What does your operation need to improve?
A supply problem can become an operating cost problem. Follow a common sequence, then explore the challenge that matters most at your site.
Supply interruption
Grid instability
An interruption changes the operating conditions. Identify the frequency, duration and quality of supply before selecting a backup system.
Explore this business challengeOperational impact
Production disruption
Stopped lines, process restarts and temperature excursions can matter more than the electricity bill. Define which loads must remain available.
Explore this business challengeBackup response
Diesel use
Generators can restore selected supply, but duty cycle, fuel use, maintenance and coordination determine the operating cost.
Explore this business challengeCommercial effect
OPEX & emissions
Compare fuel, restarts, maintenance and energy use together. Evaluate operational emissions using verified fuel consumption and the applicable emission factors.
Explore this business challengeGRID-DEPENDENT OPERATION
A loss of supply interrupts the process.
Response depends on the available backup and operating procedure.
COORDINATED BACKUP STRATEGY
Priorities and transitions are designed in advance.
Continuity depends on verified transfer performance, reserve and protection settings.

Consultancy
Energy & Power Consultancy for facilities and infrastructure in Bangladesh. Start with evidence, compare options and make assumptions visible.
Explore ConsultancyINTEGRATED ENERGY ARCHITECTURE
One facility. Multiple sources. One coordinated strategy.
SELECT A COMPONENT
Grid
Normal supply and connection point. During an outage, a suitably designed islanding scheme must separate the facility from the grid.
OPERATING SCENARIO
Grid and available solar serve facility demand. BESS follows the defined reserve and scheduling strategy; the generator is normally on standby.
Communications and switchgear integration
Define the device interface schedule, metering points, breaker status, permissives, interlocks and synchronization logic. Assess device-supported Modbus TCP/RTU or IEC 61850 interfaces where appropriate; support and gateway compatibility must be confirmed for the selected equipment.
Conceptual architecture, not a construction single-line diagram. Highlighted lines indicate possible energy paths, not measured output. Protection, islanding, earthing, synchronization and transfer performance require project-specific engineering.
BUSINESS VALUE
Focus on the outcomes that matter
Bills + load profile → options → lifecycle comparison
Lower energy costs
Understand where energy is used, then test the interventions that can reduce avoidable spend.
Explore an energy-cost scenarioOutage profile → critical loads → coordinated backup
Reduced diesel dependence
Target the generator duties that storage or renewable energy can realistically replace.
Explore backup optionsCritical process → transfer requirement → acceptance criteria
Improved uptime
Match the system to the interruption tolerance of your most important processes.
Define the continuity requirementSource diversity → reserve strategy → recovery plan
Greater resilience
Plan for short interruptions, long outages and recovery with explicit load priorities.
Explore hybrid powerGeneration profile → self-consumption → storage duty
More useful renewables
Align generation with the demand it can serve and assess storage when surplus has later value.
Explore solar + storageCAPEX + operation + replacement → lifecycle decision
Better lifecycle economics
Compare losses, support, replacements and maintainability alongside initial equipment cost.

ENGINEERING SCREENING
Explore a first-pass project estimate
Enter site data and your own commercial assumptions. Outputs update as inputs become valid; use Calculate Estimate for a deliberate refresh.
All calculations are indicative baseline estimates subject to detailed on-site power quality logging and engineering validation.
Industrial solar feasibility
Screen rooftop capacity, annual self-consumption value and indicative installed cost. No export value is assumed.
Complete the required assumptions to see a screening estimate.
BESS sizing + diesel displacement
Estimate battery energy, generator fuel displaced, recharge cost and operational emissions for the stated events.
Complete the required assumptions to see a screening estimate.
These screens do not include financing, tax, battery or inverter replacements, degradation over time, export revenue, or a bankable forecast. Operational savings and emissions are estimates based only on the assumptions entered. Simple payback is first-year net operating savings against installed cost, held level; it is distinct from a full cash-flow model such as SAM discounted payback (see SAM financial models). Lifecycle value is shown only when period and discount assumptions are supplied; no LCOE is calculated.
