More detail on RfG – Generator Banding
- Technical requirements in RfG are arranged into x4 Types based
- n a user’s connection voltage and MW capacity
- Type A - B requirements are close to a product standard
- Type C - D requirements need active user management
- GB levels will apply consistently across Scotland and England +
- Wales. The local TSO (NGET) will make a proposal for the levels -
this is then ratified via industry consultation and regulatory approval
Maximum RfG banding levels permitted for GB: Type Connection Voltage Capacity A < 110kV 800 W – 1 MW B < 110kV 1 MW – 50 MW C < 110kV 50 MW – 75 MW D > 110kV 75 MW +
Current GB Levels: Generator Size SHET SPT NGET Small <10MW <30MW <50MW Medium 50-100MW Large >10MW >30MW >100MW

Update: Review of transmission charging
- In light of significant change in recent years, e.g. decentralisation,
decarbonisation and new technologies; we believe Transmission charging and commercial arrangements need holistic review
- This was supported by feedback from two dedicated charging
seminars held in July (outputs here: Charging Review Website)
- Feedback from these seminars has informed the scope and
approach of a review. At TCMF on 08/12/16 we presented further thoughts on the next steps. These are grouped in three areas… 1. Quick wins – a number of activities are progressing, including CUSC mods on half hourly charging (CMP266), a policy paper on storage (early 2017) and improvements to tariff forecasting. 2. Holistic review – we want to work with Ofgem to ensure their areas of work around embedded generation are comprehensive, particularly with regards to flexibility. 3. Stakeholder forum – we want to establish a forum to discuss broader industry reform and develop a route-map for change
26
SLIDE 27
Other Grid Code mods
GC0096 – Storage is a new workgroup kicking off in early 2017 In conjunction with the BEIS/Ofgem call for evidence on Flexibility, it will define (Electricity) Storage in the Grid Code, and make clear what technical requirements are required for: Stand-alone Storage connections, and... Storage configured with existing generation or demand units For more details on how to get involved please email Grid.Code@nationalgrid.com

Market Design
Capacity Allocation & Congestion Management (CACM) Guideline
- Implicit Day Ahead & Intraday cross border trading
- Bidding zone reporting process and subsequent review
Forward Capacity Allocation (FCA) Guideline
- Long term transmission rights;
- Physical Transmission Rights (PTRs) with Use It or
Sell It (UIOSI)
- Financial Transmission Rights (FTR) options
- FTR obligations
- Single Allocation Platform with Harmonised Allocation
Rules
Regional Capacity Calculation
- CACM and FCA both increase regional TSO
coordination with capacity calculation used to determine interconnector capacities
- Calculation underpinned by a pan- EU Common Grid
Model (CGM)
It establishes a platform for managing capacity & flow around the interconnected system to facilitate a single EU market

CACM and FCA have been published and become law within the UK;
- CACM entry into force 14 Aug 2015
- FCA entry into force 17 Oct 2016CACM
and FCA now requires T TSOs, NEMOs to draft, consult, and submit proposals to regulators on detailed design aspects. CACM proposals largely complete by end
- f 2018, FCA by end of 2019.
Any changes to GB codes to implement CACM and FCA will be raised and consulted

NG and other TSOs will develop new processes to increase regional coordination Trading Interconnector capacity in the forwards markets trading cross border energy in the day-ahead & intraday timeframes Generators and demand to provide information on which TSO decisions are made on a regional basis (see Common Grid Model) Power exchanges (in their new role as NEMOs) will develop new processes to deliver a pan-EU marketplace Interconnector owners (current and future) will operate under new rules, including new requirements on interconnector firmness

CGM built at D-2 CGM built at D-1
Common Grid Model (CGM)
- A European-wide network model assembled from each TSO’s
individual grid model (IGM)
- Realistic and accurate representation of the Transmission &
Distribution networks
- One scenario for each market time unit (1 hour)
- Built to a common standard with a harmonised modelling approach
- Used as a key tool for many new coordinated European processes –
- incl. capacity calculation
Each TSO’s IGM is built using the latest available data from market participants for specific delivery times
