Abstract

The French White Certificate (WC) program, whose goal is to increase energy efficiency in France, launched its fourth period of three years on January 1, 2018, with a new target of energy efficiency savings of 1600 TWhc (TWhc counts the final energy savings over the life span solution actualized at 4%).

During the first three periods, the majority of the WC energy efficiency operations in the French industrial sector focused mainly on energy utilities with the exception of one process, the all-electric injection moulding machine. Our paper aims to analyse the impact of the WC program action since its approval in 2013. This energy efficiency operation replaces a hydraulic injection moulding machine with a completely electrified machine that produces electric savings of up to 50%.

This article will first describe the new and the existing technologies, then analyze the number of WC obtained from this action and the WC market impact. Finally, it will evaluate the size of the operations and the percentage of CAPEX, capital expenditure), covered by the commercial incentives emanating from the WCs obtained via this action. The data used for this study comes from the national WC register, EDF (French Electricity Company), and from a survey conducted by EDF in concert with ADEME (French environmental agency) in 2017.

Between 2013 and 2017 the substitution of hydraulic machines for electric equivalents saved more than 4.7 TWhc of electricity. During this same period sales of the injection moulding machines increased by 50%, more than half of which were all electric or hybrid models. The newer models tend to run between €50k and €400k while on average the WC commercial incentive provides around 5% of the machine total cost (the purchase of the machine itself). The survey results predict a slight growth in the market over the next WC period (2018 to 2020).

Industrial operations such as the injection moulding machine represent more than 20% of WC savings accomplished to date. The wide range of innovations in the industrial sector are an essential and rich field for new WC process operations which must be exploited in order for France to achieve the ambitious energy efficiency targets set for the WC’s fourth period.
