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
![Page 8: Renewable & CHP Generators : A suppliers perspective Presentation by Steve Armitage Tel. 0113 289 5369 e-mail: steve.armitage@yeg.co.uk](https://reader036.vdocuments.net/reader036/viewer/2022082709/56649f425503460f94c61ec3/html5/thumbnails/8.jpg)
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

Summary
• Losers? – Unpredictable/inflexible generators?– Base load generation?
• Winners? – Flexible Users– Risk takers
• Meeting the challenge
