Consumption analysis
Quarter-hourly load curves, tariff periods and grid access tariffs: where the money in the bill goes.
C&I studies · Battery storage (BESS) · Solar PV
Renewable energy,
from idea to grid connection.
We help industrial and commercial clients decide, with numbers, whether solar or a battery pays off. We develop PV and BESS projects for developers and investors, and bring the same engineering to homes and villas with Bali PV.

Energy and battery studies you can actually read
Before investing in solar or a battery, you need to know how much you will save and how long it takes to pay back. We calculate it with your real data and deliver it ready for a decision.
PV + BESS sizing
Self-consumption, peak shaving, contracted capacity reduction, load shifting and backup.
Savings and returns
Hour-by-hour simulation of a full year (8,760 h) with NPV, IRR, payback and levelised cost of storage (LCOS).
Technical and commercial proposal
A clear report with scenarios, assumptions and risks, and comparison of installer and manufacturer offers.
For developers and investors
Utility-scale PV and BESS development and engineering
From land and grid connection to commissioning, focused on what drives a battery's returns: revenues, contracts and degradation.
Project development
Feasibility, site selection, grid access and connection, and permitting follow-up.
BESS revenue models
Day-ahead and intraday markets, balancing services (aFRR, mFRR) and project financial models.
Engineering and RFPs
Technical reports, preliminary designs, specifications and RFPs for equipment, substations and connection centres.
Suppliers and contracts
Technical evaluation of manufacturer bids, EPC and long-term service agreements (LTSA), degradation guarantees (SOH, RTE) and investor support.

IndustryMulti-site BESS tenders for industrial plants
ManufacturersTechnical evaluation of bids from tier-1 battery manufacturers

For homes and farms
Solar installations designed for you
We look at your consumption and propose the installation that makes sense for you, without oversizing.
Self-consumption
Rooftop solar to cut your electricity bill, with or without batteries and with surplus compensation.
Off-grid homes
Solar systems with batteries for country houses and buildings with no grid connection.
Solar pumping
Direct solar-powered pumping for irrigation and water supply on farms and rural properties.
We also help you with permitting and the subsidies available at any given time.
Bali PV
Solar-plus-battery kits for homes and villas
Luxury and resilience: your home or villa on its own energy, silent and always on, even when the grid fails.
Discover Bali PV- ResilienceBackup power during outages.
- FlexibilityMidday sun, available at night.
- Villas and holidaysNo outages for guests, remote management.
How we work
A clear process, no surprises
- 01
Listen
You tell us what you need and we review your data: consumption, land, grid connection point.
- 02
Analyse
We study the options and give you clear numbers: costs, yield and payback.
- 03
Design
We prepare the engineering and documentation needed for permitting and procurement.
- 04
Support
We follow the project through to commissioning and answer questions along the way.

Thoughts on the energy transition
Articles on energy, electricity markets, storage and other topics we find interesting.
Energy transitionSelf-consumption
Fuel crisis: what if the answer is on the roof?
The Saudi crude cut to Europe has sent diesel and petrol prices soaring. A delivery-van example shows how much oil dependence costs and what role solar, batteries and electrification can play.
Bali PVSelf-consumption
Bali runs dry: lessons from an island that depends on a ship
Eight-hour queues, odd-even rationing and closed schools. Bali's October 2026 fuel crisis shows what happens when all energy arrives on a tanker, and what a villa with solar and storage can do about it.
Electricity marketStorage
What are the main challenges of the energy transition?
Spain produces more and more renewable energy, but producing a lot is not enough. Prices that collapse at midday, wasted energy and a grid that has to adapt: the challenges of the next phase.
About Ingrenov
European expertise, based in Spain
Ingrenov was founded on European expertise in renewable energy and energy storage. Based in Spain, we work on projects across Spain, Portugal, France, Italy and Germany, and know first-hand how a solar plant or a battery is developed, contracted and commissioned in each market.
Our experience covers battery studies for industry, multi-site tenders, technical evaluation of leading manufacturers, specifications for substations and connection centres, and EPC and maintenance contracts. We use our own hour-by-hour simulation tools, so every decision is backed by numbers, not guesswork.
Utility-scale know-how with a direct, personal service: one point of contact, clear answers and the same technical standard for an industrial plant, a solar farm or a villa. Your project, from idea to grid connection.
