Heat supply contracts
Pursuant to the agreements usually concluded for long terms, Veolia selects the appropriate primary sources of energy and ensures that they are used in the most cost efficient manner; it operates and maintains with maximum efficiency all heating and cooling systems taken over for management; it employs and manages its own staff required to supervise facilities; and it also ensures that the systems operated by it remain in an almost new condition by providing repair services which are in most cases part of the warranty provided by Veolia. In addition to all the above, it performs the measurements, tests and settings required by the applicable regulations with particular view to environment related regulations.
In recent years outsourcing facility management related services has become a trend both in the private and public sector. Facility management services mainly constitute the subject matter of agreements relating to office buildings that are sometimes part of institutions finance from the state budget. The content of these agreements are always tailored to the needs of the contracting partner. Agreements may even cover certain basic activities, like the maintenance and management of building engineering systems (heating and AC systems) and buildings, as well as conservation, while services may also include building management, security services, the supervision of the telephone system, reception services, cleaning services, gardening services, internal-external transportation. The idea and the biggest advantage of the whole scheme is that the client enters into a contractual relationship with only one company for the purposes of managing activities defined and considered by it to be secondary.
Veolia’s aim is to apply the most state-of-art technical solutions in all of its contracts. Cogeneration means the simultaneous, combined generation of cooling, heat and power that provides a flexible way to meet customer demand. Cogeneration or trigeneration helps managed facilities achieve their maximum economic efficiency by using gas engines, gas turbines or absorption refrigerators. As a result of heat and power being cogenerated the process is operated with high efficiency and at low costs, although scaling properly adjusted to system requirements is of great importance. Veolia Energia applies the cogeneration solutions in three power plants and it operates 36 gas engines nationwide.
VPP (Virtual Power Plant)
The energetics branch of the Hungarian Veolia has its own virtual power plant that the company started to develop in 2008. Through central control the Telecommunications Control System (TIR) is capable of regulating and supervising the power generation equipment connected to it. By linking and coordinating the operation of gas engines, TIR creates a virtual power plant which may be controlled easily and in a coordinated manner, and thus this virtual power plant can provide system level services and balancing energy, thereby expanding the business opportunities of the equipment. Veolia’s virtual power plant regularly participates at the tenders published by MAVIR for tertiary and secondary controlling capacities, thereby generating significant additional income. Five gas turbines have been connected to the system, thus a 90 MW production unit is available to Veolia. Veolia’s long term objectives include the integration of 120 MW controlling capacity into the system on the level of the portfolio, thus in case of tenders published for 100 MW blocks the company would not depend on the potentials of the smaller competitors.
Health care institutions
Considering energy consumption, hospitals and health care institutions represent a group of consumers with special needs: since the operate on a non-stop basis they have a constantly high demand for heat,in part because hospital rooms need to be heated, and in part because they provide some other services that require heat. With their high demand in heat, the typically outdated and uneconomical systems and the energy supply approach represented by Veolia combined with the technical solutions applied by Veolia these institutions can manage to significantly cut back on energy costs.
State and municipality owned nstitutions and companies
Energy cost rationalisation is a primary issue in day-to-day operation and ensuring competitiveness for production companies, but it can also result in significant savings for the state and municipality owned institutions. Veolia Energia has a decade of experience in providing energy economy related services to actors of the public sector, as well as in the optimization of the energy management of institutions.
As the first step of this, by way of a complex energetics audit the experts of the company assess the operation of the system and the possibilities for savings. Based on the findings of the assessment, Veolia submits a proposal for actions with the help of which energy consumption could be reduced, and it provides a description of development possibilities which could further reduce costs related to the energy economics . Upon request the experts of Veolia will design and perform the necessary developments, they will provide management and maintenance services with respect of the systems, which services include regular monitoring and controlling of the savings results.
