Article 22Design principles for capacity mechanisms
1.
Any capacity mechanism shall:
F37(a)
. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .
(b)
not create undue market distortions F38...;
(c)
not go beyond what is necessary to address the adequacy concerns referred to in Article 20;
(d)
select capacity providers by means of a transparent, non-discriminatory and competitive process;
(e)
provide incentives for capacity providers to be available in times of expected system stress;
(f)
ensure that the remuneration is determined through the competitive process;
(g)
set out the technical conditions for the participation of capacity providers in advance of the selection process;
(h)
be open to participation of all resources that are capable of providing the required technical performance, including energy storage and demand side management;
(i)
apply appropriate penalties to capacity providers that are not available in times of system stress.
2.
The design of strategic reserves shall meet the following requirements:
(a)
where a capacity mechanism has been designed as a strategic reserve, the resources thereof are to be dispatched only if the transmission system operators are likely to exhaust their balancing resources to establish an equilibrium between demand and supply;
(b)
during imbalance settlement periods where resources in the strategic reserve are dispatched, imbalances in the market are to be settled at least at the value of lost load or at a higher value than the intraday technical price limit as referred in Article 10(1), whichever is higher;
(c)
the output of the strategic reserve following dispatch is to be attributed to balance responsible parties through the imbalance settlement mechanism;
(d)
the resources taking part in the strategic reserve are not to receive remuneration from the wholesale electricity markets or from the balancing markets;
(e)
the resources in the strategic reserve are to be held outside the market for at least the duration of the contractual period.
The requirement referred to in point (a) of the first subparagraph shall be without prejudice to the activation of resources before actual dispatch in order to respect the ramping constraints and operating requirements of the resources. The output of the strategic reserve during activation shall not be attributed to balance groups through wholesale markets and shall not change their imbalances.
3.
In addition to the requirements laid down in paragraph 1, capacity mechanisms other than strategic reserves shall:
(a)
be constructed so as to ensure that the price paid for availability automatically tends to zero when the level of capacity supplied is expected to be adequate to meet the level of capacity demanded;
(b)
remunerate the participating resources only for their availability and ensure that the remuneration does not affect decisions of the capacity provider on whether or not to generate;
(c)
ensure that capacity obligations are transferable between eligible capacity providers.
4.
Capacity mechanisms shall incorporate the following requirements regarding CO2 emission limits:
(a)
from 4 July 2019 at the latest, generation capacity that started commercial production on or after that date and that emits more than 550 g of CO2 of fossil fuel origin per kWh of electricity shall not be committed or to receive payments or commitments for future payments under a capacity mechanism;
(b)
from 1 July 2025 at the latest, generation capacity that started commercial production before 4 July 2019 and that emits more than 550 g of CO2 of fossil fuel origin per kWh of electricity and more than 350 kg CO2 of fossil fuel origin on average per year per installed kWe shall not be committed or receive payments or commitments for future payments under a capacity mechanism.
The emission limit of 550 g CO2 of fossil fuel origin per kWh of electricity and the limit of 350 kg CO2 of fossil fuel origin on average per year per installed kWe referred to in points (a) and (b) of the first subparagraph shall be calculated on the basis of the design efficiency of the generation unit meaning the net efficiency at nominal capacity under the relevant standards provided for by the International Organization for Standardization.

F40The Secretary of State must adapt the capacity mechanism that was applied on 4 July 2019 to comply with Chapter 4 without prejudice to commitments or contracts concluded by 31 December 2019.

The F43... resource adequacy assessment F44must cover the territory of Great Britain and shall be based on a transparent methodology which shall ensure that the assessment:
F45(a)
. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .
(b)
is based on appropriate central reference scenarios of projected demand and supply including an economic assessment of the likelihood of retirement, mothballing, new-build of generation assets and measures to reach energy efficiency and electricity interconnection targets and appropriate sensitivities on extreme weather events, hydrological conditions, wholesale prices and carbon price developments;
(c)
contains separate scenarios reflecting the differing likelihoods of the occurrence of resource adequacy concerns which F46a capacity mechanism is designed to address;
(d)
appropriately takes account of the contribution of all resources including existing and future possibilities for generation, energy storage, sectoral integration, demand response, and import and export and their contribution to flexible system operation;
(e)
anticipates the likely impact of the measures referred in Article 20(3);
(f)
includes variants without existing or planned capacity mechanisms and, where applicable, variants with such mechanisms;
(g)
is based on a market model using the flow-based approach, where applicable;
(h)
applies probabilistic calculations;
(i)
applies a single modelling tool;
(j)
includes at least the following indicators referred to in Article 25:
‘expected energy not served’, and
‘loss of load expectation’;
(k)
identifies the sources of possible resource adequacy concerns, in particular whether it is a network constraint, a resource constraint, or both;
(l)
takes into account real network development;
(m)
ensures that the national characteristics of generation, demand flexibility and energy storage, the availability of primary resources and the level of interconnection are properly taken into consideration.

Article 24F48... Resource adequacy assessments
1.
F49... Resource adequacy assessments F50may have a regional scope and shall be based on the methodology F51... in points (b) to (m) of Article 23(5).
F52...
F49... Resource adequacy assessments may take into account additional sensitivities to those referred in point (b) of Article 23(5). In such cases, F49... resource adequacy assessments may:
(a)
make assumptions taking into account the particularities of national electricity demand and supply;
(b)
use tools and consistent recent data that are complementary to those used by the ENTSO for Electricity for the European resource adequacy assessment.

Article 25Reliability standard
1.
F602.
The reliability standard shall be set by the Secretary of State in accordance with regulation 6 of the Electricity Capacity Regulations 2014.
3.
The reliability standard shall be calculated using at least the value of lost load and the cost of new entry over a given timeframe and shall be expressed as ‘expected energy not served’ and ‘loss of load expectation’.
4.
When applying capacity mechanisms, the parameters determining the amount of capacity procured in the capacity mechanism shall be approved by the F61the Secretary of State.
