Northern Territory Power and Water Corporation Solar Connection Guide

Key Takeaways

• Connecting solar in the Northern Territory requires an approved connection agreement from Power and Water Corporation (PWC) before installation.
• Jacana Energy is the electricity retailer, and you must contact them to set up your meter for solar after installation.
• Feed-in Tariffs (FiTs) are available for systems under 30 kVA and consumption under 750 MWh per year, subject to a Power Purchase Agreement.
• While the connection agreement is mandatory, specific technical standards for embedded generation from PWC are not publicly detailed in available sources.
• Always ensure your installer is accredited and familiar with Northern Territory connection requirements.

Connecting Solar in the Northern Territory: Your First Steps

If you are planning to install a solar photovoltaic (PV) system in the Northern Territory, the first and most critical step is to secure an approved connection agreement with Power and Water Corporation (PWC). This agreement is a mandatory requirement for all new solar installations before any work commences.

Once your system is installed, you will need to contact Jacana Energy, the electricity retailer for the Northern Territory, to ensure your meter is correctly configured for solar. This step is essential for accurate billing and to enable any eligible feed-in tariffs (FiTs).

Understanding the Roles: PWC and Jacana Energy

In the Northern Territory, two main entities play distinct roles in your solar journey:

1. Power and Water Corporation (PWC): PWC is responsible for the electricity network infrastructure. Their primary role in solar connections is to approve your system's connection to the grid, ensuring it meets safety and network stability requirements. The connection agreement is their formal approval.
2. Jacana Energy: Jacana Energy is the electricity retailer. They handle your electricity billing, offer various tariffs, and administer the feed-in tariffs for solar exports. Electricity retail prices for residential customers in the Northern Territory are regulated and subsidised by the Northern Territory Government.

The Solar Connection Process

Connecting your solar system involves a sequence of steps to ensure compliance and proper operation:

1. Obtain PWC Connection Agreement: Before installing your solar PV system, you must have an approved connection agreement with Power and Water Corporation. Your accredited solar installer will typically assist you with this application process.
2. System Installation: Once the connection agreement is approved, your accredited installer can proceed with the physical installation of your solar PV system.
3. Meter Setup with Jacana Energy: After installation, you need to contact Jacana Energy to request that your electricity meter be set up correctly for solar. This involves configuring the meter to measure both your consumption from the grid and any electricity your solar system exports back to the grid. You can reach Jacana Energy at 1800 522 262 for this service.
4. Feed-in Tariff (FiT) Eligibility: If eligible, you will begin to receive a FiT for the excess electricity your system exports. Eligibility for FiTs applies to residential and business customers who have a solar PV system less than 30 kVA and consume less than 750 MWh per year. Receiving a FiT from Jacana Energy means agreeing to their Power Purchase Agreement.

Northern Territory Electricity Tariffs and Feed-in Tariffs

Jacana Energy offers various electricity tariffs and feed-in tariffs for customers in the Northern Territory. Understanding these can help you maximise the benefits of your solar system.

What you can check yourself, and what you cannot

As a homeowner, you can monitor your solar system's performance via your inverter's display or monitoring app, if available. You can also track your electricity bills from Jacana Energy to see your consumption and any feed-in tariff credits.

However, any work related to the physical connection of your solar system to the grid, modifications to the electrical wiring, or changes to grid-protection settings on your inverter must only be performed by an accredited solar installer or electrician. Grid-protection settings are crucial for network stability and safety, and altering them yourself can breach your connection agreement and pose significant safety risks.

What the published sources do not tell you

While the requirement for a Power and Water Corporation connection agreement is clear, specific technical standards for embedded generation, such as detailed requirements for inverter settings, high solar penetration feeder constraints, or specific export limits, are not publicly detailed in the available Jacana Energy documentation. The process for obtaining the connection agreement is also not fully detailed in these sources.

For precise technical specifications and the full connection agreement approval process, you or your accredited installer should directly consult Power and Water Corporation. Your installer will be able to confirm the specific configuration required for your inverter and system to comply with local network rules, which are set in standards such as Australian inverter connection standards.
