No Solar in the Plan? Assess a Business Battery on Its Own Merits

Start with the battery decision, not an assumed solar project

If solar is not part of your NSW business’s current plans, how should you approach a commercial battery proposal? Start by asking whether the proposed battery has a clear purpose and an investment case without relying on a future solar installation.

The NSW Government’s battery storage guide says business batteries can help manage energy use and may reduce peak demand charges, but suitability needs investment assessment. That is a reason to investigate, not a reason to assume a purchase is justified. Keep the question narrow: what would this proposed battery do for this business under the conditions being assessed?

Keep future solar outside the base case

Ask for an assessment that separates your present proposal from any optional future solar scenario. If solar has not been agreed, its assumed contribution should not be necessary to make the battery recommendation look worthwhile. You can consider a combined option separately without treating it as a commitment.

If you later investigate solar, the Australian Government identifies electricity use and timing, budget, sunny roof space and installation complexity as sizing considerations. Those questions deserve their own assessment. For now, ask: would we still consider this battery if solar never proceeded? If the answer is no, pause the standalone proposal rather than approving it on an unconfirmed plan.

Ask what energy management would mean here

‘Managing energy use’ needs to become a specific objective before it can support an investment decision. Ask the assessor to explain what change the proposed battery is intended to make, which information supports that expectation, and which assumptions still need checking.

For a warehouse, hospitality venue, manufacturer, retailer or medical business, the useful question is not whether batteries benefit that business category generally. It is whether the proposed arrangement addresses this site’s stated need. If peak demand charges are part of the case, ask whether they apply under your electricity arrangements and how the claimed benefit would be assessed. Tariffs vary by customer and location; a general example is not your business’s result.

Treat outage support as a separate requirement

If the attraction is keeping the business supplied during an outage, say so explicitly. Australian Government guidance states that a battery supplies outages only when configured for backup. Do not interpret a battery proposal, or an energy-management benefit, as confirmation that backup is included.

Ask whether the proposed configuration would support your intended outage requirements and what remains to be resolved. If backup is essential but the proposal does not establish it, that is a reason not to proceed with that proposal. Conversely, if backup is not required, do not count it as an investment benefit merely because the equipment is described as a battery.

Use a standalone-battery decision checklist

Before committing, work through these questions and record the answers. What is the battery’s primary purpose? Has the assessment excluded uncommitted solar benefits? Which electricity-use and tariff assumptions underpin the recommendation? Are any proposed peak demand benefits relevant to your arrangements? If outage supply matters, is backup configuration explicitly addressed? Does the investment assessment support proceeding without a later solar project?

Leave unresolved answers visible rather than filling them with optimistic assumptions. Reasons not to buy include an unclear purpose, an investment case that only works with unapproved solar, or an essential backup requirement that has not been established. Deferring the purchase is a valid outcome when the assessment does not support it.

Make the next step specific to your NSW site

Bring your current electricity arrangements, stated battery objective and any separate solar intentions to the discussion. Ask for the battery-only case to be distinguished from optional alternatives, with uncertainties clearly identified.
