ENERGY FOR A GREEDY GLASSHOUSE COMPLEX

Objetivo

Lying between Rotterdam and The Hague, Westland represents one third of Holland's total glasshouse growing area, and is certainly one of the largest European concentrations of this type of activity. There are two key factors in this type of operation : the price of energy/a crucial lack of space. This effort, launched as part of a cooperation scheme between the seven municipalities which make up the region, was aimed at developing an integrated plan permitting the technical, economic and administrative optimization of energy management. This type of plan, which is based on the establishment of a realistic strategy for the future, must serve as a basis for the regional economic players, public authorities, private companies, various bodies and owners to select between different energy options. From the start, priority was given to a strategy based on Westland's own concerns. In the longer term, this strategy could however evolve to include the whole problem of Holland's farming Delta.
TWO-SPEED IMPLEMENTATION
Definition of the integrated energy plan for Westland was completed in early 1985. Estimated potential energy savings from implementation were between 8 and 14% of the region's annual consumption.
The creation, already under discussion, of an integrated water, gas and electricity distribution company combining smaller municipality companies, was confirmed. Establishing this tool, essential for coordinating the different projects to provide rational energy use, was the first task to be accomplished. Despite institutional difficulties, this step was completed in 1988, one year before the original deadline.
Other measures under the plan include :
* fitting individual glass houses with combined heat-force production insulations and with heat pumps;
* large scale developments of these technologies for electrical power stations and industry.
* computerized management of the electricity distribution networks points;
* making use of waste and available water for production and transportation of heat, etc.
These steps have not gone ahead as rapidly. Whilst the application of recommendations directly relating to horticultural enterprises has already produced results, the fall in energy prices since 1985 has slowed down the initiatives necessary for implementing the plan.
The limited financing capacities of the new public company have also reduced the attractiveness of certain projects, for example the organization of a regional network for distributing heat produced from waste.
MULTI-CRITERIA ANALYSIS
The approach used has three steps :
* developing a scenario representing the development of the energy system, including all the factors which are likely to influence regional demand; increase of cultivated areas, energy prices, administrative organization etc,
* selecting a series of energy options according to their feasiblity in terms of cost/benefit analysis, space and environmental impact,
* defining different strategies based on combinations of options and their classification on the basis of a multi-criteria analysis. The reduction in energy expenditure, potential energy savings, employment and the size of the necessary investments are some of the components of the assessment.
