Electricity flexibility, conflict-free.
We advise industrial groups, logistics operators and multi-site energy-intensive companies on demand response, storage and flexibility monetization. A technical, independent view — free from vendor interests.
Identified demand response potential
Our deliverable is the best decision for your site — evidence-based, quantified, defensible.
manifesto
The flexibility market is mature. Advisory around it, not yet.
Most industrials receive proposals from installers, aggregators or battery vendors — each with their own bias. We start from your site, not from a solution to sell.
Three quotes, three logics, no neutral arbitration.
BESS vendors, aggregators and integrators each pitch their solution — never the objective comparison. You lose 6 to 12 months arbitrating without in-house expertise.
A theoretical ROI, never replay-tested on your data.
Opaque aggregation contracts, excessive duration.
5-10 year commitments with complex pricing grids, asymmetric penalties, unreadable revenue-sharing clauses. You sign without a comparison baseline.
No portfolio view across your sites.
Each site is optimized in isolation. Cross-site flexibility, capacity pooling and seasonal arbitrage remain blind spots — often the largest untapped resource.
Advisory aligned with your P&L, not with a vendor's.
Three principles structure each of our engagements. They guarantee that the final recommendation will hold up — before your Exco as before your CFO.
Structural independence
No commission, no kickback, no cross-shareholding with suppliers. Our compensation is 100 % fees invoiced to the end client.
- Public independence charter
- Interest declaration per engagement
- No commercial vendor partnership
Defensible deliverables
Every recommendation is quantified, sourced, version-controlled. You can present it to your Exco, compare it to received offers and, if needed, defend it in audit.
- Open Excel business case
- Technical specifications
- Offer evaluation matrix
Seven engagement formats, tailored to each step of your flex journey.
From initial audit to contracting, each service is scoped in a clear fixed-fee package — duration, deliverables. Six for industrials, one dedicated to developers seeking an expert subcontractor.
Initial audit
Complete mapping of a site's or portfolio's flexibility potential. Identification of mobilizable assets, MWh potential assessment and pre-costing of revenues by mechanism.
Scope an engagement →Demand Response Business Case
Price scenario sensitivity. Mechanisms: NEBEF, R2, AOLT, EDR, Capacity. Comparison with or without aggregator, with or without complementary BESS.
Scope an engagement →BESS Storage Owner's Engineer
Optimal sizing (power / energy / C-rate), technical specifications, tender, bid evaluation, integrator selection. You remain the project owner, we guarantee technical neutrality.
Scope an engagement →Demand Response Strategy
Arbitrage across market mechanisms (French, Spanish, EU balancing markets, capacity markets), spot market and capacity auctions. Portfolio recommendation per site with optimal allocation and participation calendar.
Scope an engagement →Flexibility Monetization
Go-to-market for flex assets: aggregator selection, aggregation tender, contract negotiation (duration, pricing, revenue sharing, penalties), legal review. Goal: maximize revenue share in your favor.
Scope an engagement →Renewables & BESS Developer Partnership
Are you a renewables developer, a BESS integrator or an ESCO pitching industrial clients? We work in white-label or co-signature mode on flex assessment, client business case and technical credibility of your proposal.
Discuss a partnership →Asset Value Optimization
Ongoing support to maximize the value of your flexible assets — from market strategy to day-to-day operational steering.
- Strategy definition for energy, capacity and flexibility markets
- Market exposure and risk management
- Investment appraisal (CAPEX, DCF, profitability)
- Market access definition and implementation
- PPA contracts and structuring
- Asset behavior modeling
- Operations optimization
- Gross margin reporting definition and monitoring
- O&M advisory services
Four steps, one principle: every decision backed by data.
We apply the same methodology across every engagement, from a fast audit to a full BESS owner's engineer role. Deliverables are versioned, open, transferable to your internal teams.
Resource mapping
Collection of 15-min load curves, process interviews, review of supply and existing flex contracts. Identification of mobilizable assets and MWh potential estimate.
Business case, scenario analysis
Market analysis, spot prices, mechanisms, local market, process constraint cost. Revenue breakdown by mechanism, IRR/NPV, sensitivity analysis.
Defensible recommendation
Strategic memo + open Excel model + three quantified scenarios. Exco presentation, objection review, final arbitration with senior management.
Execution plan (specs, tender, etc.)
Technical specs, tender launch, objective evaluation, contract negotiation, legal review. You sign the contract you designed.
Three engagements, three sectors, one principle: numbers decide.
Cases anonymized at our clients' request. Numbers are real; detailed methodology available on request under NDA.

Resilient was founded in response to a simple observation: on the flexibility market, almost no player sells nothing but advisory. Most experts have one foot in a solution — batteries, EMS, aggregation, renewables.
Our team combines experience across France, Spain and Latin America, in large groups, start-ups, energy producers, aggregation and energy consulting. We decline any supplier compensation and publish our independence declaration every year.
Questions our clients ask before engaging us.
Can't find your answer? Write to us — we reply within 3 business days.
How do you concretely guarantee your independence?
Three structural mechanisms: (1) 100 % of our revenue comes from fees invoiced to the end client, with no supplier commission or kickback; (2) we publish an audited independence declaration every year; (3) each engagement includes a named interest declaration from the engagement team. Our legal statutes forbid any equity stake in a solution provider.
How long does a Flex 360° Audit take?
4 to 6 weeks for a single site, 6 to 10 weeks for a portfolio of up to 10 sites. Duration depends mainly on the availability of your 15-min load curves and the maturity of your supply contracts. We commit to a precise duration in the commercial proposal.
What is your geographic coverage?
We operate in France, Spain, Peru and Bolivia. Engagements in French, English and Spanish. Flexibility mechanisms and the regulatory framework for electricity sales vary significantly by country — RTE in France (NEBEF, R2, AOLT, EDR), REE and OMIE in Spain (aFRR, mFRR, SRAD, Servicio de Interrumpibilidad, day-ahead market), OSINERGMIN/COES in Peru, AE/CNDC in Bolivia — our methodology adapts to the local regime. See our Regulations page for a comparative view of PV and BESS by country.
How does a first conversation work?
A scoping conversation to understand your context, your assets, your decision horizon. Within 3 business days, we send you a scoped proposal (perimeter, deliverables, timeline, fixed fee). No commitment.
Let's talk about your site, your portfolio or your project.
