(1) The provisions of Article VIII, § 7 of the Washington Constitution prohibit a city or public utility district from assisting its utility customers, generally, in the purchase of such conservation materials as insulation or storm windows from private suppliers by providing to the seller a guarantee of payment of part or all of the agreed upon purchase price for the conservation materials involved. (2) The same provisions of Article VIII, § 7 of the Washington Constitution, however, do not prohibit a city or public utility district from itself purchasing and then later selling such conservation materials to its customers, generally, by means of installment contracts under which payment of the purchase price, plus a service charge, would be made by the purchasers on a periodic basis over a specified period of time.
