About the Project
In mixed-use developments the load profiles of different functions diverge sharply: homes peak in the evening, offices and shops during the day, and common-area and external lighting at night. Without careful planning, this diversity leaves some transformers overloaded while others run lightly. Consumption by different operators and user groups also has to be measured separately so that running costs can be allocated fairly.
For a project of this scale, a typical solution is a 2 × 3,200 A main distribution board fed by four 1,600 kVA transformers and divided into two sections. Residential, commercial and common-area loads are grouped on separate outgoing ways, each with its own metering. DevBox boards handle block and floor distribution, DevPower panels take care of landscape and common-area lighting, 2 × 1,250 kVA generators protect life-safety and lift loads, and DevComp keeps the power factor in balance.
Devpan Scope and Switchboard Architecture
Devpan’s scope covers low-voltage distribution from the transformer outgoing ways to block and floor boards and landscape lighting.
- Main distribution boards (DevPanel): 2 × 3,200 A, 65 kA / 1 s, Form 4a – Form 4b, with bus coupler and generator changeover.
- Sub-distribution boards (DevBox): metered supplies for residential blocks, commercial units and community facilities.
- Power factor correction (DevComp): automatic compensation adapted to mixed load profiles.
- Lighting and power panels (DevPower): common-area, car park, landscape and street lighting.

Devpan Products Used in This Project
Project-Specific Engineering Topics
Load diversity planning
Residential and commercial loads peak at different times, so they are balanced across the transformers.
Metering by user group
Residential, commercial and common-area consumption is measured separately so operating costs can be allocated correctly.
Phased energisation
The board architecture allows the development to be energised in phases and extended later.
Landscape lighting control
Street and landscape lighting is managed by astronomical timers and photocells.
Frequently Asked Questions
What is the installed power for the SKP Daho Project?
For a mixed-use development of this scale the installed power is approximately 6,400 kVA, with a typical transformer configuration of 4 × 1,600 kVA. The main busbar is planned at 2 × 3,200 A with 65 kA / 1 s withstand, on a 10 kV MV supply and with 2 × 1,250 kVA standby generators.
How is metering organised in a mixed-use development?
Each user group is supplied from separate outgoing ways with its own meter, so residential, commercial and common-area consumption can be reported independently.
Can the development be energised in phases?
Yes. A sectionalised main board and modular sub-distribution boards allow blocks to be energised at different times and new feeders to be added later.
