Keep critical operations running
Support selected loads when the grid fails, within the designed power and energy capacity.
BUSINESS & INDUSTRIAL ENERGY STORAGE
Store power.
Protect productivity.
BESS helps businesses use energy more intelligently, protect selected operations and get more value from solar. The right solution begins with your load data and business objective, not a standard battery size.WHY BUSINESSES CONSIDER BESS
Electricity is an operating input.
Continuity is a business outcome.
A battery is valuable only when it solves a defined problem. For one site that may be production continuity. For another it may be peak management, better solar utilisation or preparation for future expansion.
Reduce costly demand peaks
Discharge strategically when site demand is high, subject to the tariff and operating profile.
Use more of your solar
Store suitable surplus generation for later instead of relying only on real-time solar use.
Build operational flexibility
Create a controllable energy asset that can respond to changing loads and business priorities.
Important reality checkBESS does not create energy, guarantee savings or provide unlimited backup. Its value depends on the site load, tariff, solar profile, operating strategy, usable capacity and engineering.
BESS IN DAILY BUSINESS
See the operating problem.
Then consider storage.
Protect the process, not necessarily the whole plant
Keep PLCs, controls, servers, emergency systems or selected machinery operating while non-critical loads remain off.
Possible value: less disruption, scrap and restart timeCoordinate fast battery response with longer backup
A battery may bridge short interruptions or reduce unnecessary generator starts. Longer outages can still be supported by the generator.
Possible value: smoother continuity and lower generator useMove suitable solar energy to a later operating period
When solar generation exceeds useful daytime demand, storage may make part of that energy available later.
Possible value: improved solar utilisationSupport repeatable peaks instead of the entire daily load
Interval data can reveal whether a controlled battery discharge may help manage short high-demand periods.
Possible value: tariff-dependent demand managementOFFICIAL TATA POWER BATTERY STORAGE RANGE

Question 1 of 6
THREE COMMON STARTING POINTS
New system or retrofit.
One objective-led approach.
Storage can be planned with new solar, retrofitted around an existing plant or assessed independently. Each route has different integration questions.
Solar already installed
Review generation, export, inverter arrangement, protections and the load profile before deciding how storage should connect.
- ✓ Use suitable surplus solar later
- ✓ Add selected-load resilience
- ✓ Avoid assuming every solar system is battery-ready
Solar and BESS together
Design the solar array, battery, inverter, controls and operating modes as one coordinated energy system.
- ✓ Coordinate present and future capacity
- ✓ Plan critical-load separation early
- ✓ Compare integrated lifecycle value
BESS without solar
Use storage for resilience or load management where the tariff and operating pattern support a clear case.
- ✓ Assess charging source and tariff
- ✓ Measure demand peaks accurately
- ✓ Keep future solar integration in view
HOW BESS WORKS
Four parts working
as one energy system.
Energy source
Grid, solar or another approved source charges the system.
→Battery
Stores a defined amount of usable energy, measured in kWh.
→PCS and controls
Manage charging, discharge, power flow and operating priorities.
→Business loads
Receive power according to the selected mode and system limits.
How much equipment the system can support at the same time.
How much usable energy is available and, together with the load, how long it may run.
When the battery charges, when it discharges and what the system prioritises.
One system. Multiple coordinated sources.
Charged by solar. Backed by the grid. Ready for you.
Captures and stores excess solar energy for optimal useSeamlessly charges from the grid when solar isn’t availableSmartly balances power between solar and gridEnsures uninterrupted power, day and night
One system. Multiple advantages. Complete control.WHERE VALUE CAN COME FROM
Different sites.
Different value stacks.
More than one use case may be possible, but they can compete for the same stored energy. The operating strategy must decide what takes priority.
Power continuity
Keep chosen production, process, IT, lighting or safety loads available through short grid interruptions.
Best when downtime has a measurable business cost.Solar shifting
Charge from available solar and use that energy later, based on the system design and operating strategy.
Best when solar production and consumption occur at different times.Peak management
Support the site during selected high-demand periods to help manage demand-related costs.
Best when interval data shows short, repeatable peaks.Power quality support
A suitably engineered system may support voltage, frequency or transition requirements for selected loads.
Requires detailed electrical and load assessment.BUILD THE BUSINESS CASE
Measure value beyond
the battery price.
A responsible feasibility study separates measurable financial benefits from resilience benefits. It also tests whether those benefits can occur together without compromising the backup reserve.
Avoided downtime
Estimate lost output, wasted material, restart time, delayed orders and labour impact from a typical outage.
Ask: What does one hour of interruption cost?Generator impact
Review fuel, servicing, low-load operation, start frequency and the outages that still require longer generator support.
Ask: Which generator runs could storage realistically avoid?Solar utilisation
Compare solar generation, export and consumption by time of day before assigning savings to a battery.
Ask: Is usable solar regularly available to charge it?Tariff opportunity
Use interval demand and the applicable tariff to evaluate peak management or time-related energy value.
Ask: Does the tariff reward the intended operating strategy?Commercial decision rule
Proceed only when the proposed operating strategy, measurable benefits, resilience value, lifecycle cost and technical constraints are understood together.
RIGHT-SIZE THE INVESTMENT
Battery sizing is not
one multiplication.
A dependable design separates power, energy, outage expectations and commercial operation. Oversizing can weaken the business case. Undersizing can disappoint during real operation.
Preliminary planning toolEstimate selected-load backup using familiar equipment. Commercial motors, three-phase loads and process equipment require an engineer-led study.
ESTIMATE SELECTED-LOAD BACKUP →Define critical loads
Which machines and systems must continue, and which can stop?
Measure simultaneous power
What must run together, including starting current and expansion headroom?
Set the backup window
Minutes for safe shutdown, hours of continuity or support until a generator starts?
Study energy data
Bills, interval demand, solar generation, export and outage history.
Model operating modes
Backup reserve, solar charging, peak control and recharge priorities.
Validate the site
Space, temperature, fire safety, access, electrical integration and approvals.
WHAT A GOOD PROPOSAL SHOULD SHOW
Compare the complete system.
Not only the battery price.
✓ Usable kWh and rated kW✓ Battery chemistry and operating limits✓ Expected operating modes✓ Round-trip efficiency assumptions✓ Cycle and calendar-life assumptions✓ Warranty terms and exclusions✓ PCS, EMS and monitoring scope✓ Electrical protection and isolation✓ Thermal management and enclosure✓ Fire detection and safety approach✓ Installation and commissioning scope✓ Service response and maintenance plan
Final design, standards, approvals and safety provisions must be selected for the specific site, capacity, equipment and applicable regulations.
SAFETY, MONITORING & SUPPORT
A battery is infrastructure.
Lifecycle support matters.
Site-specific safety
Electrical protection, isolation, enclosure, access, thermal management, detection and emergency response must suit the selected system and site.
Monitoring and controls
Track system status, alarms, power flow, state of charge and operating performance through the agreed monitoring scope.
Clear documentation
Receive operating modes, settings, warranties, drawings, commissioning records, emergency procedures and maintenance requirements.
Defined responsibilities
Clarify remote support, preventive maintenance, response arrangements, spare parts and responsibilities across suppliers.
BUSINESS OWNER QUESTIONS
Clear answers before
you invest.
Not automatically. A practical design normally prioritises critical loads. The battery power rating, stored energy, starting currents, operating sequence and required backup duration must all be checked.
