Pipes & Wires
From the editor’s desk…
Welcome
to Pipes & Wires #177. This issue starts with 3 network access decisions in
NZ and the UK, and is followed by an examination of smart meter cost recovery
being rejected. We then look at two grid security issues in the US (but which
could happen anywhere), and conclude with an examination of a huge merger in
Australia and a summary of recent merger activity in the US. So … until next
month, happy reading…
What we’re seeing…
· Some regulators warming to the idea of
allowing a “sand pit” for electric companies to play with emerging technology
ideas in, and allowing recovery of the reasonable costs of that playing.
· Increasingly mixed messages about
closing down coal-fired station to reduce emissions on the one hand, and
keeping them open to improve grid security on the other hand.
· Regulators defining multiple classes of
services and payment categories for battery storage.
· Diversified electric companies reducing
their exposure to volatile energy revenues and increasing their exposure to
predictable lines revenue (the opposite of what was fashionable a few years
ago).
· Legacy thermal generation facing
steeper evening ramping rates as solar hollows out the daily demand profile.
· Heightened appreciation of coal-firing capability
during gas supply interruptions.
· A shortage of skilled project managers
and electricity network designers.
· Gas
turbine stations being recognised as important for providing grid security.
· A mixed bag of revenue determinations …
some tougher than expected, some easier.

Network access policy & decisions
NZ –
setting the 2020 – 2025 default price path
Introduction
Non-exempt
electricity distribution businesses (EDB’s)
are currently regulated by a default price path (DPP) running from 1st
April 2015 to 31st March 2020. This article examines the Commerce
Commission’s proposed process for
setting the next DPP which will start on 1st April 2020.
Regulatory
framework
The regulatory framework for the DPP is set
out in Subpart
6 of Part 4 of the Commerce Act 1986. This
framework requires the Commission to reset the DPP 4 months prior to the end of
the existing DPP ie. by 30th November 2019.
Key
features
The Commission has signaled that it will
focus on the following features as part of its consultation process…
· Starting
prices and rates of change.
· Quality
standards.
· Performance
and efficiency incentives.
· Rules
around demonstrating and assessing compliance.
· Implementing
the changes from the 2016 Input Methodologies review.
· The
CapEx and OpEx forecasts that the financial model is based on.
As always, interested parties should obtain
and read the entire document.
Next
steps
The Commission expects to
publish the DPP Issues paper in November 2018, its Draft Decision around May
2019, and its Final Decision in late November 2019.
UK – the RIIO - 2 regulatory framework
Introduction
The UK’s electricity networks and gas
pipelines are currently regulated under the RIIO – 1 framework, which focuses
more on incentives and innovation rather than prescriptive cost categories (the
former RPI – X framework). This article examines the likely features of the
impending RIIO – 2 framework.
The current RIIO – 1 framework
The electricity and gas regulator Ofgem
introduced the RIIO – 1 framework in 2013. In contrast to the former 5 year RPI
– X framework, RIIO – 1 adopted an 8 year control period. The current RIIO – 1
controls include…
· RIIO – T1
covering the high-pressure gas transmission business and the 3 high-voltage
electricity transmission businesses for the period 1st April 2013 to
31st March 2021.
· RIIO – ED1
covering the 12 electricity distribution businesses for the period 1st
April 2015 to 31st March 2023.
· RIIO – GD1 covering the 8 gas distribution businesses
for the period 1st April 2013 to 31st March 2021.
Likely features of the RIIO – 2 framework
The likely features of the RIIO -2
framework include…
· A move from 8 year control periods back to 5 years.
Ofgem acknowledges that an 8 year control period could provide more planning
certainty for electric and gas companies, but also argues that a 5 year period
provides an opportunity to reset customer prices as the industry rapidly
changes.
· An expectation that electric and gas companies will
work with closely with the respective system operators to invest for the lowest
overall supply chain cost.
· An expectation that the nation-wide electric and gas
bill will reduce by about £1b per year for each of the 5 years, of which part
will come from reduced investor returns.
