As state utilities across the Middle East accelerate multi-gigawatt solar integration and pioneer green hydrogen megaprojects, grid reliability hinges on bankable, utility-scale energy storage.
In an exclusive interview with OGN energy magazine, Jack Chen, Head of Energy Storage, MEA Region at Trinasolar, outlines how its integrated DC+AC architecture addresses the region’s strict commissioning timelines and demanding operational conditions.
From maintaining cell-to-cell temperature variations under 2.5 deg C in extreme 50 deg C desert heat to delivering sub-10-millisecond grid-forming responses, Trinasolar’s engineering strategy balances active cooling parasitic loads against long-term lifecycle economics.
By executing complete factory-level testing, keeping cell supply-chain traceability in-house, and deploying localised engineering support across MEA, Trinasolar offers developers a blueprint to mitigate execution risk, lower LCOS, and future-proof battery assets for emerging long-duration and high-frequency regulation markets.
Below are excerpts from the interview:
As state utilities in Saudi Arabia and the UAE scale up multi-gigawatt solar assets, what operational boundary determines whether developers choose fully integrated DC+AC packages over modular, multi-vendor BESS architectures?
Integrated systems minimise deployment and operational risk through single-vendor accountability, while modular approaches favour technology flexibility.
The right choice tends to come down to a developer’s risk tolerance, procurement strategy, and in-house operational expertise.
For the multi-gigawatt state utility programmes scaling up across Saudi Arabia and the UAE, that trade-off tends to favour integration.
At that scale, coordinating multiple vendors across DC and AC scopes multiplies interface risk and adds time to an already tight commissioning schedule, the specific problem Elementa + Electra was built to remove.
The platform combines the Elementa 3 DC battery system with the 13.8-MVA Electra AC platform as a single, factory-tested package, delivering up to 50-MWh of storage capacity with configurable 2-8 hour durations.
Because the DC and AC sides are engineered and tested together rather than integrated on-site, the system achieves up to 96 per cent full-chain efficiency, while containerised transport and factory-level testing cut commissioning time by up to 50 per cent.

Considering green hydrogen megaprojects in Oman and Saudi Arabia, what is the economic calculus of deploying multi-gigawatt LFP storage for electrolyser capacity factors versus grid-supplied power?
LDES is a key enabler for multi-GW green hydrogen projects in Oman and Saudi Arabia, where large solar and wind portfolios must be combined to deliver a higher and more stable electrolyser capacity factor.
Elementa supports configurable multi-hour storage, enabling surplus renewable generation to be shifted across extended periods and reducing reliance on grid-supplied power.
At plant level, Trina BESS can firm the combined solar-wind profile, manage intermittency and ramping, and maintain electrolyser loading during renewable shortfalls.
This allows developers to increase renewable utilisation and electrolyser operating hours while maintaining the low-carbon credentials of hydrogen production to optimise the balance between renewable oversizing, storage duration, electrolyser capacity factor and grid dependency, ultimately targeting a lower LCOH.
How does Trina Storage intend to capture long-duration storage market share in MEA if 4-hour LFP economics hit a ceiling against emerging alternative chemistries?
Trina Storage’s strategy for long-duration storage is to extend the capability of proven LFP technology while maintaining flexibility for future chemistry evolution.
The Elementa platform supports configurable 2-8 hour durations, enabling Trina to address emerging LDES applications in MEA without requiring developers to immediately transition to less mature storage technologies.
For 6-8 hour applications, system optimisation, high-energy-density cells, liquid cooling and lifecycle management can continue to improve LFP economics at plant level.
Beyond this range, Trina Storage will evaluate technology based on LCOS, safety, bankability, degradation and regional operating conditions, rather than chemistry alone, retaining a technology roadmap capable of integrating next-generation chemistries as they become commercially bankable.

