# Commission Decision of 1 March 2013 establishing the guidelines for Member States on calculating renewable energy from heat pumps from different heat pump technologies pursuant to Article 5 of Directive 2009/28/EC of the European Parliament and of the Council (notified under document C(2013) 1082) (Text with EEA relevance) (2013/114/EU), Division 1: INTRODUCTION

Extent: E+W+S+N.I.

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;
(a) the power system efficiency (η or eta);
(b) the estimated amount of useful energy supplied from the heat pumps (Qusable);
(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 2009. 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 2008 on energy statistics. The power system efficiency (η) is set at 0,455 (or 45,5 %), based on the most recent data for 2010, 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.