· Requiring electric and gas companies to justify their
investment plans more robustly.
· An expectation of increased active demand management
focused on customers recognising when they can use electricity more cheaply.
Next steps
Ofgem has recently
consulted on its draft RIIO – 2 framework, and will publish its final framework
in mid-2018.
UK – the PR18 rail access draft decision
Introduction
Pipes & Wires #173 examined
the key features of Network Rail’s CP6
Strategic Business Plans for
the CP6 control period from 1st April 2019 to 31st March
2024. This article examines the Office of Rail and Road’s draft
decision.
Key features of the draft
decision
Key features of the draft
decision include…
· A requirement for further engagement with the train operating
companies on performance trajectories.
· An expectation that costs will be reduced by about £1b.
· Whilst stakeholder engagement was good, it could be improved. In
particular some stakeholders felt that the engagement process was more like communicating
a pre-determined outcome.
· An expectation of more explicit trade-offs around competing
priorities.
· Concerns about the tracks’ ability to accept specific types of
freight rolling stock, including speed, availability and electrification.
Next steps
The ORR expects to publish its
final decision in October 2018.
Regulating emerging technologies
US – rejecting advanced meters
Introduction
Rejecting the recovery of costs from previously ordered initiatives is
nothing new. This article examines the Massachusetts Department of Public
Utilities recent rejection of advanced metering proposals.
Massachusetts’ grid modernisation plan
The Massachusetts’ Department of Public Utilities issued
Order 12-76-B in June 2014, which
required all electric companies in the state to file Grid Modernisation Plans
outlining how they intended to achieve the following outcomes over the next 10
years…
· Reducing the effects of outages.
· Optimising demand.
· Integrating distributed resources.
· Improving workforce and asset management
The principal feature of the Order was that electric companies were to
prioritise advanced metering functionality (which the Order states forms the
basic technology platform for grid modernisation), and such advanced metering
functionality would receive preferential regulatory treatment.
The DPU’s decision
The DPU recently rejected the advanced metering
components of several grid modernisation plans, claiming that the evidence
provided revealed weaknesses in the business cases presented, and now plans to
work with electric companies on more targeted roll-outs of advanced meters that
will yield benefits in line with the costs. The DPU went on to state that
grid-facing technologies (eg. Advanced DMS, voltage optimisation etc) lay the
foundational framework for grid modernisation (which seems to differ from the
previous claim that advanced metering was the foundation).
Previous disconnects
Pipes & Wires #93 and #94 noted a similar
disconnect in the US state of Maryland, in which noted Baltimore Gas
& Electric’s plan to install smart meters under the encouragement of the
state government was rejected by the Maryland Public Service Commission (PSC) on the basis that the benefits
to customers were “largely indirect, highly contingent and a long way off”.
Energy
mix & grid security
US –
keeping the lights on in the Lone Star State
Introduction
Keeping the lights on as
summer air conditioning loads reach ever-increasing peaks seems to be a topical
issue (indeed it was the keynote theme at the recent Energy Networks 2018
conference in Australia). This article examines how the Electric Reliability Council of Texas is coping with this summers’ peaks.
Recent demand peaks in Texas
Demand in the ERCOT
region recently reached 61,500 MW (which is 2,200 MW higher than the previous
peak demand in May 2017), whilst prices peaked to $1,500 per MWh.
Texas’ supply and demand situation
ERCOT’s forecasts are as
follows (derived from ERCOT forecasts which show demand exceeding installed
capacity)...

This table shows that
simply meeting forecast demand in the 2023 summer depends on over 4,400 MW of
new (secure) generation being commissioned within 5 years.
Likely responses to meet demand
Likely responses to meeting
demand include….
· Commissioning of gas-fired generation earlier than expected.
· Returning moth-balled generation to service.
· Re-scheduling generation shutdowns.
· Possibly intervention by ERCOT to deploy contracted emergency
generation.
· Voluntary load reductions.
· Injection from industrial customers with their own generation.
