Terna Business Model Canvas

Alignment with DSOs coordinates transmission–distribution interfaces and outage planning to minimize disruption across Terna’s ~74,000 km national grid. Data sharing enables enhanced voltage control, congestion relief and smoother distributed resource integration. Joint TSO–DSO projects accelerate grid flexibility and smart grid deployment. These partnerships measurably boost end-to-end reliability and operational efficiency.

Key partnerships with regulators, ENTSO-E, DSOs, generators, OEMs and EPCs secure tariff frameworks, cross‑border coordination, grid access and supply of critical equipment, enabling Terna’s 2024 expansion and reliability targets.

Risk-based maintenance at Terna prioritizes interventions to enhance grid availability and safety, reducing unplanned outages by up to 50% through targeted actions. Condition monitoring, drones and advanced diagnostics enable predictive interventions, cutting maintenance costs by 20–30% and optimizing crew deployment. Strategic refurbishment programs extend asset life by an estimated 15–25%, lowering total cost of ownership, while standardized processes ensure regulatory compliance and consistent quality.

Long-term planning drives €1.5–2.0bn pa regulated investments (2024) across Terna’s ~74,000 km grid. 24/7 control centers and ~5 GW reserves (2024) manage renewables variability and frequency. Risk-based maintenance, digitalisation (€1bn invested 2024) and interconnector ops support reliability and EU market coupling (~95% coverage).

Engineers, operators, planners and cyber experts drive Terna’s performance, supported by a workforce of over 6,000 professionals in 2024 and annual investments into grid modernization exceeding €2bn. Codified procedures and decades of operational experience underpin >99.99% transmission availability and regulatory compliance. Dedicated regulatory and stakeholder teams secure approvals and tariff frameworks, while a strong safety culture reduces incidents and enhances system resilience.

Terna's key resources: a ~74,000 km high‑voltage grid and substations forming a >€20bn regulated asset base (2024), with >5 GW cross‑border capacity. Skilled workforce >6,000 and control rooms/SCADA/PMUs ensure >99.99% availability; annual grid modernization spend >€2bn and a €23.6bn 2024–28 capex plan, backed by investment‑grade ratings for market financing.

Grid upgrades and faster connections drive RES growth: Terna's 2024–2028 plan allocates €15.3bn to strengthen Italy's transmission network and speed renewables integration. Advanced forecasting and flexibility services cut curtailment and balancing costs by an estimated 20–30%, while storage and dynamic line rating raise hosting capacity, accelerating decarbonization at lower system cost.

Terna operates ~74,000 km of high‑voltage lines with >99.99% availability, ensuring stable supply and frequency control within ±0.02 Hz. The €15.3bn 2024–2028 investment plan expands capacity to support ~57 GW peak demand and speed renewables integration, cutting curtailment and balancing costs ~20–30%. Non‑discriminatory access and interconnectors drive market liquidity and security toward the 15% 2030 target.

Digital self-service portals streamline applications and data access for Terna, leveraging frameworks aligned with the ENTSO-E transparency platform and standard APIs.

Users can track connection status, outages and capacity in near real-time, improving operational visibility across Terna’s ~74,000 km transmission network.

APIs enable automated data exchange for market actors, accelerating processes and enhancing transparency, supporting Terna’s digitalization targets in 2024.

Terna maintains SLA-backed account teams, multi-channel incident communications and digital self-service/APIs to support 74,000 km of grid; helpdesk, training and sandboxes reduce integration failures and speed restorations, reinforcing regulator and market trust through regular reporting and post-incident reviews.

Capacity allocation and balancing markets run on Terna's dedicated systems, with transparent rules for participation and settlement ensuring predictable dispatch and imbalances management. Cross-border platforms enable market coupling across Europe, supporting efficient cross-border flows. Users access standardized, reliable processes; in 2024 Terna operates roughly 75,000 km of high‑voltage lines underpinning these markets.

Terna uses official publications, digital portals, APIs and real-time dashboards to manage grid operations and stakeholder engagement, supporting inclusive consultations and regulatory compliance across its ~74,000 km high‑voltage network. Market platforms and cross‑border coupling enable transparent capacity allocation; open data and TYNDP 2024 inputs inform planning against ~300 TWh national demand in 2024.

Suppliers, traders and aggregators rely on Terna for capacity, balancing and granular data services as Italy’s TSO manages about 74,000 km of high‑voltage lines and transmitted roughly 300 TWh in 2023. Reliable platforms and clear market rules cut transaction risk and settlement times, while six major cross‑border interconnectors expand trading opportunities. These actors demand transparency, low friction access and real‑time visibility to optimize positions and reduce imbalance costs.

Producers need fast, firm connections — Terna operates ~74,000 km and ~25 GW backlog awaiting grid integration (2024). DSOs, traders and aggregators require real‑time data and coordination; Terna transmitted ~300 TWh (2023) and invested c.€2.2bn (2023–24). Large consumers prioritize reliability and outage coordination; ENTSO‑E covers 42 TSOs and EU 2030 interconnection target is 15%.

SCADA/EMS, data platforms and telecom networks require continuous OPEX for monitoring and latency-sensitive links across Terna’s ~74,000 km transmission grid, with recurring software licensing, hardware refresh cycles and cloud services adding material yearly costs. Cyber protections for OT/IT systems are essential to safeguard this critical infrastructure and meet 2024 regulatory expectations. Ongoing investments improve system resilience, situational visibility and outage prevention.

Major capex (2024–28 ~€12.6bn) for HV lines, underground cables and HVDC; OPEX driven by maintenance, SCADA/telecom, cyber and staff (employees ~4,600) across ~74,000 km grid; balancing, losses and compliance largely passed through tariffs and regulators (NIS2, 2024).

Auctions and market coupling generate congestion rents that Terna collects from interconnector capacity sales; these rents are regulated and reported under EU transparency rules (Regulation 2019/943 and ACER transparency requirements).

Revenues are reinvested to fund reinforcements and cross-border assets, supporting Terna’s 2024–2028 investment plan of about €21.6 billion.

Allocation of capacity and rents follows EU allocation rules and publication obligations, while physical flows reflect market conditions and system needs, causing variability in congestion income year-to-year.

Core revenue: allowed return on RAB €18.2bn (2024) generating ~€3.1bn regulated revenues; regulated WACC ~4.8% with multi‑year ARERA frameworks. Performance schemes can adjust pay by up to 5% based on availability, losses and delivery. User‑paid connection fees, congestion rents and ancillary/balancing services diversify income; ancillary/data/services contributed ~€2.3bn (2024).
