Commercial electricity challenges

Energy is now a strategic operating risk.

For commercial operators, power affects operating cost, uptime, tenant and guest experience, and reporting obligations.

01

Diesel dependency

Standby generators carrying daytime office, hotel or hospital load for hours, with volatile fuel prices and supply logistics.

02

Tariff exposure

Band A and maximum-demand tariffs combined with unpredictable feeder availability.

03

Critical-service continuity

Changeover gaps disrupt servers, medical equipment, lifts and guest services.

04

Power quality

Voltage dips and imbalance affect HVAC compressors, IT equipment and sensitive devices.

05

ESG reporting

Tenants, investors and group headquarters increasingly require measurable emissions reduction.

06

Asset reliability

Ageing generators with rising maintenance cost and failure risk.

Load profiling

We measure before we design.

Commercial systems are sized from interval data, not estimates. We log your building’s consumption to understand base load, peaks, occupancy patterns and generator behaviour.

  • Power-quality and load logging on main incomers (typically 7–14 days)
  • Review of utility bills, diesel purchase records and generator hour meters
  • Identification of critical, deferrable and shiftable loads
  • Base-load, peak-demand and night-time energy analysis

Hybrid, off-grid and storage

Choosing the right architecture.

Hybrid (grid + generator + solar + storage)

The most common commercial configuration. Solar serves daytime load, storage covers outages and evening peaks, and generators run only when required — at their most efficient loading.

Off-grid / captive power

For sites without reliable grid supply. Solar and storage form the primary source with generators as firm backup, designed around autonomy and reserve margins.

Battery energy storage

Storage provides seamless backup for servers and medical equipment, reduces generator start-ups and absorbs surplus solar. Chemistry, C-rate and cycle life are chosen against your duty cycle.

Assumptions and method
  • Annual generator cost = (litres/hour × fuel price + maintenance/hour) × hours/day × days/month × 12.
  • Solar operating cost = remaining generator & grid spend × (1 − solar contribution) + O&M.
  • Annual savings = current annual spend − solar operating cost. Payback = system cost ÷ annual savings.
  • Five-year view applies the annual cost increase to fuel and grid spend, includes the system cost upfront, and includes battery replacement only if it falls within five years.
  • Excludes financing costs, generator resale value and changes in your usage.

FAQs

Commercial questions.

Do I need a three-phase system?

Three-phase systems are typically required where the building has a three-phase supply and significant three-phase loads such as large motors, lifts or industrial equipment. Many homes and small businesses operate on single phase. An engineer confirms this during the site assessment.

Do you offer maintenance contracts?

Yes. Essential Care (₦75,000 per year) covers an annual inspection and cleaning; Premium Care (₦150,000 per year) adds a second visit, proactive monitoring and priority response; Commercial Care (from ₦350,000 per year) provides quarterly maintenance and performance reporting for commercial and industrial systems.