US – replacing gas turbines with batteries
Introduction
Pacific Gas & Electric
recently requested approval from the California Public Utilities Commission (CPUC)
to install 4 energy storage projects. This article considers the issue of
large-scale battery storage on several dimensions.
The context
The California Independent
System Operator (ISO) identified the following gas-fired generation plant as critical
to the security of PG&E’s South Bay and Moss Landing transmission regions…
· Metcalf – a 605 MW combined-cycle plant in the Coyote Valley are of South
San Jose.
· Feather
River – a 47
MW simple-cycle gas turbine plant in Yuba City.
· Yuba City – a 47 MW simple-cycle gas turbine plant also in Yuba City.
These plants are owned by
Calpine and operated by agreement with PG&E. Various views on assigned
reliability-must-run (RMR) status to those generators was as follows…
· Calpine supported using RMR contracts.
· The California ISO also supported using RMR contracts, but opposed
some of the terms.
· The FERC recommended that the CPUC approve the agreement.
· The CPUC opposed using RMR contracts.
· PG&E opposed using RMR contracts.
Key reasons for opposing the
use of RMR contracts was possible market distortions, higher costs (many
analysts claim that batteries are now cheaper than gas turbines), and CO2
emissions, but in the end it was determined that the 3 plants were essential to
grid security.
Tendering for support
In keeping with the trend of
seeking third-party provision of constraint relief, the CPUC
authorized PG&E to
hold competitive solicitations for energy storage and / or preferred resources
to meet specific local area needs in 3 specified sub-areas. New Zealand readers
might want to think about seeking third-party relief of constraints (eg.
batteries, diesel generators, interruptible tariffs etc) in the context of the
Related Party Transactions (pg 73 of the Related Party
Transactions Input Methodologies Review Final Decision and Determinations
Guidance 21 December 2017).
The proposed batteries

Key issues to think about
A couple of key issues to think
about include…
· The levelised cost of batteries is now considered to be less than
the cost of gas turbine generation, and that presumably depends on the price of
delivered gas.
· Regulatory treatment of batteries still seems a bit immature, with
many energy companies claiming that lines companies should not be able to
simply add the cost of batteries to their RAB.
· Will batteries really provide a similar level of grid security as
gas turbine generation ? The evidence from the Australian NEM is that the
Hornsdale battery in South Australia has performed very well during recent grid
excursions that lasted for seconds, but how well might batteries perform if
those excursions extend from seconds to hours or even days ? Another angle of
thought might be that batteries should be considered as a complement for gas
turbines rather than a substitute.
Mergers
& acquisitions
Aus – CK Infrastructure bids for APA Group
Introduction
Last month CK Infrastructure launched an unsolicited bid for the APA Group, Australia’s largest gas pipeline operator. This article examines
the initial bid to set some context for further analysis.
A bit about CK Infrastructure
CK Infrastructure owns and
operates a wide range of electricity, gas, water, rail, airport and roading
assets in Australia, New Zealand, Europe, Canada and Asia. Australian assets
include…
· SA Power Networks in South Australia.
· CitiPower and Powercor in Victoria.
· DUET, which owns MultiNet Gas and 66% of United Energy in Victoria.
· Australian Gas Infrastructure Group in NSW, Victoria, the Northern Territory, South Australia,
Queensland and Western Australia.
A bit about APA Group
APA Group owns 15,000 km of gas transmission pipelines, along with gas
distribution networks in south-east Queensland (Allgas) and Tamworth, NSW.
Details of the bid
CK Infrastructure’s bid of
A$13b represents a 33% premium to APA’s closing stock price. Such a premium
suggests that CKI has identified tranches of value that are not recognised by
APA’s stock price, most likely…
· Amalgamation synergies.
· Expectations of favorable regulatory decisions.
· Expectations of increased gas transmission volumes.
What might an enlarged CK Infrastructure look like ?
Huge is probably the best word.
And vertically integrated. An enlarged CK Infrastructure will have electricity
distribution, gas distribution or gas transmission assets in all jurisdictions
except Tasmania.
Pipes & Wires will comment
further as the bid progresses.
