Utility-Scale BESS · 2 MWh · Liquid-Cooled · 20-ft ISO Container

Utility-Scale BESS — 2 MWh Containerised.

Q: Can the 2 MWh BESS work as the storage component for an IPP solar farm?

Yes. One HLY-BESS-Utility-2MWh container (2,232 kWh) provides the firming buffer for PV farms in the 5–10 MW range, depending on PPA delivery obligations. AI dispatch optimises charge and discharge against irradiance forecasts and day-ahead price signals. Actual buffer sizing depends on PPA terms and TSO balancing rules — contact sales@henleypower.eu with your farm data for a project-specific sizing study.

Q: What cluster size does a wind balancing site need for 2 MWh storage?

One HLY-BESS-Utility-2MWh container (2,232 kWh, 0.5C discharge) covers intra-hour imbalance exposure for wind portfolios in the 5–10 MW range. Dispatch cycle count depends on the wind variability profile — not all sites run at 1C daily duty, so cycle life projection varies by site. Contact sales@henleypower.eu with your wind data for a duty-cycle study.

Q: Is this battery storage suitable for utility substation deferral?

Yes, with conditions. One HLY-BESS-Utility-2MWh covers substation deferral cases in the 2–5 MW peak shaving range. IEC 61850-8-1 substation communication profile is optional — confirmed at contract phase. Warranty insurance via licensed European insurer is available for DFI-financed and institutionally-backed tenders. DNO/TSO grid code approval is required before connection — confirm applicability with your network operator early in the project cycle.

Q: Can the unit operate at high altitude or in coastal environments?

Maximum operating altitude is 4,000 m, with power derating above 2,000 m. For coastal and marine sites, C5 anticorrosion is available as an option (C4 is standard). The −40 °C to +60 °C operating range covers Nordic and Middle East deployments without additional derating, so the platform doesn’t need an external climatic enclosure for those climates.

Q: How does this compare to other 5 MWh BESS containers in the market?

Most 5 MWh containerised BESS in this category cluster around three differentiators: voltage class, temperature range, and warranty jurisdiction. Henley Power operates at 1,331 Vdc — at the high end of the category — which reduces cable cross-sections and balance-of-plant cost per MWh. The −40 °C to +60 °C operating range covers Nordic and Middle East deployments without derating, and contracts are EU-jurisdiction with warranty service delivered from Romania and spare parts stocked in-region. We’re a 2022 manufacturer building toward the deployment scale that established suppliers reach over decades — six or more countries deployed, three or more non-recourse project-finance lenders, one gigawatt-hour shipped on EU-jurisdiction contracts. We’re not there yet, and we say so. Independent technical comparison reports available under NDA.

Q: What certifications are available for project finance?

IEC 62619, IEC 62477-2, IEC 63056, IEC 61000-6-2/4, IEC 62933-5-2, EU Regulation 2023/1542, CE Declaration, UN 38.3, UN 3536. Test reports available under NDA. Full bankability package — including warranty insurance options, manufacturer financial statements, and project references — provided for lender due diligence.

Q: What SCADA and EMS platforms are compatible?

Open protocols, no proprietary lock-in. Modbus TCP, Modbus RTU, CAN, RS485, IEC 60870-5-104, IEC 61850-7-420 (DER) and IEC 61850-8-1 (substation) optional. Compatible with major SCADA platforms including Ignition, OSIsoft PI, ABB Ability, Siemens SINEMA, and GE iFIX. OTA firmware updates via Cloud EMS.

Q: What is the minimum order and lead time?

No enforced minimum — single container orders supported. Standard lead time 35 days from contract signature and deposit receipt to factory dispatch. Track record: utility ESS deployments across Inner Mongolia, Ningxia, Shandong, Hebei, and Henan provinces in China, plus a PV-storage-diesel microgrid in Chad. First European delivery is the Moldova 10 MWh first tranche of a 150 MWh pipeline, scheduled Q2 2026. Project references and customer letters available under NDA.

Q: What service response can we expect?

Diagnostic response within 1 hour via remote O&M. Solution path within 24 hours, including on-site dispatch where required. Service centres in Europe, Africa, East Asia, and Central Asia. Spare parts stocked in-region for primary markets. Service-level agreement scope confirmed per project at contract phase.

Application scenarios

Six utility buyer verticals deployed.

Each vertical sizing example below assumes typical European project load profiles and grid code requirements. Final sizing depends on metered data, dispatch duty cycle, and TSO qualification scope.

IPP Solar Farms

Co-located battery energy storage for IPP developers firming PV output against PPA delivery commitments. One HLY-BESS-Utility-2MWh container covers farms in the 5–10 MW range. AI dispatch optimises charge and discharge against irradiance forecasts. Curtailment penalty exposure depends on your PPA terms — we’ll confirm that at contract phase.

Wind Balancing Sites

Storage buffer for wind portfolios in the 5–10 MW range, absorbing excess generation and releasing during lulls. A single HLY-BESS-Utility-2MWh handles intra-hour imbalance under European TSO balancing rules. Dispatch cycle count depends on your wind variability profile — it’s not a fixed daily number.

Utility Substations

Grid-connected storage at HV/MV substation level for peak shaving and N-1 contingency support. One HLY-BESS-Utility-2MWh handles deferral cases in the 2–5 MW peak range. IEC 61850-8-1 substation comms profile is optional. DNO/TSO approval is required — don’t leave this to the last month of commissioning.

