Pipes & Wires

Though leadership of critical energy & infrastructure matters

Issue 221 – August 2023

 

From the editor’s desk…

 

Welcome to Pipes & Wires #221 … this issue starts with a look at the Input Methodology review in New Zealand, and then examines 2 revenue decisions from Australia.

 

We then examine some industry reshufflings in the United States and France, and then examine whether New Zealand’s gas reserves are dwindling as much as the media claims. This issue then concludes by re-visiting the issue of who should own EV chargers. So … until next time, happy reading…

NZ – progress on the Input Methodologies review

 

Introduction

 

The Commerce Commission has recently published its draft decision on the Part 4 Input Methodologies Review 2023. This article examines the key features of that draft decision and notes the next steps. As always, those with a specific interest in this matter should read the Commission’s decisions in their entirety.

 

Regulatory framework

 

The regulatory framework for the Input Methodologies (IM’s) is set out in Subpart 3 of Part 4 of the Commerce Act 1986, with s52V setting out the Commission’s required process and s52Y requiring a review of each IM at intervals of no more than 7 years.

 

The complex themes that the draft decision acknowledges

 

The draft decision notes the complex and uncertain mix of significant themes facing an historically stable electricity distribution sector … expected increases in electricity demand across many customer segments, increased embedded generation and storage, increasing natural hazard risks, supply chain constraints, labor shortages and cost inflation. These themes make predicting revenues, costs and margins much less certain.

 

Key features of the draft decision

 

Key features of the draft decision include…

 

·       The view that the Input Methodologies remain broadly fit for purpose, are flexible enough to cope with the changing environment, but could benefit from specific improvements.

 

·       A clear statement that all businesses operate with some level of uncertainty, and that EDB’s should manage those uncertainties through good planning practices. In particular, EDB’s should move away from deterministic planning to probabilistic and scenario-based planning.

 

·       A view that forecasting uncertainties have increased (which will be dealt with in sector-specific DPP resets).

 

·       The proposed expansion of the availability of DPP re-openers.

 

·       No significant changes to the Customised Price-Quality Path (CPP) Input Methodologies.

 

·       The proposed reduction of the WACC percentile from 67% to 65%.

 

·       The view that the current expenditure incentive mechanisms for equal incentives for CapEx and OpEx.

 

Next steps

 

Following a recent period of consultation, the Commission will publish its final decisions in December 2023 (after which Pipes & Wires will comment further).

 

Network regulatory decisions

 

Aus – the Transgrid final revenue decision

 

Introduction

 

The Australian Energy Regulator (AER) recently released it Final Decision for Transgrid for the 5 year control period commencing on 1st July 2023. This article examines the key features of that Decision.

 

A bit about Transgrid

 

Transgrid owns and operates the high voltage transmission grid in New South Wales and the Australian Capital Territory, comprising 13,000km of 500kV, 330kV, 220kV and 132kV circuits along with 104 grid substations. In 2015 Transgrid was leased to the NSW Electricity Networks consortium for 99 years.

 

Regulatory framework

 

The basis of the regulatory framework is Chapter 6a of the National Electricity Rules, which is made pursuant to the National Electricity Law.

Aus – the Western Power final revenue decision

 

Introduction

 

The Economic Regulation Authority (Western Australia) has released its final decision for Western Power for the 5 year control period starting on 1st July 2023. This article examines the key features of that draft decision to set some context for examining the final decision.

 

A bit about Western Power

 

Western Power owns and operates the transmission grid and distribution networks that supplies the areas stretching from Kalbarri in the north to Albany in the south and then east to Kalgoorlie, through 103,000km of lines and 154 substations. Western Power is owned by the Western Australia State Government, and has an annual revenue of about $700m.

 

Regulatory framework

 

The basis of the regulatory framework is the Electricity Networks Access Code 2004 which is made pursuant to s104(1) of the Electricity Industry Act 2004. Readers will observe similarities to the regulatory framework in the NEM.

Industry reshuffling

 

US – Duke Energy sells commercial renewables to Brookfield

 

Introduction

 

Following recent sales of unregulated renewable assets, this article examines Duke Energy’s recent sale of its commercial renewable assets to Brookfield.

 

A bit about Duke Energy’s commercial renewables

 

Duke’s commercial renewables business includes 3,400 MW of wind and 1,700 MW of solar. Annual revenue is about $1.5b. This business will be sold to Brookfield for $2.8b.

 

Strategies behind the deals

 

Duke’s key strategies include…

 

·       Strengthen its balance sheet and avoid issuing new debt.

 

·       Focus on its regulated businesses (including grid reliability and 30,000 MW of regulated renewables by 2035), with the ultimate goal of becoming a fully regulated company.

 

·       Migrating out of businesses with flattening returns.

 

Brookfield’s strategy includes expanding its 90,000 MW of renewables across the US, and presumably an appetite for assets whose returns are unacceptably low to other owners.

France – fully re-nationalising EDF

 

Introduction

 

Pipes & Wires #216 examined the French governments’ plans to fully re-nationalise Electricité de France (EDF) by buying the 16% of shares it doesn’t already own. This article examines events over the last year.

 

Recapping the proposed purchase and the governments’ thinking

 

The French government proposed to pay about €12 per share (about €9.7b), preferring that people voluntarily sold their shares to the government. The publically stated reasons for the purchase include…

 

·       Giving the Government more ability to restructure EDF (which in hindsight could be interpreted as breakup or sell-off parts of EDF).

