Aurora's Grid
Swiss software suite that makes lithium-ion battery storage profitable by treating ageing as a design constraint. It sizes batteries, runs an ageing-aware energy management system, and supervises deployed fleets from a single console.
What is Aurora's Grid?
Aurora's Grid is a Swiss software publisher, founded in October 2016 at the EPFL Innovation Park by Dr Dimitri Torregrossa, whose positioning is summed up in one line: enabling ageing-aware integration of battery storage. Its premise is that most battery projects are judged on price and capacity while the thing that actually decides their economics, how fast the cells degrade, is left out of the calculation. The company sells three complementary pieces of software built around that idea.
EMMA, described as the main product, is the energy management software. It couples electrochemical knowledge of lithium-ion cells with grid constraints, machine learning and forecast algorithms, and can run on anything from a household installation up to utility scale. It covers six combinable applications: renewable self-consumption, load peak shaving, feed-in peak shaving, primary control reserve, secondary control reserve, and mixtures of these. The publisher claims up to 35% more renewable self-consumption, more than 40% less ageing, up to 30% longer service life and over 20% less battery carbon footprint, with the EMS described as hardware-agnostic, plug and play, and commissioned in under sixty minutes.
Fleet Management is the supervision layer. It gives secure remote access to every EMS deployment, with real-time energy flows and history, remote on/off switching and mode changes, email and SMS alerts, shareable read-only access for end users, and a view of the financial benefit each site is producing.
Aurora's Grid 4.0 is the battery-sizing emulating platform, and a public version of it is open on the site. It emulates system behaviour over the battery's lifetime, lets the user pick a chemistry, models C-rate, mid-state-of-charge, temperature and depth-of-discharge effects, computes state of health, and works out the optimal battery and inverter size along with the revenue each service would bring.
Applications span residential and industrial buildings, commercial and industrial sites, utility-scale plants, EV charging, vehicle-to-grid and second-life batteries. The company reports deployments across three continents and more than nine European countries.
What it does
- Size a battery and its converter, sweeping kWh and kW ranges to find the optimal pair
- Emulate performance across the whole battery lifetime and compute state of health and ageing
- Estimate profitability, revenue stream by revenue stream, with a discount rate
- Manage charge and discharge to maximise renewable self-consumption
- Shave both consumption peaks and renewable feed-in peaks
- Bid the battery into primary and secondary frequency reserve markets
- Supervise a fleet of installations remotely, with alerts and on/off control
When to use Aurora's Grid / When not to
A quick filter to help you decide if Aurora's Grid is the right fit.
When to use Aurora's Grid
- Battery storage operators weighing investment cost against the revenue a system can actually earn
- System integrators and OEMs looking for a hardware-agnostic EMS that commissions in under an hour
- Utilities and aggregators bidding batteries into primary and secondary frequency reserve markets
- Facility and building owners combining rooftop solar, peak shaving and EV charging on one site
- Engineering consultancies sizing a PV-plus-battery pair before committing to a capital decision
When not to use Aurora's Grid
- Buyers who need a published price list, since nothing is quoted publicly and every deal goes through sales
- Procurement teams that require written GDPR commitments or a DPA up front, as the site publishes no legal pages at all
- Anyone wanting a self-service signup, because the contact form is switched off and only named staff addresses exist
- Teams working outside English or French, the only two languages the product interface offers
- Users expecting a mobile app or a chemistry outside the lithium-ion families the models cover
How to use Aurora's Grid
A typical end-to-end flow, from setup to results.
