“…In addition, low-temperature heat can be used in an efficient energy system, improving the environmental performance of the industry. Apart from the reduced climatic impact, the lower distribution temperatures will also enable and improve the utilization of renewables and excess heat sources in general [15].…”

This paper addresses the implications on the business model of district heating companies of the technology shift targeting lower temperatures in the distribution network. Lower temperatures are valuable, since heat supply to low-energy buildings with low grid losses is facilitated. In addition, low-temperature heat sources can be integrated into an efficient energy system, improving the environmental performance of the industry. This technology shift opens a window of opportunity to update the business logic in the sector, since the lower temperatures allow a diversification of the value proposed to customers and a closer, long-term customer relationship. The extent to which the business model is impacted by the shift is not known. Thus, six cases of low temperature implementation from five European countries have been identified. Interviews with the project managers of the implementations show that the six cases made limited change to the primary business model when making the technological shift. Consequently, there is an unexplored potential for updating the value proposition and the customer relationship.

“…Recent research relating to district heating have mostly focused on alternative energy sources and technologies, such as waste heat [33,34], solar heat [35], biomass [36][37][38], heat pumps [39][40][41] and natural gas [42]. In order to handle the low energy efficiency and pollutant issues of coal-fired district heating, a low temperature air source heat pump was proposed as offering a more effective heating system to coal-fired district heating, to be used in Beijing [43].…”

Although district heating is an energy-effective solution for cold countries, the coal-fired district heating sector is still facing significant challenges as regards sustainable development, during its operational stage. In order to achieve better operational performance, public private partnerships (PPP) have been introduced in relation to managing clean coal district heating, as a value for money (VfM) solution. To date, however, studies of the application of clean coal in district heating operations are rare and the lack of an evaluation framework hinders the effectiveness test on this sustainable solution. This research aims to investigate the effectiveness of PPP as a VfM solution to the operation of clean coal district heating, by developing an assessment framework on the basis of three dimensions of sustainability: economic, social and environmental, and discussing the proposal, by means of a case study. The assessment results show that the PPP operation offers good VfM performance but with room for improvement, including more user engagement. This research contributes to the literature on clean coal district heating and PPP by providing a comprehensive assessment framework for evaluating VfM performance of the concept. The application of the framework can help the authorities with a robust PPP assessment and thus, improve the sustainable performance of the clean coal heating operation.

“…Both of the aforementioned studies show that SCs paired with TES are a viable solution for reducing emissions in DH systems with a fossil fuel-based heat supply. Rämä and Mohammadi [40] compared distributed and centralized SCs with the same total investment in a small-scale DH system, concluding that a centralized SC plant connected to DH outperforms the distributed systems.…”
