Measuring the impact of the Fort Island Pampus redevelopment

The background

The Fort Island Pampus Foundation wants to replace its entrance building and restaurant pavilion, with the additional aim of the island operating completely fossil-free. Alliander and its subsidiary Firan are partners with Pampus when it comes to energy supply. Pampus and Alliander want to provide insight into the (potential) impact of the Fort Island Pampus transformation.


Despite having no connection to the mainland, Fort Island Pampus has traditionally been able to provide its own water and energy, thanks to a number of technical innovations. However, the island’s operation now largely depends on diesel generators, with only a small proportion of the total energy demand, approximately 20%, generated by solar panels. The energy supply is balanced by Firan, a subsidiary of Alliander.

The question

Support us in drafting the impact case study for a self-sufficient Fort Island Pampus, providing insight into the financial and ecological impact of the upcoming redevelopment.

Current situation and future

To measure the impact of the transformation of Fort Island Pampus into a sustainable, self-sufficient island, an impact model will be developed, in which different scenarios can be compared. This will create an assessment framework, which can be used to form the basis of decisions relating to the redevelopment and exploitation.

The process

We started by determining the scope, and what we include – and don’t include – in determining the (potential) impact. We did this together with the most important stakeholders. We converted the results into quantitative indicators, collected the data and developed this into an impact model.

The results

The process has resulted in a dynamic impact measurement model that compares the impact of a sustainable, self-sufficient Pampus with that of the existing setup over the period 2020-2040. It is also possible to choose between three scenarios related to the number of visitors to the redeveloped Pampus. This model is a tool the client can use as a basis for future decision making. It shows the conditions under which a self-sufficient island would perform better than the current island from an environmental point of view.

“It’s great that we have invested together with Copper8 in this social impact measurement for the Pampus project, which forces us to face the facts. Content-wise, we tend to concentrate on energy technology and shipping movements. The analysis shows beautifully the contribution we are making through our subsidiary Firan’s sustainable installation. However, to our surprise, the ‘food choice’ at the Pampus restaurant is what will make the real difference. Unfortunately, as a grid operator, we have no influence on this.” Koen Eising CSR Manager
