NSW Net Zero Plan Stage 1: 2020 – 2030

Key highlights

100% Renewables welcomed the Department of Planning, Industry and Environment’s Net Zero Plan Stage 1: 2020–2030[1], released on 14 March this year, along with the release of two additional Renewable Energy Zones in regional NSW.

While the Plan’s release has been understandably overshadowed by the Covid-19 global pandemic, it is nonetheless a big milestone that sees the first of three clear, 10-year plans released that will set a pathway to net zero emissions by 2050.

It takes an aspirational 30+ year goal and brings it back to tangible actions, cross-sectoral measures, and a range of funded programs that will help governments, business and householders in NSW play their role in moving NSW to a low carbon economy.

From our reading of the Plan, there are a number of key highlights:

  • Action is grounded in science and economics, and a central focus of the Plan is about jobs that will be created and about the lowering of energy costs for consumers. Emissions reductions are a by-product of good investments in new technologies over the long term that boosts overall prosperity. Too much of the negative commentary on decarbonisation is about jobs that will be lost, and more focus is needed on the jobs that will be created, what they will be, and importantly where they will be.
  • We already have many of the technologies to drive significant abatement. Investing in breaking down barriers to these technologies is the simplest and shortest path to accelerating investment in these technologies, like:
    • energy-efficient appliances and buildings,
    • rooftop solar panels,
    • firmed grid-scale renewables,
    • electric vehicles and
    • electric manufacturing technologies.

Electrification and switching to renewables are core short, and medium-term decarbonisation strategies of many of our clients and this focus can help accelerate this transition.

  • The Plan provides certainty to investors that NSW is a place to invest in renewable energy, efficient technologies and sustainable materials. It also signals that NSW aims to lead in the development of emerging technologies that create new opportunities, whilst being flexible to re-assess and re-prioritise efforts during the Plan period.
  • Reducing our emissions by 35% by 2030 and to net-zero by 2050 is a shared responsibility, and the Plan clearly sets out the expectation that all business sectors, individuals and governments must play their part.

  • A broadening of the focus of abatement efforts to encompass low-carbon products and services, integrating these into existing and new initiatives, and providing consumers with more information to influence decisions is welcome.
  • Clarity on some of the funding, targets and programs that will help drive this change, such as:
    • $450 million Emissions Intensity Reduction Program
    • $450 million commitment to New South Wales from the Climate Solutions Fund
    • $1.07 billion in additional funding via both NSW and Commonwealth Governments in a range of measures
    • Development of three Renewable Energy Zones in the Central-West, New England and South-West of NSW to drive up to $23 billion in investment and create new jobs
    • Establish an Energy Security Safeguard (Safeguard) to extend and expand the Energy Savings Scheme
    • Expanded Energy Efficiency Program
    • Expanded Electric and Hybrid Vehicle Plan with the Electric Vehicle Infrastructure and Model Availability Program to fast-track the EV market in NSW
    • Primary Industries Productivity and Abatement Program to support primary producers and landowners to commercialise low emissions technologies
    • Target of net-zero emissions from organic waste by 2030
    • Development of a Green Investment Strategy, with Sydney as a world-leading carbon services hub by 2030
    • Enhancement of the EnergySwitch service by allowing consumers to compare the emissions performance of energy retailers
    • Advocate to expand NABERS to more building types, and improve both the National Construction Code and BASIX
    • Establishment of a Clean Technology Program to develop and commercialise emissions-reducing technologies that have the potential to commercially out-compete existing emissions-intense goods, services and processes
    • Establishment of a Hydrogen Program that will help the scale-up of hydrogen as an energy source and feedstock, and the setting of an aspirational target of up to 10% hydrogen in the gas network by 2030
    • Aligning action by government under GREP with the broader state targets through clear targets for rooftop solar, EVs, electric buses, diesel-electric trains, NABERS for Government buildings, power purchasing and expansion of national parks

We believe that the Net Zero Plan Stage 1: 2020–2030 is a good start in the right direction for NSW. We are looking forward to helping NSW organisations to set and reach their renewable energy and abatement goals, and to avail of available information, support and incentives that help them achieve their goals.

We will be keeping track of the Plan as it is rolled out and evolves over time, and will keep clients informed about opportunities that are aligned with their needs and objectives.

