Insider 23: What’s Happening with Wholesale Electricity Prices in South Australia?

Are recent market outcomes in South Australia the result of too much wind power, high gas prices and constraints, an interconnector outage, exercise of market power, inadequacies in the market rules and industry structure, or perhaps some in combination?

Insider 23: What’s Happening with Wholesale Electricity Prices in South Australia?

The press has been running hot in recent weeks about the state of the wholesale electricity market in South Australia.  In this Insider, we examine market data in detail to understand what is happening.  While many commentators argue that too much wind power in South Australia is driving extreme prices, the data points to a more  complex reality.

The article examines possible factors driving prices including wind power and thermal plant retirement, high gas prices and constraints, an interconnector outage, exercise of market power and possible inadequacies in the market rules and industry structure.  Policy prescriptions will depend on the outcome of such analysis.

Insider 22: Re-engineering the NEM within the Half Hour

In this Insider, we look at a current AEMC rule change proposal to introduce optional 5 minute settlement into the NEM.

Insider 22: Re-engineering the NEM within the Half Hour

The AEMC is currently considering a rule change proposal from Sun Metals to introduce optional 5 minute settlement into the NEM.  The aim of the rule change is to remove the distorted incentives in the current half hourly settlements and to give market participants clearer and sharper opportunities to respond to market needs. 

In this Insider, Hugh Bannister reviews the history of the issue and the current proposal from the point of view of how a control system might be designed and implemented.  He specifically addresses some of the concerns that might inhibit the introduction of such a change including its impact on metering, on contracting and on AEMO and participant systems generally. 

The article concludes that the proposal, with some small but significant adjustments, could be implemented relatively easily and quickly.  It also highlights the fact that Frequency Control Ancillary Services (FCAS) could also evolve to  smooth operations within the half hour and within the 5 minutes as fast response technologies such as batteries become more significant.

WWF Launches its Power Sector Vision for the Greater Mekong Subregion

World Wide Fund for Nature (WWF), with IES and other WWF partners, released its power sector vision to spur the regional and global debate, as well as set out some concrete actions, leading to an achievable, affordable renewable energy future in the Greater Mekong Subregion.

WWF Launches its Power Sector Vision for the Greater Mekong Subregion

WWF worked with Intelligent Energy Systems and partners across the region to develop the most ambitious and detailed analysis of the Greater Mekong Subregion's power sector vision to date. Based on detailed technical power systems modelling of the Greater Mekong subregion, IES developed a regional plan and specific country-level plans for Cambodia, Laos, Myanmar, Thailand and Vietnam.  The power sector vision sets out sensible, cost-effective solutions to some of the region’s most taxing energy problems. The goal of the work was to spur a regional and global debate, as well as lead the way for concrete actions, leading to an achievable, affordable renewable energy future in the Greater Mekong.

Presentation to Vietnamese Delegation on Australian Electricity Market Experience

On 19 May 2016, IES hosted a delegation from the Vietnamese electricity sector. The delegates were senior representatives from the regulatory body (ERAV), Electricity of Vietnam Holding Group (EVN) and the country’s five regional power corporations.

IES presented to the overseas guests on significant NEM milestones and outcomes to date.  There was interest and extensive discussion on contracting and retail competition as well as how NEM traders hedge against spot market price volatility and demand uncertainty. The delegates also appreciated the discussion on NEM contemporary challenges such as network regulation and the integration of new technologies.

The team’s Australian visit was part of the preparation for the Vietnam Wholesale Electricity Market (VWEM), pilot operations of which have been scheduled from 2016 to 2018 and full operation from 2019. IES has been assisting with the VWEM detailed design and rules drafting.

Insider 21: How will energy storage impact the National Electricity Market?

In this edition of IES Insiders we consider what impact energy storage will have on the National Electricity Market (NEM) over the next fifteen years.

Insider 21: How will energy storage impact the National Electricity Market?

In this edition of IES Insiders we consider what impact energy storage will have on the National Electricity Market (NEM) over the next fifteen years. The focus of our analysis is on storage systems installed at residential and commercial premises. Take-up forecasts of energy storage are modelled in a wholesale market simulation tool. The results show the impacts that energy storage will have on wholesale prices, the generation mix, and greenhouse gas emissions.

Myanmar Energy Master Plan Launched in Nay Pyi Taw – 8 January 2016

On 8th January 2016, the Myanmar’s National Energy Management Committee (NEMC) officially launched the Myanmar Energy Master Plan.

Myanmar Energy Master Plan Launched in Nay Pyi Taw – 8 January 2016

IES is pleased to announce that on 8th January 2016, the Myanmar’s National Energy Management Committee (NEMC) officially launched the Myanmar Energy Master Plan at a ceremony at Hilton Hotel in Nay Pyi Taw, following an address by vice president U Nyan Tun.

Work on the Energy Master Plan, the product of work undertaken by IES in association with MMIC, commenced in 2014 under Technical Assistance to the Ministry of Energy under Japan Fund for Poverty Reduction administered by Asian Development Bank.  The integrated plan sets out strategies to ensure a sustainable, affordable and secure supply of energy for Myanmar over the longer-term.  These strategies take account of existing infrastructure, fuel supplies, availability of resources, competency in terms of technology and price, cooperation between the government, public and private sectors, environmental and social factors.

The government, ministries, international non-government organisations, private associations and the ADB collaborated to develop the Master Plan.

Insider 20: Innovating in the Electricity Market

In this Insider article Hugh Bannister, Chairman and CEO of IES and an old hand in the market, lists his Top Seven desirable fixes.

Insider 20: Innovating in the Electricity Market

The National Electricity Market was conceived and designed around twenty years ago.  At the time, it was a small miracle of both technical and institutional innovation.  Like Ford’s model T, it’s been tweaked in many ways since then but under the hood it remains much as it always has been.  It is badly in need of an update to deal with the world as it will soon become.

The challenges are known – the rise of distributed generation and storage, the impact of government policy on renewables and emissions, customer incentives created by skyrocketing retail electricity tariffs and the challenges all this poses for established networks, generation, retailers and customers.  AEMC and AEMO are busy peering into this uncertain future and contemplating responses.

In this Insider article Hugh Bannister, Chairman and CEO of IES and an old hand in the market,  lists his Top Seven desirable fixes.

Insider 19: Will Energy Storage Arrive Sooner with Demand Charges?

In this edition of IES Insider we consider the electricity tariff arrangements that a home equipped with energy storage and solar PV is likely to receive.

Insider 19: Will Energy Storage Arrive Sooner with Demand Charges?

In this edition of IES Insider we consider the electricity tariff arrangements that a home equipped with energy storage and solar PV is likely to receive. We address the question of cost reflective pricing and whether the consumer will be better off with demand charge pricing, or existing pricing structures such as time-of-use.

Why does this matter?

Electricity tariff structures will have a significant impact on the viability and future take up of energy storage technologies. This article presents the results of a recent analysis by IES which tests the proposition that battery storage will become economically viable sooner under a demand tariff.
