THERE was a reasonably favourable City reaction to the National Grid move across the pond to the comforting confines of New England which is geographically and culturally as near as it could get.

And the shares eased modestly as there are the inevitable fears that it is taking on something new.

However, the exposure is not that substantial given the #2.7bn value of the stake in the Energis telecoms business which will be able to capitalise on New England Electric System's own aspirations in that particular utility sector.

National Grid currently has no intention of selling its 74% Energis stake for another three to five years but that could alter if a really major opportunity did suddenly come its way.

There was a slight sense of frustration that chief executive David Jones would say little about the cost-cutting benefits - probably for political reasons ahead of regulatory approval.

There was also some puzzlement as to why he is not buying an inefficient operator in the same way that ScottishPower is acquiring PacifiCorp where there is a substantial inbuilt profit to come in due course from raising efficiencies before having to worry about price mechanisms.

Tomorrow, ScottishPower will give a lecture to the City on US regulatory and utility pricing which should assuage doubts about both its own deal and also help National Grid.

It is also likely to be attended by representatives of both British Energy and PowerGen which are also looking hungrily at the US as the world's largest energy market.

The question for both Scottish Power and National Grid is whether their negotiating skills and UK experience are really transferable and it will take a couple of years before the picture really becomes clear. But if they cannot make a go of it in the US, then their prospects elsewhere must be limited.

Electrical utilities in the UK have approximately trebled in value since privatisation and National Grid was downplaying the potential of its NEES acquisition on that score.

But it is a cautious company and on present information, shareholders should give it full support.