How Randwick Council achieved >40% energy savings at Lionel Bowen Library

100% Renewables has helped many organisations to set ambitious renewable energy and carbon reduction goals and developed the strategies and action plans that will help them get there. While this is one key metric for our business, a greater measure of success is when we see clients implement projects that will take them towards their targets. In this blog post, we showcase measures implemented by Randwick City Council to significantly reduce the energy demand and carbon footprint of the Lionel Bowen Library in Maroubra, Sydney.

Randwick City Council’s climate change targets and plan

Randwick City Council has set a number of ambitious environmental sustainability targets for its operations, including targets for reduced greenhouse gas emissions. In March 2018, Council adopted the following targets:

  • Greenhouse gas emissions from Council’s operations – net zero greenhouse gas emissions by 2030, including but not limited to the following measures:
    • Council’s total energy consumption – 100% replacement by renewable sources (generated on site or off-site for Council’s purposes) by 2030.
    • Council’s vehicle fleet – net zero greenhouse gas emissions by 2030.

Energy eficiency is a key strategy for achieving these goals, as set out in the 100% Renewable Energy Roadmap completed in early 2020.

Lionel Bowen Library energy use and solar

The Lionel Bowen Library is one of Council’s largest energy-using facilties, consuming 7.8% of Council’s total electricity demand in 2017/18. This was after the implementation of a 30 kW solar panel array on the roof of the library in 2013, as well as efficiency measures including VSD control of the cooling tower fan and voltage optimisation of the main incoming supply. The solar array generates 40,000 kWh of renewable energy each year, which is fully consumed within the library.

New energy efficiency projects at Lionel Bowen Library

Concurrent with the development of Council’s 100% Renewable Energy Roadmap, Randwick initiated a project to roll out LED lighting at selected sites, including the library. A multi-faceted process included the

  • development of the business case to secure internal support and approval,
  • selection of a preferred supplier,
  • implementation of a trial ‘LED space’ and measurement of light and energy savings as well as visitor perceptions of the upgraded space,
  • influencing key internal stakeholders to support the whole-facility rollout,
  • implementation including claiming the Energy Saving Certificates (ESCs) for the project, and
  • measurement of the energy savings.

During the development of the 100% Renewable Energy Roadmap it was observed that after-hours control of several of the library’s air conditioning systems was not working effectively. In addition, a storeroom fan system in the basement of the building was observed to be running continuously.

Consultation with facilities management staff indicated that faulty BMS controllers meant that time schedules as well as after-hours controls were not correct, and quotes would be sought for new timers to rectify this. Quotes for a new timer for the storeroom fan system were also sought.

In late 2019, the new time control measures were implemented, with significant immediate energy savings identified in load data for the library. The combined impact of the LED lighting and air conditioning system control changes has been to reduce the library’s electricity consumption by nearly 40% when comparing similar periods of 2017/18 with energy consumption in early 2020. This saving is illustrated below in two charts.

  • The first chart shows monthly electricity consumption from June 2018 through to February 2020, with the steep downward trend in monthly electricity use evident.

Future savings initiatives at Lionel Bowen Library

There are plans to implement additional measures at the library that will see even more energy savings achieved and more renewable energy. These new measures are set out in Council’s 100% Renewable Energy roadmap and include:

  • Installation of a further 30-45 kW of solar PV on the roof of the library which will be absorbed on site.
  • Progressively upgrade the main and split air conditioning systems in the library (which have reached the end of their economic life) with energy efficient systems. This will have the added benefit of removing R22 refrigerant from the library and seeing a switch to a lower-GWP refrigerant. Opportunities to implement VSD control of fans and pumps, and to optimise supply to unused or infrequently used spaces will also be assessed.
  • Implement new BMS controls for new air conditioning plant as this is upgraded.

The combined impact of these changes over time could be a reduction in grid electricity supply to Lionel Bowen Library of 60% compared with 2017/18 electricity consumption.

Progressing towards its emissions reduction target

The energy saving measures implemented at Lionel Bowen Library are just a few among nearly a hundred actions that, when implemented over the next several years will see Randwick City Council realise its goal to reach net zero greenhouse gas emissions by 2030.
