Energy Concept in Business Parks
The on-going centralisation of various business areas, including industrial production and services, leads to growing use of so-called industrial or business parks. They are significant consumers of energy, particularly of electricity and heat. Two situations in particular are responsible for the establishment of business parks: the revitalisation of industrial sites that are no longer in operation (because the original industrial plant has been closed down) and new development zones established in order to support the eco- nomic development of a nearby town. What are the best tools to identify and carry out the energy savings potential?
In both of these cases, the energy needs are usually covered solely by individual organisations that are supplied by new electricity and natural gas connections. The existence of a local electricity distribution system is less frequent and common heat distribution is nowadays even rarer. However, sharing of energy infrastructure is the major factor that makes energy supply and services more environmentally and econo- mically favourable.
Such a coordinated approach calls for someone to take the lead, to suggest suitable solutions and to discuss them with other partners. This person might be the owner of the site who leases the premises, however he if often not interested or does not devote his time to the optimisation of energy services in the park. The position of a future energy supplier can also be performed by a company that already generates and distributes energy on the site for its own needs and is able to offer this service to others as well. Such cooperation might be impeded by a lack of trust between neighbours and their reluctance to share the sensitive data necessary for analysing the overall situation and proposed measures. Finally, the energy for the site can be supplied by an external company in the neighbourhood having spare capacity. However, promising solutions may get side-tracked due to reluctance to collaborate
A feasible solution, therefore, might be accepting the role of coordinator by a third party, such as an independent consultant with no particular interests in the park. It should be a company with expertise in energy sector which is not limited to technical measures. The most important thing is to assess and propose solutions that comply with the national policy and thus can get investment and/or operational support.
From the technical point of view, centralised heat and electricity supply within the site is the most promising measure. The main advantage lies in the fact that a modern central source of a sufficient size is highly suitable for efficient installation and operation of combined heat and power (CHP), which would be far more difficult with decentralised heat and electricity generation. Modern hot water distribution systems have acceptable heat losses. Furthermore, a suitable project comprising a CHP source and establishing or extending a system of district heating may obtain an investment subsidy from the Operational Programme Enterprise and Innovation for Competitiveness (OPEIC). A specific call aimed especially at supporting effective district heating systems has been opened at the beginning of 2016.
This issue of our newsletter brings you two good practice examples that have been recently implemented: the modernisation of heat supply in the Sklady Hodonín business park and the heat supply from a biogas plant to the industrial park in Písek.
