§ 135-h. Installation. 1. A utility shall afford each participant in
its home conservation plan the option of installing energy conservation
measures either (a) by performing the work on a "do-it-yourself" basis,
where deemed safe and feasible by the commission, under guidelines set
by the commission for assuring quality and conformance with applicable
criteria; (b) through the use of services provided by the utility
itself, if the utility decides to offer such services provided, however,
that in offering such services, the utility shall contract, through the
use of prevailing competitive bidding processes, with persons, firms and
corporations not owned or operated by such utility for the installation
of energy conservation measures; or, (c) through the use of the services
of a contractor and/or supplier of the customer's choice, whose name
appears on a list of qualified contractors and/or suppliers maintained
and periodically updated by the utility.

2. In implementing paragraph (a) of subdivision one of this section,
the utilities, in consultation with the commission, shall prepare a
"do-it-yourself" manual for the customers it serves, detailing the
materials capable of being used, their manner of effective installation,
and the criteria used in inspection to determine the degree of
effectiveness. With reference to all installations to be made pursuant
to paragraphs (a) and (c) of subdivision one of this section, the
utility shall prepare and maintain a list of qualified and participating
suppliers and contractors in a non-discriminatory manner. The decision
as to which option, supplier, or contractor to use is the choice of the
customer.
