Frequently Asked Questions

Answers to common questions about our EPC model and scope.

What is included in Keypower’s turnkey solar EPC scope?+
Project consulting, site surveys, feasibility studies, engineering, equipment procurement, construction, testing, commissioning, performance management, and, when needed, plant modernization and repowering are managed within a single project delivery structure.
How is capacity determined for a solar-plus-storage plant?+
Battery power and energy capacity are determined by evaluating the generation profile, load profile, interconnection conditions, operating strategy, and investment objectives together.
Do you provide feasibility and investment return analyses?+
We prepare an investment-grade report by evaluating energy yield forecasts, technical losses, capital and operating expenses (CAPEX/OPEX), payback period, depreciation, and multiple capacity scenarios.
Can battery storage be added to an existing solar power plant?+
Yes. We assess the plant’s electrical infrastructure, interconnection capacity, generation profile, and control systems, then engineer the appropriate BESS, PCS, and EMS architecture.
Do you provide performance management after commissioning?+
Yes. We use SCADA data to monitor generation, availability, performance ratio, losses, and alarms, then provide root-cause analysis and improvement recommendations when deviations occur.
When are plant modernization and repowering needed?+
Plant modernization and repowering are evaluated when equipment is aging, performance is declining, failure rates are rising, grid requirements have changed, or storage integration is required.
What information do you need to start an EPC project?+
For an initial assessment, we need site or facility information, consumption and generation data, interconnection documentation, the target capacity, and any existing project documents.
