The Varmelast unit handles load dispatching of the heat production in the greater Copenhagen area. Varmelast is manned by a total of five employees from the three heating companies.
The Varmelast unit always make the day-ahead planning, whereas the intraday heat plans in the evening and at night are usually made by the heating companies’ control room (manned 24 hours) based on the modelling tools of the Varmelast unit. The employees of Varmelast can be contacted by way of an on-duty schedule as required.
The control rooms of VEKS and CTR have the final responsibility for the reliability of heat supply to all customers and can turn on the peak load units in critical situations.
The overall responsibility for the Varmelast cooperation lies with a steering group consisting of senior staff members from the three heating companies. The steering group makes all decisions relating to the operation of Varmelast, e.g. with regard to changes, manning, budgets, purchasing and analysis projects. The chairmanship of the steering group is handled in turns by the three heating companies.
The agreement about the load dispatching of the heat production is handled and determined in the Joint Committee. VEKS, CTR and HOFOR Fjernvarme have jointly entered into the Load Dispatching Agreement with the owners of the large CHP plants HOFOR Energiproduktion and Ørsted. The members of the Joint Committee are Varmelast’s steering group and representatives from the heat producers. Besides HOFOR Energiproduktion and Ørsted, Køge CHP Plant, which is owned by VEKS, and the waste-to-energy companies ARC, Vestforbrænding and ARGO also sit on the Joint Committee.
Currently, an update of the Load Dispatching Agreement is prepared for the purpose of scheduling the heat production in the Copenhagen metropolitan area. An agreement has been made to the effect that the waste-to-energy companies will also adhere to this agreement.
A back-office group has been established to support Varmelast in connection with development and changes in the heating system. The back-office group functions as the daily connection between Varmelast and the heating companies where a number of employees from the three heating companies take part in the back-office work. The back-office members also communicate expected future changes relating to the district heating system and at the plants to Varmelast, so that Varmelast can prepare the dispatching models to be able to handle these. Moreover, back-office assists with the development of the Varmelast function and contributes to analyses and large tasks to be solved in Varmelast.
The operating group is Varmelast’s contact with heat producers. The group is primarily used by Varmelast to gain clarification in connection with questions and incidents in the everyday work.
