One-stop shop for consumer energy data

Get access to high-quality customer datasets for homes, small businesses, schools and more from our energy data store

High-quality residential energy data is a rare and costly commodity, according to energy researchers, which creates a barrier to research and innovation. 
To help fill the consumer energy data gap, and to drive the clean energy transition faster with the power of data, Wattwatchers has created MyEnergy Marketplace.

How it works

1. Households and other electricity consumers get Wattwatchers installed, usually with a discount or other incentive to share anonymised data and receive relevant offers. 

2. Customers accept plain-English user T&Cs in the MyEnergy app (or equivalent third-party service) to authorise their participation.

3. Datasets are managed by Wattwatchers to protect privacy for any personally identifying information, and are hosted on Amazon Cloud servers in Australia.

4. Researchers, solution developers and other data customers define their criteria – such as target locations, grid connection types and load types – and then negotiate terms for access and pricing (which are captured in a Term Sheet).

5. Agreed data access is then delivered through the Wattwatchers API, with access to both real-time and historical/trend data. Other delivery methods such as CSV files also are available.

‘Living’ resource for consumer energy data

MyEnergy Marketplace consists of a continually expanding, ethically sourced and easily shareable dataset from over 5,100 Australian sites under Wattwatchers near real-time monitoring. 

The sites are mainly homes, about three-quarters of them with rooftop solar. But the cohort of sites also includes small businesses, strata complexes, community facilities and schools, and is expanding to add both more sites, and new types of sites such as commercial and industrial (C&I) buildings and property portfolios. The MEM also ingests data from other hardware including utility smart meters and EV chargers

Who is this for?

As well as energy solution researchers and academic institutions, key target customers for our MyEnergy Marketplace fee-for-service business stream include energy market operators, network businesses, energy retailers and a range of non-energy enterprises that use energy data as an input.

Wattwatchers also is working with non-profit community groups and public campaigns, and earlier-stage energy technology startups and solution offerings. They are using MEM datasets and our REST API to develop additional integrations with new features and business models. Data recipients of this nature include solutions for:

  • Optimising EV charging from rooftop solar 
  • Solar and battery scoping 
  • Electric hot water management 
  • Combined FinTech, PropTech, ClimateTech and EnergyTech services (i.e. banking, super, asset management, energy and carbon).
  • Electrification and clean energy campaigns

What does it cost?

Pricing is by negotiation, followed by agreement of a Term Sheet. Data ‘samples’ can be provided on request.

As a guide, the value of data for some of these data services stakeholders has been demonstrated to fall mainly in the range of $150-$250 per device for 3–5 year data sharing agreements. This has been considered excellent value for money by those customers when considering the cost to rollout new devices being $1500 to $2000 per device when factoring in recruitment, training, installation, operations, maintenance, support and project management; and the 1-2 year time delay to wait for installations and 12 months of data to become available.

Wattwatchers, at its discretion, will consider zero-fee data supply for relevant partners including early-stage innovators, not-for-profits, community groups, public campaigns and students.

Focused on the big themes for ‘New Energy’

MyEnergy Marketplace has been built as ‘e-infrastructure’ supporting action on key themes for the clean energy transition, including:

  1. Small-scale and distributed renewables 
  2. Digitalisation, smart grids and data-driven solutions
  3. Consumer empowerment within the electricity system
  4. Net Zero decarbonisation and sustainability
  5. Electrification of everything 


These themes, individually and in combination, are driving increased demand for access to high-quality customer data from researchers, the energy industry, local communities, public campaigns and commercial innovators.

Origins of MyEnergy Marketplace

Origins of MyEnergy Marketplace


Now a standalone energy data as a service business stream for Wattwatchers, MyEnergy Marketplace began its life as the My Energy Marketplace (MEM) commercial-scale pilot, conceived and led by Wattwatchers. In this foundation phase, the MEM was a $9.6 million, Australia-wide project running from October 2019 to June 2023, and was supported by a grant of up to $2.7 million from the Australian Renewable Energy Agency (ARENA).


Guided by a Data Advisory Panel (DAP) – a volunteer panel of external experts drawn from academia, consumer advocacy, the energy sector, data science and sustainability – the MEM focused on striking a working balance between:

  • Consumer energy data access, choice of services and privacy protections, and
  • Secure and ethical data shareability and portability for the benefit of consumers themselves, the electricity system, and the clean energy transition on the other.

Australian National University (ANU) - consumer energy resources project (2023)

The MEM initiative, nominated by Wattwatchers, was named as a finalist in the Climate Technology Impact Award category of the NSW Sustainability Awards, hosted by the Banksia Foundation, in November 2023

ANU researchers from its Battery Storage and Grid Integration Program (BSGIP) were seeking granular customer data to investigate and develop a report on consumer energy resources and load flexibility. Wattwatchers supplied the ANU with access to datasets for a total of 60 sites in the following groups, with 10 sites each for: solar, electric vehicle charging, electric hot water, batteries, air conditioning systems and pool pumps.


The ANU project, called Meter Unbundling, developed a suite of 18 models of new approaches to electricity metering; from concepts that are feasible under Flexible Trading through to thought experiments that explore the reasons why metering exists, and what alternatives might be possible. Its final report urges energy decision-makers to explore metering reform more expansively in the context of energy market flexibility, including further growth in consumer energy resources (CER).


After the project, ANU/BSGIP research engineer Tim Moore told Wattwatchers: High quality residential energy data is extremely rare and valuable, leading to challenges in research data analysis. The Wattwatchers My Energy Marketplace dataset gave us quick access to dozens of end-points monitoring hundreds of individual devices, allowing us to perform a far deeper analysis than we expected would be possible – greatly improving our research outcomes and the impact we were able to create. The data was easy to access and required very little pre-processing, saving time and allowing us to get straight into the research with almost no overhead. We’re already planning our next data project using this great resource!
