Mid-scale solar now earns STCs: what the 1 MW change means for business

From 1 October 2026, commercial solar systems over 100 kW and up to 1 MW can create small-scale technology certificates. What changed, what a system earns, how the 1 MW limit counts the whole site, and the evidence the Clean Energy Regulator wants.

What makes a battery a strategic asset, not just stored energy

Five distinct functions sit on top of the same battery hardware: solar self-consumption, peak demand reduction, time-of-use arbitrage, wholesale market participation and FCAS revenue. A battery performing only the first is a glorified solar accessory. What separates a battery capturing one value stream from one capturing five is the intelligence controlling it, not the hardware.

Why commercial solar alone caps out, and what storage and control add

A well-designed commercial solar installation offsets 30 to 60 per cent of a site's consumption, and then it stops. The ceiling is structural rather than technical: solar generates in daylight while most commercial sites peak in the late afternoon, and feed-in tariffs no longer pay for the midday surplus. Storage, demand response and a control layer are what move a site past it.

  • What integration adds
  • Does solar reduce demand charges?

Demand response · Matt Wigginton · 14 May 2026

How to use demand response at a commercial site

Start with the operating process, not a revenue forecast. A useful demand-response assessment identifies which equipment can change its electricity use, for how long, and under whose authority. This guide sets out the information and trial needed before relying on that flexibility.

  • 1. Find the intervals that matter
  • 2. Record each load’s operating limits
  • 3. Measure the reduction and the recovery
  • 4. Separate bill savings from market participation

Frequently asked

The four questions that come up first.

How is Vitalic different from a solar provider?

Most solar providers focus on generation, installing systems to reduce electricity costs. Vitalic designs integrated energy ecosystems that also manage storage, demand and real-time optimisation. This allows businesses to move beyond cost reduction and actively improve performance, open new revenue streams, and gain greater control over energy.

Is this only suitable for large industrial companies?

No. An integrated energy system may suit a mid-sized commercial business as well as a large industrial site. Suitability and financial outcomes need to be assessed against the site's energy use, tariff and proposed system costs.

How quickly do we see ROI?

Payback depends on the site's energy use, tariff, system costs and operating assumptions. A site-specific assessment is needed before a payback estimate can be stated; no general payback period is promised.

What is demand response and how does it generate revenue?

Demand response allows your business to reduce or shift energy usage during peak demand periods. In return, you receive financial compensation through energy markets. Vitalic enables this through intelligent control systems that automate participation and optimise performance without disrupting operations.
