NETA Objectives
• Meet the needs of the customer with respect to price, choice, quality and security of supply
• Enable the demand to be met efficiently and economically
• Enable costs and risks to be reduced and shared efficiently
• Promote competition in energy markets
NETA to date
• Imbalance prices volatility• Extreme system buy/sell prices• High imbalance surplus• PX & Balancing Mechanism prices difficult
to predict• Market prices increasing• Limited demand side participation• Lights still on!
Supplier issues
• NETA penalises Imbalance • Costs higher than anticipated• Imbalance surplus • Lack of GSP Demand limits no. of trading
partners• Unable to unlock CCL value• Renewable obligation• Complex trading arrangements
How you can help?
• Be clear as to what you want• Be clear as to plant capability• Collate & share historic data:
– Site details, MPAN, voltage, hh profile
• Provide generation forecasts (& deviation from)
• Estimate variation from generation forecasts
• Peaking, Standby, Base load or spill CHP, Renewable
• Trading Options:– Independent Trading– Trading through others– Non Party Generation (SVA)
• Contract duration
Trading Options
Trading Options
• SVA - Fixed Prices, Variable Prices
• CVA - Fixed Prices, Variable Prices, Trading
• Participation in balancing mechanism/PX
• Optionality
• Expect – low prices for un-predictability– imbalance pass through
• Ancillary Services
• Supply
Renewable Generators
• Market short - targets high
• Predictable/flexible
• Imbalance still an issue
• Notify non generation in advance
• ROC
• Trade ROC in addition to energy
• Long term contracts available
• Balancing Ancillary Services– “Insurance Policies” to assist NGC in
balancing the Grid in real-time
• Standing or “Fast” Reserve
• Frequency Response
• Others: warming contracts (contingency reserve), voltage constraints, reactive power
Ancillary Services
Energy Management Centre
Primary role to Balance parties energy position
Services on offer:• Registration of BM Units• Submission of Final Physical Notifications (FPN’s)• Submission of bids & offers into the Power
Exchange &
Balancing Mechanism• Facilitate NGC Ancillary Services• Posting of ECVN’s & MVRN’s• Gas - Trading & Optimisation
Summary
• Losers? – Unpredictable/inflexible generators?– Base load generation?
• Winners? – Flexible Users– Risk takers
• Meeting the challenge
