Power4 UPS-BESS / Upstream Oil & Gas

Keep the wells running when the power doesn't.

A battery and UPS-grade system that keeps your site running through the power events that stop production and damage equipment. It sits on the critical-load bus, bridges the transition between power sources, and gives generators time to come online cleanly. The events that damage ESPs and shut in wells stop reaching your equipment.

The real cost of a power event

Most operators know a power failure costs production. Fewer realise the cost is rarely just the production.

On an upstream platform, the true cost depends on what gets damaged in the process, and how remote the site is when it does. A single voltage dip can trip a string of VSD-driven ESPs. The same dip that looks like a momentary blip on the bus can turn into a multi-hour shutdown with damaged equipment downhole.

Direct production loss

USD 5K to 50K per event

Deferred output while the site restarts. One to six hours depending on how badly the event hit. The visible cost, and usually the smallest one.

ESP damage and workover

USD 300K to 1.5M per workover

Run-life lost to power events. 61% of ESP failures are caused by electrical issues. Power failure, under-voltage and voltage unbalance are the most common specific causes. This is where the real money sits.

Reservoir damage

USD 500K to 5M+ per well, per year

Permanent production loss. Up to 25% permanent oil rate loss after an uncontrolled shut-in. Rare, but when it happens it can be permanent. The tail risk that makes the case on its own.

Remote-site multiplier

Every figure above, higher

Rig logistics, parts availability and access time multiply every cost on a hard-to-reach platform. A workover that costs USD 300K in an accessible field can run to USD 1.5M in a remote basin.

How it changes the picture

A clean bridge between power sources.

The Power4 UPS-BESS sits on the critical-load bus and takes over instantly when voltage drops. It carries the load through the transient, smooths the bus so VSDs never see the disturbance, and holds while generators sync and come online cleanly.

In simple terms, it removes most of the events that drive the costs on the left. It is the difference between a momentary blip and a multi-hour shutdown with damaged equipment downhole.

On a site with generator redundancy, the system is not there to replace generation. It bridges the transitions that generators cannot cover fast enough on their own, and it does it every time, in the background.

The economics, in plain terms

What it prevents costs far more than what it costs.

These are published industry figures, in current dollars. Where a site sits on the scale depends on production volume, location and how exposed the equipment is to power-quality events. The pattern is consistent: a single prevented event can outweigh the investment many times over.

USD 5K–50K
Production loss, per event

The frequent cost

Routine restarts after a power event. Happens often, adds up quietly across a year.

USD 300K–1.5M
ESP workover, each

The expensive cost

61% of ESP failures trace to electrical issues. A single avoided workover can outweigh the system on its own.

USD 500K–5M+
Reservoir damage, per well/yr

The catastrophic cost

Permanent rate loss after a bad shut-in. Rare, but when it happens it can be permanent.

A typical upstream platform sees the system pay back in months, not years.

What the system is worth on your platform comes down to the load profile, how often events occur, and what they put at risk downhole. That is the conversation worth having. Tell us about the site and a local representative will work through the numbers that matter for your operation.

What you are getting

Built for industrial-critical loads, not the spreadsheet.

The system shown here can be scaled up or down to suit your site. The same architecture solves the same problem, whether you need more capacity or longer ride-through.

1.5MW
Rated AC power

Carries the full critical load

Sized to take over ESPs, reinjection, gas compression and export pumps without the load seeing the disturbance.

1.51MWh
Usable energy at DC

Hours of headroom

Comfortable bridge for a diesel black start that does not catch first attempt, with capacity to spare on the common cases.

<20ms
On-grid / off-grid switch

Faster than the load reacts

Well inside the ride-through tolerance of VFD-driven ESP and reinjection motors. The transient never propagates.

CATL
LFP cells, 285 Ah

The global leader in cells

Lithium iron phosphate: high thermal stability, no oxygen release under overcharge, long cycle life. Fully certified to UL and IEC standards.

IP56
Outdoor rated

No building required

Liquid-cooled outdoor cabinets and a containerised PCS skid. Deploys on a prepared pad. No external structure needed.

1P
Single-point operation

Three-level BMS, full EMS

Cell, rack and master BMS with integrated fire safety, thermal management and a local monitoring and control layer.

Where it earns its place

Four events your site sees, handled the same way.

The job of the system is not to ride out long outages on its own. It is to bridge the transition between power sources without the load ever knowing.

1

Single genset trip

The most common event. The system bridges from milliseconds to a few minutes while the second generator absorbs full load. Response time is what matters here, and the system has it.

2

Multiple gensets fail

The system carries the full critical load while the diesel black-starts and syncs. That is a matter of seconds to minutes, with comfortable margin behind it if the diesel does not catch first attempt.

3

Voltage and frequency transients

During normal operation the PCS smooths the bus continuously. VSDs never see the disturbance. This is constant background protection, not a one-off.

4

Planned generator maintenance

A generator can be cycled out for service while the system and the remaining unit carry full load. A real operational improvement, not just an emergency backstop.

Sizing is a design conversation for each site. A platform with only one generator and no backup is sized differently to one with redundancy. Our local representatives work through the topology, the critical-load profile and the ride-through tolerance with you before anything is quoted.

Support that stands behind it

You are never on your own with this system.

With Power4 you have factory-direct support: a direct line to the manufacturer and the pool of the leading battery intelligence in the world. That backing reaches your site whichever way suits you.

Straight to your own team

If you run a local expert team, the same factory-level support flows directly to them. Full access, same depth, no layer in between.

A network of local specialists

Support also flows to our network of local specialists and contractors who service the equipment on the ground, close to your operation.

Factory engineer to site

For any major issue, a factory engineer to site is the fallback. The people who built the system are available when it genuinely matters.

All of it backed by dedicated remote monitoring.

The system is overseen through a dedicated remote monitoring program. We see in real time how it is performing, which means most things are understood and acted on before they ever become a problem on your site.
