Background • Degreed Engineer (Mechanical), MBA • Oil and Gas experience (upstream, capital projects) • Management and energy consulting and consulting • Energy, environmental and capital markets • Various governance roles • NZ Electricity Industry – 7 years (Mco, KEA 3 Ltd, NZX Energy) “We have the gift of a great industry – full of complexity, challenge and change.” “We have not quite sorted industry governance…there is a bit more efficiency to be gained from a collaborative approach to change—one with less input from the general election process” “I try to play nicely with most industry participants….its not too hard if you take the time to listen and understand where people are coming from”
Some thoughts prior to arriving at the SO last month

System Operator – Markets
11
New organisation formed to • Focus on market aspects of operation and development • Internalise competition reliability and efficiency • Smoother travel of idea to implementation
– align better with Authority objectives and work plan – improve industry experience – ensure cost effective delivery
• Enhance commercial and economic awareness in the System Operator
Market Services • Here and now focus • Market support operations • Ancillary services • Heavy project involvement
Development team • 3-15 year view • Specialised technical toolset • Academic leaning • Somewhat independent
System Operator – Markets – current and future work
12
In addition to the joint work plan items, the team is working on: • Study of how Competition, Reliability and Efficiency apply to the SO • Support Strategic planning for market and market systems • Pre-thinking about market/market system architecture circa 2020 • Enhance commercial and economic awareness in the System Operator • Impact of distributed renewables on the market and grid • Observer/support for the Wholesale Advisory Group

Key highlights
• Multiple Frequency Keepers (2014) • HVDC Controls Implementation (2015) • SCADA (PRISM) Upgrade (2015) • Interim Reserve Sharing Arrangements
(2015) • National IR Market (2017 - indicative) • National FK Market (2018 - indicative)
Why do we have one? • The EA is responsible for the New Zealand
wholesale electricity market, and the SO is an important enabler and service provider
• Generally, changes to the wholesale market require changes to market systems and SO processes
• Joint planning allows SO resources to reliably maintain existing services, whilst supporting carefully managed changes (and sequencing efficiency)
When do we do it?
• Must be updated annually - 1st November • Refined through the year with improved
information • Major review completing now • The plan has a nominal 10 year view but
while the view of the first 3 years is clear it gets progressively more fuzzy for the later years
How does it happen?
• The EA/SO meet regularly to review the work plan using best available information
• There are various inputs: – Lifecycle planning – New initiatives (arguably biggest impact to
market) – Improvements to existing services
The effect on market participants
• Most work (e.g. lifecycle) will “just happen in the background” – the effect will be a maintained service level to market participants
• However market initiatives will often require changes to participants’ processes and systems
• These will be signalled well in advance through the consultation process
• How do new initiatives get onto the Joint Work Plan? Aligned with Statement of Intent, and Strategic Directions paper

Security of Supply

• General focus…
MW
… But some of this
What we do
40
• A function that supplies information to participants • Some regulatory function • Produce three main pieces of work that are visible to
the industry:
Security of Supply Annual Assessment
Hydro Risk Curves & Simulated Storage Trajectories (HRCs & SSTs)
Security of Supply Annual Assessment
41
• It assesses the balance between supply and demand over a 10 year horizon
• Derives a series of security margins for each year (winter focus) and for a variety of future generation possibilities
• Compares these margins against standards provided by the EA
• It is a very simplified model • Best to view as metrics or
performance indicators and not exact gauges
Annual Assessment - Results

Annual Assessment – Future work…
43
• We kick off 2015 Annual Assessment in August/September
• Assessment is open to changes and suggestions
• Now is the time to get involved
• Questions or comments on the Annual Assessment…?
Hydro Risk Curves
• Deterministic • Not meant to be
a realistic estimate of market behavior
• Determines when we take regulatory steps to avoid shortage
44
• An objective benchmark showing the risk of shortage the NZ electricity system faces
Simulated Storage Trajectories • Forecast of lake levels using 82 years of inflow data and a market
and transmission system model
45
• Market based valuation of value of water
• Attempts to be a realistic view of what might happen under various inflow sequences
• Subjective as we are predicting how market participants may act
HRCs & SSTs – Future work…
46
• We are always looking to improve our modelling: – Improve risk analysis – Challenge assumptions – Increase usefulness to
industry – Develop awareness and
engagement • Invite suggestions and
challenges to our assumptions
• Questions or comments on the HRCs or SSTs…?
Other areas of development and future work
• Using Security of Supply analysis to assist with wider Transpower decision making – Not just limited to Transpower though…
• Hydrology information review • Policy work
– Preparing System Operator Rolling Outage Plan (SOROP) internal procedure
– Subsequent review of both SOROP and the process around Participant Rolling Outage Plans

Electricity Industry Participation Code
Policy Statement
Security Policy
Background • We review the ‘Credible Event Management’ every 5
years • This current review will consider historic events on the
system, system topology, newly commissioned equipment, modes of operation, and any new regulation
• Link to the EA’s objectives of CRE (Competition, Reliability, Efficiency)
63
Methodology and scope • Credible event identification, including existing events
identified in 2009
• Risk analysis of the identified events via the risk management framework
• Evaluate against our Principal Performance Obligations
• Review the classification of events
• Analyse the costs, determine optimal management
64
Potential outcomes
• Change of the event classification • Procurement of ancillary services • More efficient operation of the grid • The impact of new and upcoming changes such
as HVDC FKC, multiple frequency keeping, AUFLS/extended reserve
65
Next steps
• Identification and analysis of credible events (June/July) • Determine optimal mitigation measures (Aug/Sept) • Conclusions and recommendations (Oct) • Industry feedback on draft review (Nov) • Review finalised and issued to industry (Dec)
