Your energy, in motion.

Live operations. Measured savings. A clearer view of value.

Measured performance since commissioning
--%
Northmead is spending this much less on electricity-energy than it would have without the solar and battery system. Fixed utility charges are excluded from both sides so the comparison remains like-for-like.

2025 winter proof · customer bill tracker

Northmead proved the concept when electricity was most expensive.

June–August 2025 compared with the same winter months in 2024. This is a deliberately highlighted high-demand-season case study, not the lifetime average.

What this project has proven

Less repetition, more meaning: outcomes that matter to operators and decision-makers.

Lower operating cost
--
Measured energy cost avoided since commissioning.
Less energy bought from utility
--
The system displaces grid purchases with on-site solar and stored energy.
High-value winter protection
83.2%
Reduction in peak-period energy in Jun–Aug 2025 versus the same 2024 months.
Rollout proof
Measured
The operating case is based on real restaurant data, not a theoretical simulation.

Monthly performance scorecard

A compact view of every measured month. Strong months stand out without letting one oversized chart dominate the page.

Savings performance

Measured actual cost versus what the same electricity-energy would have cost without the system.

Selected-period saving
--
Actual measured reduction in electricity-energy cost.
Money kept out of the bill

Measured energy cost avoided in the selected period.

Counterfactual electricity-energy cost using the same measured restaurant load.
Actual energy cost

Energy cost actually incurred with solar and battery operating.

Measured month by month

Every historical month remains visible; the 2025 winter proof is highlighted separately, not substituted for the full record.

2025 winter case study

The battery did its best work when the tariff hurt most.

June–August 2025 is deliberately surfaced as the strongest high-demand season in the customer bill tracker.

July peak energy

August peak energy

Tariff-window change

From 1 July 2025 the winter evening peak became three hours instead of two, running directly through dinner trading.

Before 1 Jul 2025
17:00–19:00
Two-hour winter evening peak.
From 1 Jul 2025
17:00–20:00
Three-hour evening peak. Future storage designs should be sized to the longer window.

If Northmead had not bought the system

Customer-agreed forward model: future electricity-energy tariffs escalate at a fixed 10% per year, regardless of later published increases.

Projected reduction
--
Projection uses measured operating performance as its baseline and escalates Rand tariffs by 10% per year. May and June 2026 and any periods explicitly flagged unavailable are excluded from the forward operating baseline because they were abnormal operating periods. Historical actuals are never removed from the historical record.

Investment value

Capital recovery is important, but it is not the only proof point. Measured operating savings and peak protection remain the primary evidence.

Cumulative value creation

How measured electricity-energy savings have accumulated since commissioning.

Historical record

Every available measured month remains visible. Nothing is removed simply because the operating result was weak.

Trading & Energy Analytics

What Northmead's energy profile looks like on the restaurant's busiest-energy days. Calendar events are context, not proof of sales causation.

Highest-consumption days

If Nando's later supplies daily sales or transaction counts, this can become kWh per transaction, energy cost per R1,000 sales and true sales-energy correlation.

Average restaurant energy by day of week across the available measured history.

From energy analytics to trading intelligence

Energy data can identify high-load trading patterns. Add daily POS sales or transaction counts and the portal can calculate energy per customer, energy per R1,000 sales, grid cost per transaction and whether busy days are becoming more energy-efficient.
