Europe’s energy transition has reached a new turning point. Two recent regulatory reforms — Spain’s Anti-Blackout Decree and France’s TURPE 7 grid tariff framework — are redefining how battery energy storage systems (BESS) generate value. While both aim to accelerate renewable integration and system flexibility, their mechanisms also signal a clear shift: profitability in the storage sector will increasingly depend on operational precision and data intelligence.
Spain Accelerates Hybridization And System Resilience
Spain’s so-called “Anti-Blackout Decree” (Royal Decree 1183/2020) — updated through subsequent measures aligned with the country’s Energy Storage Strategy 2030 — sets an ambitious national target of 22.5 gigawatts of energy storage by 2030. The reform prioritizes hybridization between existing renewable assets and new storage facilities, allowing developers to combine solar or wind generation with batteries under simplified administrative procedures.
By streamlining environmental reviews, enabling the reuse of prior studies, and strengthening grid operator oversight, Spain is making it easier and faster to deploy large-scale energy storage. The decree’s intent is not only to enhance resilience during supply shocks but also to align grid capacity with Europe’s broader decarbonization pathway.
For independent power producers (IPPs) and investors, these changes effectively remove one of the biggest historical barriers to storage growth: permitting complexity. The result is a clearer pipeline and greater certainty in project timelines — both critical factors for capital allocation decisions in long-duration storage.
France Monetizes Flexibility Through Locational Tariffs
France’s latest grid tariff reform, known as TURPE 7, introduces a more dynamic, location-based pricing system for electricity use and injection. Instead of uniform transmission fees, storage operators now face tariffs that vary according to time and grid congestion levels.
In practice, this means that batteries can be rewarded for discharging when and where the grid needs it most — during peak demand or in constrained zones — and pay less for energy movements that relieve stress on the network. The reform transforms grid interaction from a fixed cost to a variable revenue opportunity.
This approach underscores a broader European trend toward “flexibility markets,” where timing, precision, and locational awareness are as valuable as installed capacity. It also creates a strong economic signal for developers to co-locate assets strategically rather than deploy storage purely where generation potential is highest.
The New Profitability Equation: Data As A Strategic Asset
For storage owners and operators, the implications are profound. Market value will increasingly hinge on the accuracy of data and the sophistication of analytics driving dispatch decisions. Understanding real-time State of Charge (SoC), State of Health (SoH), and curtailment impacts can now determine the difference between profit and loss.
By connecting operational data to financial performance, storage operators can optimize asset availability, reduce degradation, and precisely align dispatch with price signals from wholesale and balancing markets. Those who invest early in integrating technical and commercial analytics will gain an edge in predicting — not merely reacting to — market volatility.
Moreover, as grid operators across Europe explore similar tariff models, the experience in Spain and France is likely to become a blueprint for the continent. The emerging reality is that BESS profitability will depend less on megawatt-hours installed and more on how intelligently those megawatt-hours are managed.
The Road Ahead
The European Union’s evolving policy landscape is turning energy storage into both a technical and digital enterprise. The reforms in Spain and France demonstrate that system-level resilience and private profitability can align — but only when operators have the data systems, forecasting tools, and market foresight to act dynamically.
As Europe races toward its 2030 storage goals, the next phase of competitiveness will not be about who installs the most batteries, but who manages them with the greatest precision. For asset managers and investors, that means one imperative above all: treat data as infrastructure.
What do the new reforms in Spain and France change for BESS?
They put energy storage at the center of Europe’s energy transition. In practice, BESS profitability becomes far more dependent on operational
precision, system response, and data intelligence than simply on how many megawatt-hours are installed.
What is Spain’s “Anti-Blackout Decree” and what is its main goal?
Spain’s “Anti-Blackout Decree” (Royal Decree 1183/2020 and subsequent updates) is part of the country’s Energy Storage Strategy 2030, targeting
22.5 GW of storage by 2030. Its goal is to increase system resilience, accelerate storage deployment, and align grid capacity with Europe’s
decarbonization pathway.
How is Spain making hybridization between renewables and storage easier?
Spain has simplified permitting and administrative procedures so that existing wind and solar plants can be hybridized with batteries more quickly.
This includes reusing prior environmental studies, streamlining reviews, and giving TSOs/DSOs more tools to oversee new hybrid assets, which shortens
time-to-market and gives investors more certainty on project timelines.
What is TURPE 7 in France and how does it impact storage systems?
TURPE 7 is the latest French grid tariff framework. Instead of uniform transmission and distribution fees, tariffs now vary by location, time, and
grid congestion. For storage operators, this turns grid interaction into a dynamic lever: batteries can be rewarded for discharging when and where the
grid is under stress and pay less when their operation helps relieve congestion.
How do Spain and France differ in their approach to BESS?
Spain focuses on removing development and permitting barriers and boosting total storage capacity. France focuses on monetizing system flexibility with
locational and time-based tariffs. Together, they show a clear trend: more storage capacity in the system and revenues aligned with the real flexibility
value delivered to the grid.

For operators, the opportunity lies in combining both trends: develop storage where it is easiest to build and operate it where it creates the most
value for the grid.
Why are SoC, SoH, and curtailment data critical for storage profitability?
Because revenue now depends on how and when the battery operates. Without real-time visibility into State of Charge (SoC), State of
Health (SoH), and curtailment impacts, operators risk dispatching at the wrong time, accelerating degradation, and missing price signals in wholesale
and balancing markets that could turn flexibility into revenue.
Who benefits the most from these reforms: IPPs, utilities, or financial investors?
IPPs, utilities, and financial investors all benefit, as long as they can connect engineering, markets, and data in a single decision flow. Hybrid
portfolios and multi-country platforms are especially well positioned, because they can locate assets strategically and align dispatch to local price
and grid signals across different markets.
How do these changes affect the daily work of O&M teams?
O&M teams must go beyond traditional monitoring and:
- Integrate technical and commercial data to decide when to charge or discharge;
- Continuously track SoC, degradation, and thermal limits;
- Quantify lost revenue from curtailment or dispatch errors;
- Use forecasts to anticipate price spikes and grid constraints, instead of reacting only to alarms.
How does Delfos help connect technical and financial data in hybrid portfolios?
Delfos links operational signals to financial impact in near real time. Through smart monitoring, predictive analytics, and standardized reporting,
the platform enables teams to:
- Track availability, degradation, and curtailment KPIs across wind, solar, and storage assets;
- Optimize charge and discharge cycles based on data rather than trial and error;
- Translate technical deviations into lost or recovered MWh and revenue, supporting both operational and investment decisions.
How can operators prepare for similar reforms in other European countries?
The key is to treat data as core infrastructure. That means building:
- A reliable layer of operational and market data for all assets;
- Models that link grid signals, price curves, and curtailment to BESS dispatch strategies;
- Evidence-based O&M routines that use KPIs and forecasts, not just raw alarms.
With this foundation in place, operators will be ready to capture additional value as new storage targets and locational tariff models appear across
Europe.
