Plans are being negotiated to provide free heat from a straw fired power station, currently under construction on the outskirts of Sleaford.
Eco2 Lincs, which is building the 40MW power plant off Boston Road, is already progressing with the first phase to provide a district heating system to Sleaford Football Club, Sleaford Bowls Club and Sleaford Leisure Centre.
But negotiations are still ongoing for the second phase, which would see the waste heat piped under the River Slea to serve North Kesteven District Council offices and the William Alvey primary school.
NK Executive Board members have agreed to put back the expiry date of the Wellbeing Agreement drawn up with Eco2 Lincs by a year to enable planning permission for the second phase to be completed.
Discussions have been held with the Sleaford Navigation Trust and the Environment Agency on the way the pipes will be positioned.
The provision of heat from the power station will provide a maximum peak thermal load of 1.8 megawatts, enough to heat all five sites.
* Eco2 Lincs are also joining forces with contractors RG Carters to offer an apprenticeship scheme for two people looking to get into the construction industry. For more information, log on to www.n-kesteven.gov.uk/slcr.
