Case Study · Commercial Energy & EPC Delivery
Turnkey Energy Infrastructure for Australian Industry
From a 250 kW rooftop system to a 50 MW behind-the-meter microgrid, ESQ Energy Solutions delivers commercial energy projects as a single accountable partner. DC System Services built the capability page that communicates that offer to Australia's most energy-intensive operators.
Engineered, financed, and operated.
One engagement model, transmission-scale delivery
Project size, service life, and reliability commitments that off-the-shelf installers can't match.

The model
One Partner. Every Phase. No Gaps in Accountability.
Most commercial energy projects fail not because of bad engineering, but because accountability is split across too many parties — the EPC contractor hands off to finance, who hand off to a connection consultant, who hand off to an O&M provider, and every boundary is a risk. ESQ eliminates those boundaries. As a single accountable partner it absorbs the engineering risk, sequences all trades, manages the network operator, structures the finance, and operates the asset for its full service life — available under CAPEX, PPA, lease, or Energy Services Agreement.
Capability
Six Practices. One Delivery Team.
Engineering, Procurement & Construction
Full EPC delivery with in-house electrical, structural, and grid engineers — single-source accountability from design to commissioning across solar, storage, EV, and hybrid systems.
Microgrids & Energy Infrastructure
Islanding-capable hybrid systems integrating solar, battery, gas or diesel generation, and controllable loads — built for resilience in remote, industrial, and critical-facility environments.
Grid Connection & HV Works
Substations, ring main units, switchgear, protection coordination, and DNSP/TNSP approvals up to 66 kV — ESQ holds the network operator relationship end to end.
Power Purchase Agreements
Behind-the-meter PPAs with zero CAPEX outlay. ESQ funds, builds, owns, and operates the asset; clients pay only for the energy consumed while transferring performance risk.
Energy Management & Metering
NMI-compliant metering, sub-metering, AEMO market participation, and SCADA-grade dispatch managed from ESQ's Brisbane Network Operations Centre.
Operations & Maintenance
25-year performance guarantees backed by national service crews, parts pooling, and remote diagnostics — a contractual availability SLA, not a best-efforts commitment.
Who this is for
Where Energy Is a Material Operating Cost or Risk
ESQ's commercial practice is built for operators where electricity is not a minor line item — heavy industrial and manufacturing facilities with punishing demand tariffs, logistics and cold chain operators running 24/7 refrigeration, resources and remote sites beyond reliable grid reach, healthcare and data centres where continuity is non-negotiable, education and government campuses with long asset horizons, and property developers embedding energy infrastructure into asset valuations. The common thread is scale and complexity — projects where a single-trade contractor is the wrong answer.
The delivery process
Four Stages. No Skipped Steps.
Discover
Energy audit, tariff analysis, and decarbonisation pathway mapping — where the business case is built and the technical scope is defined.
Design
EPC scope, finance structure selection, network connection applications, and engineering sign-off by RPEQ-registered electrical and structural engineers.
Build
Procurement, civil works, electrical installation, HV construction, and full commissioning — all trades sequenced and supervised by ESQ.
Optimise
Live performance management, AEMO market participation where applicable, quarterly reporting, and ongoing O&M under the contracted availability SLA.
The finance options
The Structure That Fits Your Balance Sheet
Four ways to engage — matched to your capital position, from full ownership to an outcome-based savings contract.
CAPEX
Direct purchase. Full ownership from day one and maximum long-term return.
Power Purchase Agreement
Zero upfront cost. ESQ owns and operates the asset; you pay per kilowatt-hour at a contracted rate below your current tariff.
Lease
Structured asset finance with fixed monthly payments and a clear end-of-term position.
Energy Services Agreement
An outcome-based contract tied to measured energy savings rather than energy volume.
The takeaway
A Commercial Energy Project Worth Doing Is Worth Engineering Properly
From the design table to 25 years of operations.
ESQ Energy Solutions delivers turnkey commercial energy infrastructure across Australia. DC System Services built that capability into a digital presence that converts energy-intensive operators into qualified project enquiries.
