5. Paragraphs 3 and 4 do not apply to an installation, except an installation which forms part of a district cooling network, with any of the following—
(a)available waste heat of 100 kilowatts or less;
(b)available waste heat—
(i)greater than 100 kilowatts as hot water or steam, where there is no hot water heat demand greater than 100 kilowatts within the search radius from the installation as set out in the table below, and located within the connection distance from the centre of the installation, or
(ii)greater than 500 kilowatts as steam where there is no steam-based heat demand greater than 500 kilowatts and no hot water heat demand greater than 100 kilowatts within the search radius from the centre of the source installation as set out in the table below, and located within the connection distance from the centre of the source installation;
(c)a heat demand of—
(i)100 kilowatts or less for a hot water heat demand, or
(ii)500 kilowatts or less for a steam-based heat demand;
(d)a hot water heat demand greater than 100 kilowatts, with no source of available waste heat greater than 100 kilowatts within the search radius from the centre of the demand installation as set out in the table below, and located within the connection distance from the centre of the demand installation;
(e)a steam-based heat demand greater than 500 kilowatts, with no source of steam-based waste heat greater than 500 kilowatts within the search radius from the centre of the installation as set out in the table below, and located within the connection distance from the centre of the demand installation.
| Installation type | Thermal capacity of heat source/demand | Search radius (kilometres), measured from the centre of the installation |
|---|---|---|
| Hot water demand | >100 kilowatts and <3.9 megawatts | 0.0038 x H, where H = thermal capacity in kilowatts |
| ≥ 3.9 megawatts | 15 | |
| Steam demand | >500 kilowatts and <12.5 megawatts | 0.0012 x H, where H = thermal capacity in kilowatts |
| ≥ 12.5 megawatts | 15 | |
| Waste heat source (hot water or steam) | >100 kilowatts and <3.9 megawatts | 0.0038 x H, where H = thermal capacity in kilowatts |
| ≥ 3.9 megawatts | 15 |
