Powering Reliability: How Advanced Analytics Strengthens BESS Availability 

Battery Energy Storage Systems (BESS) have quietly become one of the most critical pieces of the modern energy puzzle. Whether it’s to balance renewables, support the grid or meet peak demand, batteries deliver power exactly when it’s needed. 

But there’s a catch. Even the most advanced BESS isn’t useful if it isn’t fully available.  Downtime — whether it’s a single rack or an entire block — directly impacts energy delivery, market participation and ultimately – your revenue.  This makes availability analytics essential for BESS owners. 

At Quadrical, we’ve spent 3 + years working with 6 + GWh of BESS.   One thing is clear — availability isn’t about a single number on a dashboard.  It’s about understanding what’s happening under the hood. 

Seeing Beyond Uptime : Traditional monitoring tells you when an asset is running or has hit a snab.  Useful, yes — but not enough. Modern storage sites are complex.  A tiny fault at the cell or inverter level can cascade into larger availability losses. 

Our Availability Analytics platform breaks down performance at multiple levels — plant, inverter, rack, string — so you can pinpoint exactly when & where availability slipped.  Instead of chasing alarms across multiple systems, you get one clear view of what’s working, what’s not and most importantly, what the problem is most likely to be – clearly spelled out. 

From Fault-to-their Tickets: Making Faults Actionable : One of the biggest pain points in asset operations is fault management. A fault pops up, someone logs a ticket, and then… it often becomes a long chase to find root cause. 

We wanted to make this process faster and clearer – so the Quadrical platform connects the dots. 

Detect: Each fault is automatically captured with location, timestamp and severity. 

Correlate: It’s then mapped to any availability drop it caused. 

Ticket: That fault is directly linked to a maintenance ticket. 

Learn: Recurring faults are flagged, so chronic issues are identified early. 

The result?  Operators spend less time digging through SCADA logs and more time actually solving the problem. 

Prioritizing What Truly Matters : Not all faults are equal.  Some shave off a few kWh, others take down entire blocks.  Our system ranks events by impact — energy lost, severity, and recurrence.  That makes it easy for O&M teams to focus where it counts. 

This isn’t just about improving response times.  It’s about creating a more intelligent, structured way to manage faults, keeping your assets online and productive the most amount of time possible. 

Turning Availability Into Real Value : Every percentage point of availability matters.  The more your asset is up and running – the more energy you deliver and thus the more value you create.  Better fault visibility means fewer surprises, faster fixes and higher confidence in performance forecasts.  Over the years, with more than 6000 MWh of BESS on our platform, strong availability = strong revenue is the simple truth we’ve seen play out again and again. 

A Smarter Way Forward : As storage portfolios grow, manual fault tracking won’t stand a chance.  You will need tools that go beyond simple alerting to guide — from fault to resolution.  That’s exactly what we built Availability Analytics for. 

Not just software – we at Quadrical are a smarter, more reliable way to run energy storage.  After all the future of energy won’t just need building – it will need you to maintain, monitor, analyze and optimize.  We at Quadrical will be there to help you do just that.