- Open the public battery-sizing tool at the demo page; no account or registration is required
- Set the general parameters: start date, simulation window in days and simulation timestep in seconds
- Enter the financial parameters: peak and off-peak retail tariffs, feed-in tariff, power cost, discount rate and currency
- Upload or describe the renewable production profile and the load consumption profile, or scale an existing plant
- Select the battery services to evaluate: self-consumption, load peak shaving, feed-in peak shaving, PCR and SCR
- Choose the strategy, comparing the Aurora's Grid EMS against a standard EMS
- Set the battery parameters: chemistry, ageing effects, size range, converters, price, nominal cycles and efficiency
- Run the simulation, then save the chart, save the table or generate a detailed report
- For the EMS itself, contact the company to request a demo version, since the on-site form is out of service
- Once deployed, sign in to the fleet application to monitor sites, control systems and manage alerts
Pros & Cons
Pros
- Ageing modelling at a level of detail rarely exposed in this market, across several lithium-ion chemistries
- Three complementary tools covering the whole cycle, from pre-sales sizing to operation and fleet supervision
- The sizing platform can be tried publicly, with no account and no sales contact
- EMS presented as hardware-agnostic and commissioned in under an hour, with one architecture for all segments
- Genuine scientific grounding, with EPFL and Empa collaborations and an award-winning conference paper
- Named customers and partners including Services Industriels de Lausanne, Romande Energie, Leclanche and Groupe PSA
- External recognition: two Solar Impulse Efficient Solution labels, a PERL 2019 jury prize and a Swiss federal energy grant
Cons
- No legal documentation whatsoever: no terms, no privacy policy, no legal notice and no DPA
- No public pricing and no commercially documented free trial; every route runs through a sales conversation
- The contact form is out of service and only named staff addresses exist, with no generic support mailbox
- The showcase site is frozen, with the latest news dated June 2024 and the demo tool still marked 2021
- The address shown on the site is outdated: the commercial register moved the seat to Renens in January 2026
- Performance figures are asserted without a published study or accessible methodology
- Product interface limited to English and French, with no mobile application
Pricing & Plans
No pricing is published. The pricing page does not exist, no sitemap or llms.txt is served, and no monetary amount appears on any product page. The commercial model observed is contract-based industrial licensing: the company announced delivering two additional industrial licences of EMMA 1.0 to Romande Energie SA in July 2020, and the products page invites visitors to request a demo version by contacting the company, with a customised version available on request. No permanent free plan is advertised and no free trial is offered commercially. Readers should note that the amounts visible inside the battery-sizing tool, retail and feed-in tariffs, power cost, battery price and reserve prices, are simulation inputs entered by the user, and the eight selectable currencies belong to that simulation. None of them represents the price of the product.
Data, GDPR & hosting
A consolidated view of how Aurora's Grid handles your data.
GDPR overview
There is no mention of the GDPR anywhere, and that absence should be stated plainly. Aurora's Grid publishes no privacy policy, no cookie notice, no legal notice and no terms; the four usual paths return the site's 404 page, and no occurrence of GDPR, data protection or cookies exists in any collected page or its underlying HTML. No Article 27 representative is named, no data protection contact is offered, and no processing purpose, legal basis or retention period is described. The publisher is Swiss, so it falls primarily under the revised Federal Act on Data Protection rather than the GDPR, but it claims deployments in more than nine European countries, which would bring European personal data within scope. Buyers should treat GDPR terms as something to obtain contractually, since the site documents none.
Who owns the data?
Nothing can be established here. Aurora's Grid publishes no terms and conditions, no privacy policy and no legal notice: the /terms, /privacy, /legal and /imprint paths all return the site's standard 404 page, and the words 'privacy', 'GDPR' and 'data protection' appear nowhere in the collected material. No clause therefore states who owns measurement data, telemetry or simulation inputs, nor what the vendor may do with them. The only ownership signal is functional: the fleet application runs on per-account authentication with owner and client roles, and lets a customer share a secure read-only view with end users, which implies the customer administers access. Ownership itself remains contractually undefined and should be settled in writing before any deployment.
Reuse rights
No contractual document governs reuse, because the vendor publishes none. There is consequently no licence granted to the customer over exported material, and equally no restriction stated against it. In practice the sizing tool lets anyone upload their own production, consumption, frequency and SCR demand profiles and take the results away: charts and tables can be saved and a detailed report generated, with no registration and no stated conditions attached. The fleet application likewise exposes energy-flow history, charger usage history and EMS modification logs to the account holder. What a customer may then do with any of it is simply not addressed anywhere on the site, and should be negotiated directly with the vendor.