 

·       Strengthening the security of France’s electricity supplies as Europe struggles with reduced imports of Russian gas.

 

·       A view that the market is ailing (or possibly failing), as reduced Russian gas supplies increase Europe’s wholesale prices relative to the French Government’s self-imposed price cap. The bigger picture appears to be that a fully nationalised EDF could end up providing electricity below cost as a social services.

 

·       Managing its aging fleet of reactors, along with the cost over-runs of new reactors (of which it plans to build more over the next 20 years).

 

·       A shift in the patterns of Frances electricity import and exports, noting that France would normally be exporting around the northern autumn but is currently importing.

 

Events over the last year

 

The following events have occurred over the last year…

 

·       February 2023 saw the Lower House pass a resolution to fully nationalise EDF, including a rejection to break up or sell off any parts of EDF. That resolution then passed to the Upper House.

 

·       May 2023 saw the appeals court reject a complaint by minority shareholders alleging that €12 per share undervalued EDF. The courts’ rejection of that complaint allowed the re-nationalisation to proceed to completion.

 

·       June 2023 saw EDF return to full state ownership, after 18 years of mixed ownership.

 

This completes Pipes & Wires analysis of the EDF re-nationalisation.

 

US – AEP continues to sell assets

 

Introduction

 

Pipes & Wires #219 examined AEP’s sale of its unregulated wind and solar business. This article examines the possible sale of two further AEP businesses.

 

A bit about AEP

 

American Electric Power owns and operates 31,000 MW of generation supplying 5,600,000 customer in 11 states through 225,000 miles of lines. Key goal areas include having about 50% of its generation to be renewable by 2032 whilst also selling its competitive retail energy business.

 

The proposed sale of AEP Energy

 

AEP Energy is AEP’s competitive retail electricity and gas supplier supplying 752,000 customers throughout Delaware, Maryland, New Jersey, Pennsylvania, Washington DC and Illinois. This sale is proposed for the first half of the 2024 Calendar Year, and will now include AEP Onsite Partners which supplies on-site generation, heat, waste heat recovery and energy storage in 22 states.

 

The proposed sale of transmission joint ventures

 

AEP has yet to decide whether to also sell its 3 transmission joint venture companies Pioneer Transmission, Prairie Wind Transmission and Transource Energy. AEP’s stake in these 3 businesses is valued at about $550m.

 

The strategies behind the sales

 

The strategies behind both proposed sales are to…

 

·       De-risk the business away from kWh throughput which is subject to weather patterns, renewable generation volumes and customer demand.

 

·       Migrate capital back towards AEP’s core transmission and distribution businesses in Arkansas, Indiana, Kentucky, Louisiana, Michigan, Ohio, Oklahoma, Tennessee, Texas, Virginia and West Virginia.

 

Energy mix and grid security

 

NZ – are gas reserves dwindling ?

 

Introduction

 

The Ministry of Business, Innovation & Employment (MBIE) recently released estimates of New Zealand’s gas reserves, and noted a decline since the 2022 update. This article tries to get underneath the media headline that gas reserves are now less than 10 years existing consumption. 

 

Latest gas reserve assessments

 

Key facts from the release include…

 

·       As of 1st January 2023, the Proven + Probable (2P) reserves are 1,635 PJ.

 

·       This is down from 1,967 PJ on 1st January 2022.

 

·       The most significant declines in reserves came from Mangahewa and Maui respectively.

The calendar 2022 year showed a decline in gas consumption due to…

 

·       The closure of the Methanex methanol plant.

 

·       The closure of the Marsden Point oil refinery.

 

·       A warm, wet winter that required less gas-fired electricity generation.

 

Significant factors that are not strongly reflected in the above numbers include…

 

·       Forecast gas consumption is expected to decline further, not increase.

 

·       Contingent (currently not economically viable to extract) gas reserves are estimated to be a further 1,727 PJ, with experience indicating about 67% of contingent reserves end up being viable to extract. That arguably adds another 8 years supply at 2022 consumption rates.

 

·       The above estimates also exclude the recently discovered Toutouwai gas well, which has been described as “significant”.

 

On the assumption that gas consumption does continue to decline, it would therefore seem that there is little truth to the media comment about having less than 10 years’ reserves.

Regulating emerging technologies

 

US – who should own EV chargers ?

 

Introduction

 

Pipes & Wires has previously examined the battle over whether electric companies or third parties should own EV chargers. This article examines a recent move in the US state of Colorado which has seen a major electric company file an alternative transport electrification plan.

 

Recent moves in Colorado

 

Xcel Energy filed its Transport Electrification Plan in May 2023, which proposed to install 460 DC fast chargers owned by Xcel at a cost of about $137. That plan was opposed by a coalition who argued that allowing electric companies to own EV chargers subsidised by electric customers at large would discourage competitive markets for charging.

 

Xcel Energy has subsequently filed a revised plan that includes rebates to assist unregulated third parties to install and own chargers to allow the Colorado PUC and the public to consider both options.

 

Some observations

 

A couple of observations…

 

·       Electric companies have been able to roll out EV chargers quicker than third parties, despite the insistence that third parties are better placed to provide chargers.

 

·       Electric companies are not allowed to include EV chargers in their RAB, meaning that the chargers are not subsidised by electric customers at large.
