88.—(1) The revocation or variation pursuant to regulation 86(3), (5) or (6) of a consent under the Electricity Act 1989 or a direction deeming planning permission to be granted takes effect upon the service of the notices required by regulation 87(1) or, where there is more than one such notice and those notices are served at different times, upon the service of the last such notice to be served.
(2) Where the competent authority decide not to proceed with the revocation or variation, the consent or direction has effect again as from the time of that decision, and thereafter has effect as if—
(a)any period specified in the consent or direction for the taking of any action, being a period which had not expired prior to the date mentioned in paragraph (1), were extended by a period equal to that during which the revocation or variation had effect; and
(b)there were substituted for any date specified in the consent or direction as being a date by which any action should be taken (“the specified date”), not being a date falling prior to the date mentioned in paragraph (1), such later date as postpones the specified date by a period equal to that during which the revocation or variation had effect.
(3) The revocation or variation of a consent or direction as mentioned in paragraph (1) does not affect anything done under the consent or direction prior to the revocation or variation taking effect.
