Division BOX — How to calculate the ‘aviation capping mechanism’ in the Renewable Energy Directive

United Kingdom

Original text. Later amendments are not shown.

Assume Country A has a share of aviation energy consumption (AEC) of its total gross final energy consumption (GFEC) of X:

X = AEC/GFEC

Assume X > 6,18 %

In this case the cap implies that for the purpose of assessing compliance,

GFECadjusted = GFEC – AEC + AECadjusted

where AECadjusted = 0,0618 * GFEC

In other terms

GFECadjusted = GFEC – AEC + 0,0618 * GFEC =

= GFEC – X * GFEC + 0,0618 * GFEC =

= GFEC * (1,0618 – X)

The ‘adjustment’ as a % of the real GFEC and as a function of X is therefore

Adjustment = (GFEC – GFECadjusted)/GFEC =

= X – 0,0618

f1

These estimates on energy efficiency and energy savings shall be consistent with other such estimates that Member States notify to the Commission, notably in Action Plans under the Energy Services Directive and the Energy Performance of Buildings Directive. If different units are used in those Action Plans the conversion factors applied should be indicated.

f2

It is the final energy consumption of all energy commodities except electricity for purposes other than transport, plus the consumption of heat for own use at electricity and heat plants and heat losses in networks (items ‘2. Own use by plant’ and ‘11. Transmission and distribution losses’ of Regulation (EC) No 1099/2008 (p. 23-24).

f3

The gross electricity consumption is national gross electricity production, including autoproduction, plus imports, minus exports.

f4

Transport consumption as defined in Article 3(4)(a) of Directive 2009/28/EC. Renewable electricity in road transport for this figure should be multiplied by a factor of 2,5, as indicated by Article 3(4)(c) of Directive 2009/28/EC.

f5

As defined in Article (2)(f) of Directive 2009/28/EC. This comprises final energy consumption plus network losses and own use of heat and electricity at electricity and heating plants (NB: this does not include consumption of electricity for pumped hydro storage or for transformation in electrical boilers or heat pumps at district heating plants).

f6

According to Article 5(6) consumption for aviation has to be considered only up to 6,18 % (Community average), for Cyprus and Malta up to 4,12 % of gross final energy consumption.
