Annex VII to the Renewable Energy Directive 2009/28/EC (the Directive) establishes the basic method for calculating renewable energy supplied by heat pumps. Annex VII sets out three parameters that are needed for the calculation of the renewable energy from heat pumps to be counted for the renewable energy targets;

  1. (a)

    the power system efficiency (η or eta);

  2. (b)

    the estimated amount of useful energy supplied from the heat pumps (Qusable);

  3. (c)

    the ‘seasonal performance factor’ (SPF).

The methodology for determining the power system efficiency (η) was agreed in the Renewable Energy Statistics Working Party of 23 October 2009f1. The data required for the calculation of the power system efficiency is covered by Regulation (EC) No 1099/2008 of the European Parliament and of the Council of 22 October 2008f2 on energy statistics. The power system efficiency (η) is set at 0,455 (or 45,5 %), based on the most recent data for 2010f3, which is the value to be used towards 2020.

These guidelines therefore set out how Member States should estimate the two remaining parameters of Qusable and the ‘seasonal performance factor’ (SPF), taking into consideration differences in climatic conditions, especially very cold climates. With these guidelines Member States are enabled to calculate the amount of renewable energy supplied by heat pump technologies.

The value for η in 2010 is 45,5 % (developing from 44,0 % in 2007, 44,7 % 2008 and 45,1 % in 2009), leading to a minimum SPF of 2,5 in 2010. This is a conservative estimate, as the power system efficiency is expected to increase towards 2020. However, as the basis of estimating the power system efficiency (η) changes due to updates in the underlying statistics, it is more predictable to set the η at a fixed level in order to avoid confusion regarding the minimum SPF requirements (create legal certainty) and also to facilitate methodology development by Member States (see Section 3.10). If necessary, η can be revised as per Article 2 (revision of guidelines if necessary by 31 December 2016).