What are the primary supply chain and logistical bottlenecks currently delaying utility-scale BESS grid synchronisation across the Middle East?
Two bottlenecks stand out in the region right now: The first is a shortage of qualified system integrators and BESS-experienced engineers, which tends to stretch out on-site execution timelines.
We ship the DC and AC sides in containerised form and complete factory-level testing before anything leaves the plant, so most integration work happens off-site.
At the 300-MWh Abydos BESS in Egypt, where we were the exclusive energy storage partner, the system was installed and connected to the grid in just 60 days.
The second is supplier qualification for battery traceability systems; onboarding a third-party vendor can take 6 to 12 months, pushing back commissioning before construction even starts.
We keep traceability in-house: Our manufacturing execution system tracks every battery cell across more than 2,100 process checkpoints, generating upwards of 15 production traceability reports per project.
How does Electra achieve 10 ms full-power response with synthetic inertia and grid-forming capability, given complex local grid protocols?
It delivers full-power response in as fast as 10 ms, with fast active and reactive power control supporting grid-forming, grid-following, voltage/frequency regulation, synthetic inertia and black-start capability.
These critical dynamic functions are executed locally at the PCS level, independent of slower plant-level commands.
For system integration, Electra provides native IEC 61850 and Modbus TCP communication with EMS/PPC, enabling high-speed plant coordination and adaptation to different utility control architectures.
How does Trinasolar guarantee cell-to-cell temperature variation under 2.5 deg C in desert heat exceeding 50 deg C?
Elementa + Electra uses a three-tier, vein-bionic liquid cooling system engineered specifically to hold cell temperature variation at ≤2.5 deg C.
Rather than running fixed cooling parameters, the system uses a self-developed decision-making programme that continuously monitors each cell’s real-time thermal field and adjusts coolant temperature and operating mode accordingly.
The platform is rated for -35 deg C to 55 deg C ambient operation, and the Elementa series has completed operational validation in extreme environments including harsh dessert conditions.

What specific auxiliary power overhead is required to run active liquid cooling in high-heat GCC environments, and how does that parasitic load impact overall levelised cost of storage calculations?
For GCC applications, Trina Storage optimises liquid-cooling auxiliary consumption against battery lifetime rather than simply minimising HVAC power.
Verified field auxiliary consumption has been demonstrated as low as 1.8 per cent.
From an LCOS perspective, cooling represents a parasitic energy cost, but effective thermal management improves usable energy throughput, round-trip efficiency and capacity retention over the project life.
Therefore, the economic benefit is evaluated on a lifecycle basis, auxiliary energy consumed versus degradation avoided and additional lifetime MWh delivered.
How does Trinasolar adapt its cell degradation guarantees to protect developer revenue models against harsh cycling profiles for frequency regulation?
Trina Storage addresses high-cycling applications by aligning cell capability, degradation modelling and operating strategy with the project’s actual duty cycle.
For frequency regulation, Trina evaluates the expected cycling profile, depth of discharge, C-rate, temperature and energy throughput when defining the system operating envelope and long-term performance commitments.
This is supported by Trina’s in-house cell technology, with the latest 314 Ah cell designed for up to 15,000 cycles, together with intelligent BMS and thermal management that control SOC, temperature and cell-to-cell variation to limit accelerated ageing.
Independently verified field data showing 98 per cent usable-capacity retention after more than one year of operation further demonstrates the platform’s degradation performance.
What fire safety architecture and thermal runaway propagation safeguards are built into Elementa for regional civil defence standards?
Elementa incorporates a certified, standards-driven fire-safety architecture from cell to system level. At cell level, UL 9540A validates thermal runaway behaviour, while UL 94-5VA flame-retardant pack covers provide an additional passive protection layer.
Rack/system-level UL 9540A testing verifies resistance to thermal runaway propagation.
At container level, the fire protection architecture is designed and certified to NFPA 13 for sprinkler protection, NFPA 68 for deflagration venting, NFPA 69 for explosion prevention and combustible-gas management, and NFPA 72 for fire detection and alarm.
The overall BESS installation and fire-safety design complies with NFPA 855 requirements.
With national localisation mandates, such as Saudi Arabia’s iktva and the UAE’s In-Country Value programmes expanding, what concrete commitments is Trina Storage making toward regional assembly, system integration, or localised engineering support?
Our commitment on the ground is built around system integration and long-term engineering support rather than a fly-in, fly-out model.
Across MEA, we work with established distributors, EPCs, and service partners who provide on-the-ground engineering support, installation, commissioning, and long-term operations and maintenance backed by a global network of 31 service centres and 230+ service engineers across 100+ countries and regions.
