EPEC helps strengthen the capacity of its public sector members to enter into public–private partnership (PPP) transactions.
To date, EPEC has 41 Members, including the EIB and the European Commission.
All other Members are national or regional authorities that are responsible for PPP policy or programmes in their jurisdictions.
Membership is restricted to public authorities in European Union member states, Candidate Countries and certain other countries in Europe In spite of its overall goal, EPEC also states that "an excessive focus on off government balance sheet recording can be at the expense of sound project preparation and value for money and may push public authorities to use PPPs where not appropriate".
In addition, it admits that PPPs can create an "affordability illusion" which "tends to be exacerbated when a project is found to be off balance sheet.
