub-stations.
The monkey is believed to have tripped a 24 000 and 11,000 volt circuit after it climbed a pole.
Mr. Worme says while they are still trying to find the monkey, they believe that it got the shock of its life.
NO POWER PROBLEMS FOR CWC 2007
The local organising committee for the 2007 World Cup says it is preparing for any eventuality like today's island-wide blackout during its hosting of the super eight or world cup final matches.
World Cup Barbados says just last week it met with senior managers of the Barbados Light and Power Company, who've moved to ensure electrical issues are approached in a wise manner.
World Cup Barbados says while it can't predict the future it's trying to eliminate the possibility of anything bringing down the systems while Barbados hosts the super eight and finals of the premier global cricketing showpiece.
Chief Corporate Communications officer of World Cup Barbados, Francine Charles says Kensington Oval is tied into a two generator system by the Barbados Light and Power Company.
This means that if one generator trips the other automatically kicks in to ensure continuity at the Oval.
Mrs. Charles says if a blackout like today's occurred during Barbados hosting of the tournament, international television coverage won't be compromised.
And Barbados or the other Caribbean won't be embarrassed internationally.
She stated that arrangements have been made for broadcast companies to remain on air during any scenario like today.
Mrs. Charles says the generators provided for the Oval would have kept them going most of the day to ensure that the close to 30 thousand people filling the ground are not inconvenienced by lack of electricity.
In fact just last week World Cup Barbados met with senior managers of Barbados Light and Power to discuss such an eventuality, stressing that the importance of utility companies is critical.
Today while work halted at several places across Barbados because of a lack of electricity, work continued without any stoppages at the world cup construction sites which are powered by generators.