Grid-Forming Sites

BESS in grid-forming mode provides synthetic inertia and voltage control for low-inertia grids. PCS response ≤20 ms enables FCR-N, FCR-D, and FFR market participation. ENTSO-E compatible; specific TSO qualification is confirmed per project at commissioning. Grid-forming inverter pairing confirmed at contract phase.

Large Industrial Parks

Demand-charge management for multi-tenant industrial parks with aggregate peak loads of 2–5 MW. One HLY-BESS-Utility-2MWh handles demand charges for parks drawing 2–4 MW peak. Charge during off-peak tariff windows, discharge at site peak. Payback depends on local ToU tariff spread — there’s no universal answer.

Data Centre Campuses

Backup power and demand management for mid-size data centres with critical uptime requirements. A 2,232 kWh BESS operates in parallel with UPS infrastructure for peak shaving. Doesn’t replace full N+1 diesel backup without project-specific study. Integration with BMS/DCIM platform confirmed at contract phase.

Frequently asked questions

Questions from engineers, developers, and lenders.

Can the 2 MWh BESS work as the storage component for an IPP solar farm?

Yes. One HLY-BESS-Utility-2MWh container (2,232 kWh) provides the firming buffer for PV farms in the 5–10 MW range, depending on PPA delivery obligations. AI dispatch optimises charge and discharge against irradiance forecasts and day-ahead price signals. Actual buffer sizing depends on PPA terms and TSO balancing rules — contact sales@henleypower.eu with your farm data for a project-specific sizing study.

What cluster size does a wind balancing site need for 2 MWh storage?

One HLY-BESS-Utility-2MWh container (2,232 kWh, 0.5C discharge) covers intra-hour imbalance exposure for wind portfolios in the 5–10 MW range. Dispatch cycle count depends on the wind variability profile — not all sites run at 1C daily duty, so cycle life projection varies by site. Contact sales@henleypower.eu with your wind data for a duty-cycle study.

Is this battery storage suitable for utility substation deferral?

Yes, with conditions. One HLY-BESS-Utility-2MWh covers substation deferral cases in the 2–5 MW peak shaving range. IEC 61850-8-1 substation communication profile is optional — confirmed at contract phase. Warranty insurance via licensed European insurer is available for DFI-financed and institutionally-backed tenders. DNO/TSO grid code approval is required before connection — confirm applicability with your network operator early in the project cycle.

Which battery cells are used, and how is the choice made?

Tier-1 LFP cells from publicly listed manufacturers, multi-supplier homologated. Cell selection is determined per project at contract phase based on availability, certification requirements of the deployment market, and optional customer specification. Project-specific cell certificates and test reports issued at delivery for lender due diligence. Specific supplier identification shared on request after a mutual NDA.

Can the unit operate at high altitude or in coastal environments?

Maximum operating altitude is 4,000 m, with power derating above 2,000 m. For coastal and marine sites, C5 anticorrosion is available as an option (C4 is standard). The −40 °C to +60 °C operating range covers Nordic and Middle East deployments without additional derating, so the platform doesn’t need an external climatic enclosure for those climates.

How does this compare to other 5 MWh BESS containers in the market?

Most 5 MWh containerised BESS in this category cluster around three differentiators: voltage class, temperature range, and warranty jurisdiction. Henley Power operates at 1,331 Vdc — at the high end of the category — which reduces cable cross-sections and balance-of-plant cost per MWh. The −40 °C to +60 °C operating range covers Nordic and Middle East deployments without derating, and contracts are EU-jurisdiction with warranty service delivered from Romania and spare parts stocked in-region. We’re a 2022 manufacturer building toward the deployment scale that established suppliers reach over decades — six or more countries deployed, three or more non-recourse project-finance lenders, one gigawatt-hour shipped on EU-jurisdiction contracts. We’re not there yet, and we say so. Independent technical comparison reports available under NDA.

What certifications are available for project finance?

IEC 62619, IEC 62477-2, IEC 63056, IEC 61000-6-2/4, IEC 62933-5-2, EU Regulation 2023/1542, CE Declaration, UN 38.3, UN 3536. Test reports available under NDA. Full bankability package — including warranty insurance options, manufacturer financial statements, and project references — provided for lender due diligence.

What SCADA and EMS platforms are compatible?

Open protocols, no proprietary lock-in. Modbus TCP, Modbus RTU, CAN, RS485, IEC 60870-5-104, IEC 61850-7-420 (DER) and IEC 61850-8-1 (substation) optional. Compatible with major SCADA platforms including Ignition, OSIsoft PI, ABB Ability, Siemens SINEMA, and GE iFIX. OTA firmware updates via Cloud EMS.

What is the minimum order and lead time?

No enforced minimum — single container orders supported. Standard lead time 35 days from contract signature and deposit receipt to factory dispatch. Track record: utility ESS deployments across Inner Mongolia, Ningxia, Shandong, Hebei, and Henan provinces in China, plus a PV-storage-diesel microgrid in Chad. First European delivery is the Moldova 10 MWh first tranche of a 150 MWh pipeline, scheduled Q2 2026. Project references and customer letters available under NDA.
