Gridflow provides engineering, advisory, voltage management, microgrid and virtual power plant design and delivery services for distributed energy resource (DER) and large scale renewable energy projects. We allow commercial & industrial property owners to maximise their engagement with the renewable energy to reduce operational costs, improve property utility and achieve carbon neutrality and assist large scale renewable energy developers to overcome curtailment constraints.

Engineering Services

  • Evaluation of renewable energy generation potential across commercial and industrial building portfolios via distributed energy resource (DER) projects.

  • Renewable energy generation audits for capital works projects.

  • Electrical design and engineering for microgrids, embedded networks, photovoltaic systems, wind power systems and virtual power plants.

  • Upstream voltage regulation grid engineering.

  • System testing, commissioning and analytics.

Advisory Services

  • Integration of DER and large scale renewable energy projects into organisational sustainability plans and programs.

  • Specification support and technology licensing for use in distributed energy resource (DER) projects.

  • Funding coordination for large scale renewable projects, onsite power purchase agreements (PPAs) and operating leases for DER projects.

  • DER infrastructure programme management. PPA asset company operator.

  • Project management.

Voltage management as a service (VMaaS)

  • Retrofitting existing behind the meter rooftop solar and wind generators with proprietary voltage regulation technology where these sites have been stopped from exporting energy due to voltage problems they are causing on the network.

  • Removing the zero-export limitation unlocks the energy that was previously not allowed onto the network, creating an income stream that is shared by Gridflow and by the owner of the system.

  • Retrofitting and expanding existing solar and wind capacity and creating an income stream that is shared by Gridflow and by the owner of the system.

  • Installing large new wind and solar systems in sites that would be export limited without proprietary voltage regulation technology managing voltage behind the meter.

Microgrid as a service (MaaS)

  • MaaS can be implemented where large scale solar is installed on the rooftop and/or carpark of C&I properties, and a Battery Energy Storage System (BESS) is integrated into the system entirely behind the meter.

  • The customers for the solar energy produced and the battery services are the occupant of the site and the energy markets.

  • The solar and battery services are provided to the site occupant under an agreement developed by Gridflow called a “Microgrid Services Agreement or MSA” and a licence to use the site owners’ premises for the system installed.

  • Proprietary voltage regulation technology is integrated into the microgrid hardware to perform multiple functions:

    • Acting as an inverter for the BESS. Providing voltage management to ensure 100% export of the solar and BESS to enable energy trading.

    • Providing demand management with BESS.

    • Using proprietary algorithms designed for trading wholesale energy and frequency services markets.

BATTERY AS A SERVICE (BaaS)

  • BaaS can be implemented where a large-scale Battery Energy Storage system is installed at a site that has high available capacity of existing transformer infrastructure connected to the low voltage network (LV grid).

  • A large Battery Energy Storage System is installed to provide demand management services to the building on the site (where required) and trade with wholesale electricity and frequency services markets.

  • Where there is no onsite requirement for battery services then the BESS would be used entirely for market trading or for network demand management and frequency control services.

  • Proprietary voltage regulation technology enables a battery of viable size to be connected to the grid and to provide frequency and demand management services, without the risk of either not being able to install a battery of the desired size or of being curtailed in the future due to voltage problems on the grid.