Data retention & training
Hosting summary
The publisher declares nothing about hosting. There is no privacy policy, no security page and no trust page, so no jurisdiction, region, data centre or subprocessor is stated anywhere, and no list of third parties processing customer data is published. What can be observed is purely technical and should not be read as a commitment by the vendor. The showcase site resolves to an Infomaniak server in Geneva, Switzerland. The Fleet Management application, which is where customer system data would actually live, resolves to a Hetzner Online address in Nuremberg, Germany. The two therefore sit in different jurisdictions, one inside the European Union and one outside it, which matters for anyone assessing transfer questions. Because none of this is contractual, a buyer with hosting or residency requirements should obtain them in writing rather than infer them from where the servers happen to answer today.
Things to keep in mind
Risks and trade-offs to weigh before adopting Aurora's Grid.
- No contract governs your data: with no terms or privacy policy published, ownership of telemetry, site profiles and simulation inputs is undefined and settled only by whatever you negotiate directly
- Sizing outputs are a model, not a promise; the headline gains of 35% self-consumption or 40% less ageing depend on site conditions the vendor explicitly qualifies, and treating them as guaranteed can distort an investment case
- Uploading production and consumption profiles means handing over a detailed picture of a building or plant's operations, to a service whose retention period is nowhere stated
- Remote on/off and mode control over physical battery assets is powerful and consequential; account sharing, weak passwords or stale access rights carry real operational risk
- Leaning on an automated ageing model can erode the in-house engineering judgement needed to challenge it, especially where the methodology is not published and cannot be audited
- The site's published address and news are outdated by a year or more, so any detail taken from it, including contact routes, should be reconfirmed before relying on it
- A module labelled Free Trial Edition exists in the application but is not a commercial offer; do not plan a budget around a trial the company does not advertise
Setup & Integrations
Technical difficulty
Two very different levels. The public sizing tool needs no account, but it does expect expert inputs: production and consumption profiles uploaded as files, frequency profiles, SCR demand signals, ageing parameters and reserve prices. Without that data it cannot be used meaningfully. The EMS is a different matter: the vendor claims plug-and-play commissioning in under sixty minutes and a hardware-agnostic design, but it remains an on-site installation wired to the battery, the BMS, the inverters and the grid meter. Day-to-day fleet supervision afterwards is straightforward browser work. No public installation documentation exists.

Should you pick Aurora's Grid?
Aurora's Grid is a narrow, deeply specialised tool, and that is its strength. Very few vendors expose battery ageing at this level of detail, with C-rate, mid-state-of-charge, temperature and depth-of-discharge effects modelled across several chemistries and fed straight into both the sizing decision and the operating strategy. The technical maturity is real and checkable: software versions have run from 1.0 through to 4.3, the sizing platform is open to anyone without an account, the fleet application is live with a documented API, and the customer and partner names attached to it, Services Industriels de Lausanne, Romande Energie, Leclanche, Groupe PSA, Empa, are verifiable Swiss and European institutions. Two Solar Impulse labels, a PERL jury prize and a Swiss federal energy grant of 367,680 CHF point the same way.
The commercial and documentary side is well behind. There is no published price, no free trial that the company actually stands behind, a contact form the site itself says is out of service, and, most significantly for any professional buyer, no legal documentation at all: no terms, no privacy policy, no legal notice, no mention of the GDPR. The showcase site has not moved since June 2024 and still shows an address the commercial register superseded in January 2026.
That gap should be read for what it is. The company itself is demonstrably active, with a register filing in January 2026 and recent public activity, so this is a small engineering-led team that has invested in its product and not in its web presence. For a buyer who can conduct due diligence directly, the substance is there; for one who needs written commitments before the first conversation, the site supplies none.
