Battery storage for commercial property.

Tenants judge a building by whether the lights stay on. Storage keeps common areas and anchor tenants running, makes rooftop solar worth more and takes the edge off the demand charge.

01 · The problem

What the site
is up against.

Tenants

Outages cost tenants trade

Load-shedding and network faults close shops and empty offices, and tenants notice which buildings stay open.

Solar

Rooftop solar capped at midday

Export limits and low feed-in credits mean surplus solar is curtailed or sold cheaply.

Tariff

Municipal time-of-use and demand

Municipal tariffs charge for peak energy and maximum demand, and recover them from tenants.

What the battery
does about it.

  1. 01
    Backup for the buildingCarries common areas, lifts, security and anchor tenants through an outage.
  2. 02
    Solar self-consumptionStores midday surplus for the late-afternoon and evening load.
  3. 03
    Demand ceilingHolds the monthly maximum demand down.
  4. 04
    Peak shiftingMoves energy out of the municipal peak windows.
03 · Typical configuration

Indicative,
before the load study.

SystemsA100 blocks in 1 MWh steps, or an A200
Connection400 V, three-phase
Duration2 or 4 hours
Pairs withRooftop PV, existing gensets
Commercial modelPPA, so the landlord carries no capex and recovers the energy cost

Every configuration is sized from the site's own interval data and tariff; this is a starting point, not a quote.

04 · Questions

Asked by commercial property
buyers.

Do municipal tariffs work with storage?
Yes. Solaris loads the municipal time-of-use calendar and demand charges for the supply area, which do not always match Eskom's.
How much space does it need?
An A100 is a 10 ft container, 2 991 × 2 438 mm, on a plinth with access and clearance around it.
Can the cost be recovered from tenants?
Under a PPA the building buys energy at a fixed rate, which can be passed through to tenants like any other energy cost.
Next step

Start with your meter data.

Twelve months of interval data, your tariff schedule and your notified maximum demand are enough for a first sizing, an indicative capex and a PPA rate, within five working days, at no cost.
