Practical examples, realistic assumptions

Case studies focused on efficiency optimization

This page presents representative project patterns and outcomes we commonly model for energy storage systems. Each case emphasizes what the site was trying to achieve, which inputs mattered most, and what was monitored after commissioning. The numbers here are intentionally conservative and expressed as ranges because performance depends on tariff structures, operating hours, equipment behavior, and the control policy used to dispatch the battery.

Primary objective

Peak shaving and tariff shifting

Most business deployments start with measurable cost drivers. We map peaks, propose a dispatch threshold, then validate that the strategy preserves headroom for genuine operational changes instead of chasing every small spike.

Primary objective

Higher renewable self-consumption

For solar-heavy sites, storage often provides the most value when it captures surplus midday generation for evening loads, while keeping a reserve that is not routinely consumed during daily cycling.

Primary objective

Backup readiness for critical loads

Backup-oriented systems succeed when circuits are defined carefully. We treat runtime as a planning range, because actual duration depends on the load selected, temperature, inverter constraints, and the reserve policy.

How to read these case studies

Each case is organized around four elements that tend to determine whether storage delivers ongoing value. First, we define the goal in operational terms, such as limiting grid import above a threshold or raising self-consumption by shifting solar to evening loads. Second, we describe the key data inputs needed to size and control the system. Third, we show the dispatch approach, because strategy matters as much as capacity. Finally, we list monitoring checks that validate performance after installation.

Common data inputs

15 minute or hourly interval consumption
Tariff periods and demand charges
Onsite generation profile (if any)
Operational constraints and critical loads

Commercial

Distribution facility: demand charge reduction with controlled peak caps

Peak shaving

Situation

The site experienced short, high peaks caused by overlapping forklift charging, dock equipment start-ups, and HVAC cycling. These peaks were infrequent but drove a disproportionate share of monthly demand charges. The operational requirement was to reduce the top end of demand without constraining warehouse throughput, and without relying on manual operator intervention.

Approach

We designed a dispatch policy that caps grid import above a defined kW threshold. The system charges during low-tariff periods and maintains a reserve so that unexpected peaks later in the day can still be covered. Instead of targeting every spike, the policy prioritizes sustained peaks that influence billing, and it limits cycling on mild days to protect long-term performance.

Observed operational checks

Peak cap adherence and number of cap events per week
Battery state-of-charge at the start of the highest-risk window
Power quality alarms and inverter temperature trends

Outcome range (typical)

When peaks are driven by a handful of overlapping loads, peak capping can reduce the highest monthly demand readings by a measurable margin. Actual savings depend on the tariff design and how often the cap activates.

Peak reduction: 10% to 25% (scenario-based)
Daily cycling: Partial, targeted to peaks
Key success factor: Stable threshold and reserve policy

Residential

Solar home: evening self-consumption with backup reserve management

Self-consumption

Situation

The household produced surplus solar power around midday but imported electricity during evening cooking, lighting, and HVAC use. The homeowner also wanted practical backup capability for the refrigerator, internet, a few outlets, and selected lighting, while avoiding routine depletion that would leave no reserve when a short outage occurs.

Approach

We set a daily strategy that charges from solar surplus first, then limits discharge so a minimum reserve remains available for backup. On days with lower solar production, the system prioritizes evening coverage rather than attempting to fully offset the entire night. The control window aligns with time-of-use pricing, while still leaving room for unexpected household loads.

Observed operational checks

Share of evening load covered by stored solar energy
Reserve level compliance during normal operation
Number of grid imports during peak tariff window

Outcome range (typical)

Homes with consistent midday surplus often see a meaningful reduction in evening imports. Benefits depend on the solar size, household schedule, and how conservative the backup reserve is set.

Self-consumption lift: 15% to 35% (seasonal range)
Backup readiness: Reserve maintained daily
Key success factor: Right-sized critical circuits

Industrial

Light manufacturing: load smoothing for sensitive equipment start-ups

Load management

Situation

A manufacturing line saw brief inrush events when multiple motors started during shift changes. The issue was not only billing. The site also experienced nuisance trips and occasional process resets that created wasted time and additional wear. The objective was to smooth short ramps and reduce the severity of transients without major changes to production scheduling.

Approach

We proposed a strategy focused on rapid response rather than long duration. The battery dispatch logic targets fast changes in demand, supporting the grid during inrush periods while avoiding unnecessary deep cycling. We also advised a monitoring plan that tracks ramp rates and correlates events to equipment start sequences to confirm that smoothing is happening where intended.

Observed operational checks

Ramp rate metrics during shift change windows
Event logs for trips and process interruptions
Battery response time and power limit adherence

Outcome range (typical)

Fast-response dispatch can improve operational stability by reducing the magnitude of short events. Results depend on equipment sequencing and whether ramps are caused by a small number of predictable starts.

Ramp reduction: Measured per event, site-specific
Cycling profile: Shallow, frequent micro-cycles
Key success factor: High-quality interval monitoring

Want a case study aligned to your load profile?

If you share your site type and the main objective, we can outline a scenario that matches your context. We will ask only for the details needed to respond, and you can request deletion of your information at any time. For the fastest start, include whether you have interval data and whether you operate under time-of-use pricing or demand charges.
