b'The Sale of Electricity by Local Authorities (England and Wales) Regulations 2010 (SI 2010/1910) provides an exemption to the restriction on local government selling electricity under section 11(3) in the following circumstances. A local authority shall be entitled to sell electricity produced from the following sources: (a)wind; (b)solar; (c)aerothermal; (d)geothermal; (e)hydrothermal and ocean energy; (f)hydropower; (g)biomass; (h)landfill gas; (i)sewage treatment plant gas; and (j)biogases. Under section 33 of the 1976 Act, a district council, London borough or the Common Council of the City of London (and a county or county borough council in Wales (pursuant to SI 1996/3071)) may in certain circumstances make arrangements to restore the supply of water, gas or electricity to dwellings which have been cut off or which are likely to be cut off in consequence of a failure to pay sums due. Where, under such arrangements, a council makes a payment in respect of the supply, the council can demand and recover from the person who is liable to pay such charges a sum equal to the payment together with interest at such reasonable rates as the council may determine. Section 38 of the 1976 Act is a most useful power in that it enables local authorities to enter into agreements with other persons (any public or private person or body) to make full use of the local authorities computers, or services provided by means of a computer, on such terms as the parties consider appropriate. The authority has a duty in settling the terms of such an agreement to ensure that they are terms on which the authority considers that a person other than a local authority could reasonably be expected to provide the facilities or services in question. This suggests the agreement must be on a commercial basis. Authorities should, of course, make sure there are safeguards in relation to confidential information and comply with obligations under the Data Protection Act 1984. In view of the large investment in IT equipment in authorities up and down the country, this provision enables authorities to generate income from equipment in order to obtain value for money and fully utilise this expensive resource. Section 19 of the 1976 Act is a very widely drafted leisure services power giving authorities discretionary powers to charge for a number of differing activities and facilities. The section is covered in more detail in Chapter 13 on Leisure and Community Services. 104'
