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)

(2013/114/EU)

THE EUROPEAN COMMISSION,

Having regard to the Treaty on the Functioning of the European Union,

Having regard to Directive 2009/28/EC of the European Parliament and of the Council of 23 April 2009 on the promotion of the use of energy from renewable sources and amending and subsequently repealing Directives 2001/77/EC and 2003/30/EC (1), and in particular Article 5(4) in conjunction with AnnexVII thereto,

Whereas:

(1) Directive 2009/28/EC sets out an EU target of 20 % renewable energy in gross final consumption of energy to be achieved by 2020 and contains national targets for renewable energy for each Member State, and an indicative minimum trajectory.

(2) An appropriate energy statistics methodology is necessary to measure the consumption of renewable energy.

(3) Annex VII to Directive 2009/28/EC sets out the rules for accounting of energy from heat pumps and requires the Commission to establish guidelines for Member States to estimate the necessary parameters, taking into consideration differences in climatic conditions, especially very cold climates.

(4) The method to account renewable energy from heat pumps should build on best available science, be as accurate as possible, while not being overly complicated and costly to implement.

(5) Only ambient air, i.e. outdoor air, can be the source of energy for an air-sourced heat pump. However, if the energy source is a mixture of waste energy and ambient energy (e.g. exhaust air from air-circulation units), the method for calculating the renewable energy supplied should reflect this.

(6) Reversible heat pumps in warmer climates are often installed with the purpose of cooling the indoor environment, although they can also be used to provide heating during the winter. Such heat pumps might also be installed in parallel to an existing heating system. In such situations, the installed capacity reflects the cooling demand rather than the supplied heating. As the installed capacity is used as an indicator of heating demand in these guidelines, it implies that the statistics of installed capacity will over-estimate the amount of heating supplied. This needs appropriate adjustment.

(7) These guidelines allow Member States to account for and calculate the renewable energy supplied from heat pump technologies. In particular they set out how Member States shall estimate the two parameters Qusable and the ‘seasonal performance factor’ (SPF), taking into consideration differences in climatic conditions, especially very cold climates.

(8) It is appropriate to allow Member States to undertake their own calculations and surveys in order to improve the accuracy of national statistics beyond what is feasible with the methodology set out in this Decision,

HAS ADOPTED THIS DECISION:

Article 1

The guidelines for estimating the renewable energy production from different heat pump technologies as required by Annex VII to Directive 2009/28/EC are set out in the Annex to this Decision.

Article 2

The guidelines may be revised and complemented by the Commission no later than 31 December 2016, if statistical, technical or scientific progress makes it necessary.

Article 3

This Decision is addressed to the Member States.

ANNEX

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

1. INTRODUCTION

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 (2). 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 (3) on energy statistics. The power system efficiency (η) is set at 0,455 (or 45,5 %), based on the most recent data for 2010 (4), 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.

2. DEFINITIONS

For the purpose of this Decision, the following definitions apply:

‘Qusable’ means the estimated total usable heat delivered by heat pumps, calculated as the product of the rated capacity for heating (Prated) and the annual equivalent heat pump hours (HHP), expressed in GWh;

‘annual equivalent heat pump hours’ (HHP) means the assumed annual number of hours a heat pump has to provide heat at rated capacity to deliver the total usable heat delivered by heat pumps, expressed in h;

‘rated capacity’ (Prated) means the cooling or heating capacity of the vapour compression cycle or sorption cycle of the unit at standard rating conditions;

‘SPF’ shall mean the estimated average seasonal performance factor, which refers to the ‘net seasonal coefficient of performance in active mode’ (SCOPnet) for electrically driven heat pumps or ‘net seasonal primary energy ratio in active mode’ (SPERnet) for thermally driven heat pumps.

3. ESTIMATING SPF AND QUSABLE

3.1. Methodology Principles

The methodology follows three main principles:

(a)the methodology has to be technically sound;

(b)the approach must be pragmatic, balancing accuracy and cost-effectiveness;

(c)the default factors for establishing the contribution of renewable energy from heat pumps are set at a conservative level to lower the risk of overestimating the contribution of renewable energy from heat pumps.

Member States are encouraged to improve the conservative default values by adapting them to national/regional circumstances, including the development of more accurate methodologies. Such improvements should be reported to the Commission and made publicly available.

3.2. Outline of methodology

In accordance with Annex VII to the Directive, the amount of renewable energy supplied by heat pump technologies (ERES) shall be calculated with the following formula:

Where:

Qusable = the estimated total usable heat delivered by heat pumps [GWh],

HHP = equivalent full load hours of operation [h],

Prated = capacity of heat pumps installed, taking into account the lifetime of different types of heat pumps [GW],

SPF = the estimated average seasonal performance factor (SCOPnet or SPERnet).

Default values for HHP and conservative default SPF values are set out in Tables 1 and 2 in Section 3.6.

3.3. Minimum performance of heat pumps to be considered as renewable energy under the Directive

In accordance with Annex VII to the Directive, Member States shall ensure that only heat-pumps with a SPF above 1,15 * 1/η are taken into account.

With power system efficiency (η) set at 45,5 % (see Section 1 and footnote 3) it implies that the minimum SPF of electrically driven heat pumps (SCOPnet) to be considered as renewable energy under the Directive is 2,5.

For heat pumps that are driven by thermal energy (either directly, or through the combustion of fuels), the power system efficiency (η) is equal to 1. For such heat pumps the minimum SPF (SPERnet) is 1,15 for the purposes of being considered as renewable energy under the Directive.

Member States should consider, in particular for air sourced heat pumps, how large a fraction of their already installed capacity of heat pumps have a SPF above the minimum performance. In that assessment the Member States may rely on both test data and measurements, although lack of data may in many cases reduce the assessment to expert judgment by each Member State. Such expert judgments should be conservative, meaning that the estimates rather underestimate than overestimate the contribution of heat pumps (5). In the case of air-sourced water heaters it is normally only in exceptional cases that such heat pumps have an SPF above the minimum threshold.
