What is an off-grid solar system?

TGR Energy can integrate embedded networks or microgrids into a network to increase the solar power benefits.

Do you have an embedded network at your site? If so, would you like to add solar energy to it? Are you interested in setting up an embedded network for your solar PV system?

TGR Energy can help you!

We have a lot of experience in integrating PV into existing embedded networks and microgrids.

What is an embedded network?

Embedded networks (also known as microgrids) are privately-owned and managed electricity infrastructure. They are usually located in apartments, shopping centers, airports, or multi-tenanted precincts. Grid-connected, embedded electricity networks are also available. They are connected to the grid by consuming electricity from the main meter box. Electricity is bought at bulk discounts and then sold to tenants at reduced rates. The embedded networks can be managed independently of the main gate meter.

What is an embedded network?

Yes, several!

  • Embedded networks increase electricity retailing competition and put downward pressure on energy prices.
  • By diversifying your site’s electricity mix through the addition of solar PV and solar batteries, you are future-proofing your operation, and gaining some buffer from rising electricity costs.
  • Embedded networks allow much more detailed energy management and efficiency, resulting in lower energy consumption across the board. This is not just great news in terms of showing your organisation cares about corporate responsibility and projecting an environmentally sound image into the market place, but also for Australia as a nation with the highest carbon emissions per capita in the world.
  • Billing usually happens monthly rather than quarterly, allowing consumers more control over their budgets.

CAN SOLAR BATTERIES BE ADDED TO EMBEDDED NETWORKS

Definitely. You can save even more money by adding battery storage to your embedded solar-powered network. This will allow you to cover your site's electricity consumption at night as well as during the shoulder hours of the morning and afternoon.

What are the essential elements of embedded networks designed by TGR Energy?

  • One gateway meter that is the only point of connection to the network and therefore only one bill from the retailer for the whole site (bulk buying power provides cheaper rate).
  • Owner/tenant meters which measure the electricity consumption for each separate office or apartment.
  • Solar power system to provide energy to the embedded network even cheaper than it can be purchased.
  • Commercial scale battery such as Tesla Powerpack to maximise the self-sufficiency of the entire embedded network.

Can embedded networks with solar PV produce electricity?

Yes, but it is dependent on the local grid regulations and requirements. A solar-powered embedded network that generates passive income from selling excess electricity to the grid can be approved for export.

TGR Energy can create an embedded network with a zero export solar system to meet local electricity needs if the export is denied. Your request to export solar electricity might be approved as the grid and national electricity markets evolve. We can upgrade your zero export solar system to allow for export.

What are the savings I can make with an embedded solar-powered network?

It will all depend on your roof size, solar potential, energy intensity, and budget.

Brisbane Technology Park expects to reduce grid power costs by having them. This is possible through the addition and export of unused electricity to the main grid. Investors will be happy with the higher investment returns. Tenants also win as their electricity prices will remain the same at 2017 prices for many years.

CAN SOLAR BATTERIES BE ADDED TO EMBEDDED NETWORKS

Definitely. You can save even more money by adding battery storage to your embedded solar-powered network. This will allow you to cover your site's electricity consumption at night as well as during the shoulder hours of the morning and afternoon.

What are the essential elements of embedded networks created by TGR Energy?

  • A gateway meter is the only point of connectivity to the network. This means that there is only one bill from the retailer per site. Bulk buying power offers a cheaper rate.
  • The owner/tenant meters measure the electricity consumed by each apartment or office.
  • The embedded network can get energy from the sun using a solar power system that is cheaper than buying it.
  • Tesla Powerpack is a commercial-scale battery that maximizes the self-sufficiency and reliability of the embedded network.

Why is it that large energy consumers (over 100 000 kWh annually) pay less electricity?

Large electricity users often buy bulk to get better supply rates and lower network charges. The area where bulk buyers live may have electricity prices that are half the price. This results in embedded networks being more profitable.

Can an embedded network be used off-grid?

Although it is possible, the process can be quite complex! It is still rare to find embedded networks or microgrids not connected to the grid. "Microgrids in I landed Mode" is often used to describe towns, suburbs, and precincts that go completely off-grid. This is different from a grid-connected microgrid or hybrid microgrid, which can switch between them. Many microgrid trials and examples are being conducted around the globe, including in rural Australia. Although technology is moving towards decentralized electricity grids, it is still difficult and expensive to set up an entire town or suburb as an embedded microgrid or embedded system.

> Having the grid as a backup is a good idea for now. But, keep an eye on this space!
