HED is how Charania Renewables approaches every commercial and industrial energy project. Not a product. Not a service package. A methodology: start with your data, model the economics, design the system, then specify the technology. Every project we touch is run through this sequence — because the most expensive mistake in energy is building the wrong system for the right problem.
Load profiles, utility bills and site surveys collected before any technology is considered.
LCOE, payback period, NPV and IRR modelled at conservative assumptions before specifying a product.
We specify the best technology for your site economics — not the product with the highest margin.
SLDs and specifications handed to EPC and installation partners. CR manages design authority and coordination.
Pakistan’s energy market is full of companies that sell products first and design second — or not at all. A solar installer recommends a system based on available roof space, not your actual load. A battery distributor recommends a capacity based on what they have in stock. An EPC tenders based on the spec they know, not the one your site requires. The result is systems that underperform, economics that don’t materialise, and clients who don’t realise they’ve been sold the wrong thing until year two.
HED exists because we believe the design and financial case should come before the product. Not every site needs a hybrid system. Not every site that needs one should have the same configuration. The analysis tells you what is right. We do the analysis.
12-month load profile analysis, peak demand identification, grid tariff breakdown and site solar and wind resource assessment. The factual foundation everything else is built on.
LCOE calculation, payback period, NPV and IRR at conservative, base and optimistic assumptions. Sensitivity analysis on grid tariff escalation and technology degradation. The business case in numbers, not narrative.
Generation mix (solar kWp, wind kW), storage sizing (kWh and power rating), inverter and PCS selection, grid connection strategy, EMS dispatch logic and controls architecture.
Single-line diagrams, protection coordination, grid connection drawings and equipment specifications. Issued for authority approval, EPC tendering and contractor use.
Tender document preparation, EPC partner evaluation, construction supervision, commissioning oversight and final handover documentation. CR as design authority throughout.
Post-commissioning generation and financial performance review against the original model. Identifying underperformance early and correcting it before it compounds.
A solar-only system generates nothing after sunset and little on overcast days. A wind-only system is idle in calm periods. A storage-only system drains without generation behind it. The HED approach combines all available generation sources and storage into a single managed architecture — each source compensating for the limitations of the others. Solar peaks at midday. Wind generates in the evening, at night and in overcast conditions. Storage smooths the supply curve, absorbs excess generation and discharges during peaks or grid outages. The EMS coordinates all three in real time against your tariff structure and availability requirements.
The result is a higher proportion of on-site generation, a flatter cost of energy curve and a more bankable investment case than any single-source system can deliver.
Every HED engagement follows the same four-phase sequence. The phases are sequential because each one informs the next. Skipping phases is how bad systems get built.
