Solar & Storage Live 2026: what we heard, and what it means if you own the equipment
Six talks at Solar & Storage Live UK 2026 on storage, data centres, grid connections, solar O&M and decommissioning, and what each means for owners.
Medium voltage or low voltage UPS? How to tell which fits your site
Most UPS conversations start at low voltage. For sites measured in megawatts, a medium voltage UPS protecting the whole network can beat rack by rack.
The certifications energy tenders ask for, and what each one means
ISO 9001, Cyber Essentials, UL, CSA: energy tenders list required certifications up front, and missing one can bar you from bidding. What each means.
Medium voltage UPS repair, refurbishment and service
Repair, refurbishment and service for medium voltage and large low voltage UPS systems: batteries, power modules, controls, cooling. UK and US workshops.
Arc flash studies for solar, wind and battery storage sites
What an arc flash study is, what it produces, when UK and US rules expect one, and why operators with many sites have them done by a specialist.
Why a bigger grid connection for electrification takes so long
Switching a site from gas or diesel to electricity means a bigger grid connection. What the network asks for, the studies involved and where the time goes.
Which parts go obsolete inside a working power system, and the fixes
A UPS, STATCOM or battery system can be stopped by one discontinued part. What fails first, and the repair, redesign and upgrade routes that fix it.
S&C PureWave DSTATCOM, UPS and AVC: spares, repair and upgrades
S&C stopped building the PureWave line in 2018. RE&D owns the technology and supports every installed unit: spares, board repair, upgrades, on-site rebuilds.
STATCOM repair and service, from spares to on-site rebuilds
STATCOM repair, maintenance, spares and control upgrades for units the maker no longer supports. UK and US workshops, on-site rebuilds, service contracts.
Transformer and switchgear lead times, and how to work around them
Large power transformers now quote lead times past 120 weeks, with prices up 77% since 2019. Why refurbishing existing equipment is often the faster path.
Grid connection queue delays: when is a private wire the better answer?
Britain's reformed connection queue has admitted 62% of protected projects will miss their dates. For some sites, a private wire is the faster answer.
What a CCP5 to CCP9 STATCOM control platform upgrade involves
The CCP board is the brain of a STATCOM, and the older generation is now unsupported. What the CCP5 to CCP9 upgrade involves, and the spare board trap.
A STATCOM control upgrade keeps a working asset off the scrap list
The power hardware in a STATCOM outlives its control system by decades. How a control platform upgrade saves a working asset from the scrap quote.
Severn Drives & Energy at Solar & Storage Live UK 2026
Severn Drives & Energy exhibited at Solar & Storage Live UK 2026, NEC Birmingham, 22 to 24 September. Read what we heard at the show and how to get in touch.
Kokam battery replacement: what to do now that support is gone
Kokam battery modules are obsolete and manufacturer support is gone. What replacement actually requires, and how we verified a working option.
Rebuilding a burned-out DSTATCOM inverter on site
An arc fault destroyed a DSTATCOM inverter section. Instead of shipping it to a factory, we rebuilt it on site from the drawings up. How the job was done.
What is a private wire? Connecting local generation directly to local demand
A private wire takes a generator's power straight to a nearby user. How private wire networks and private grids work, what they need, and who builds them.
Buying a solar farm? The studies worth redoing before you sign
When a solar farm is sold, the new owner inherits its paperwork, warts and all. The technical studies worth redoing before and after you buy a site.
How a power quality root cause analysis finds the real fault
Transformers kept failing and everyone blamed the newest equipment. High-sampling power quality analysis settled it. How root cause investigations work.
Choosing Outsourced Grid Connection Engineering Support
How to choose outsourced grid connection and grid integration engineering support — what “best” actually means for BESS, renewables, and industrial loads, and which capabilities separate real consultants from form-fillers.
Leading Grid Connection Engineering Options for UK Energy Projects
What a UK energy project needs from grid connection engineering: the G99 application, DNO and NESO steps, the studies, and how to choose a partner.
Why Energy Projects Struggle with Grid Connection Engineering
Grid connection projects run late when studies, protection design and compliance work are scoped separately or started late. The causes and the fixes.
Grid Connection Engineering for Battery Storage (BESS) Projects
Grid connection services for battery storage: the studies, grid code checks and storage sizing a BESS project needs before the network will connect it.
Protection Coordination Compliance for Grid Integration
Protection coordination compliance means proving relays and breakers clear faults selectively, within the network operator's limits. What it involves.
How a battery storage project gets its grid connection, step by step
The grid connection process for a battery storage project, from feasibility and application through studies, compliance and energisation, step by step.
What Is Protection Coordination in Grid Integration?
Protection coordination sets relays, fuses and breakers so only the device nearest a fault trips. What it is, how it is done and which standards apply.
Utility-Scale Solar + BESS: Five Integration Challenges We Solve
Solar with battery storage hits five recurring integration problems, from interconnection studies to IEEE 2800 compliance. What each is and how we fix it.
STATCOM vs. SVC: How We Choose the Right Dynamic Reactive Support
STATCOM vs SVC compared: how each one works, response time, behaviour in a voltage dip, cost per kVAr, cooling, and which one suits your site.
What harmonic filters do, and when your site needs one
Harmonics overheat motors, trip drives and shorten equipment life. How passive and active harmonic filters work and keep a site within IEEE 519 limits.
How the grid stays resilient as renewables take over
More renewables and more extreme weather put grid reliability under strain. How battery storage, grid upgrades and microgrids keep supply stable.
What is a STATCOM, and how does it keep grid voltage steady?
A STATCOM injects or absorbs reactive power within milliseconds to hold grid voltage steady. How it works, where it is used and how it compares with SVCs.
What an uninterruptible power supply does and when you need one
An uninterruptible power supply keeps critical equipment running when the mains fails or dips. How a UPS works, the main types, and who needs one.
Poor power quality costs more than the odd breaker trip
Breaker trips are the visible part. Poor power quality also shows up as stalled machines, failing equipment and higher bills. What to measure and fix.
Why voltage sags trip your drives, and how a DSTATCOM stops them
A voltage sag of a fraction of a second can trip a drive and halt a production line. What causes sags, what they cost and how a DSTATCOM corrects them.
