The energy sector has always been a critical infrastructure target. What has changed dramatically over the past decade is the nature of the attack surface. As solar farms, wind parks and hydroelectric facilities modernise their control systems and connect them to corporate IT networks, they inherit the vulnerabilities of the digital world alongside the efficiencies they sought. For Turkish energy companies — from utility-scale renewable project owners to industrial energy consumers — understanding this evolving risk landscape is no longer optional. It is a prerequisite for sustainable operations and financial resilience.

The Convergence of IT and Operational Technology

Historically, operational technology (OT) — the hardware and software that monitors and controls physical processes — was isolated from information technology (IT) networks by design. A substation's programmable logic controllers (PLCs) ran on proprietary protocols that had no connection to the internet. A wind turbine's supervisory control and data acquisition (SCADA) system communicated only with the site's local control room. That isolation was a de facto security control.

Today that air gap has largely closed. Remote monitoring reduces operational costs and enables predictive maintenance. Cloud-based analytics platforms improve asset performance. Grid operators require real-time telemetry from all connected generation assets. These are legitimate business drivers, but they create pathways between the corporate IT environment — with its email clients, web browsing, and remote-access tools — and the OT environment that directly controls physical processes.

The consequence is significant: a threat actor who gains access to an energy company's IT network now has a potential route to the OT systems that govern whether turbines spin, breakers trip, or metering data reaches the transmission operator. The techniques used to compromise IT systems — phishing, credential theft, exploitation of unpatched software — can be repurposed to reach industrial control systems that were never designed with cyber adversaries in mind.

Attack Vectors Targeting the Energy Sector

Three categories of attack dominate the energy sector threat landscape and are directly relevant to Turkish operators.

Ransomware

Ransomware groups have made critical infrastructure a priority target precisely because the pressure to restore operations is intense. An energy company facing a grid disconnection notice from the transmission operator, or a renewable asset under a YEKDEM feed-in tariff at risk of losing generation hours, faces enormous financial incentive to pay a ransom quickly. Ransomware variants specifically designed to propagate from IT to OT networks — including those that can disable safety instrumented systems — have been documented in multiple major incidents globally.

Supply Chain Compromise

Energy companies rely on a wide ecosystem of equipment vendors, software suppliers, maintenance contractors and grid operators. A compromise of any one of these upstream parties can provide an attacker with trusted access to multiple downstream targets simultaneously. Software updates pushed by a SCADA vendor, remote-access sessions opened by a maintenance contractor, or firmware downloads from an inverter manufacturer's portal all represent supply-chain vectors that are difficult for individual companies to control.

Insider Threat

Disgruntled employees with access to control systems, contractors with excessive privileges, or individuals coerced by external actors represent an insider threat that is particularly difficult to detect in IT/OT environments where activity monitoring is less mature than in pure IT settings. The damage potential is high: an insider with legitimate credentials does not need to defeat perimeter security at all.

The Turkish Energy Sector in Focus

Turkey's energy transition has created a large and growing population of digitally controlled assets. Unlicensed and licensed solar power plants (GES — güneş enerji santrali), wind farms (RES — rüzgar enerji santrali), and hydroelectric plants (HES — hidroelektrik santral) represent tens of thousands of individual installations, many of which have adopted remote monitoring and smart inverter technology.

The YEKDEM renewable energy support mechanism requires metering data to be transmitted in real time to EPDK (Enerji Piyasası Düzenleme Kurumu) and the market operator TEİAŞ. This regulatory metering infrastructure has its own cybersecurity profile, and a compromise of metering systems — whether by manipulating reported generation figures or by disrupting the transmission of settlement data — carries both operational and regulatory consequences.

Industrial energy consumers — manufacturing facilities, data centres, hospitals — face a related but distinct set of risks. Their energy management systems, building automation networks and facility SCADA installations often sit on the same flat network as corporate IT, with limited segmentation and monitoring.

The most dangerous assumption an energy company can make is that its operational technology is too specialised, too proprietary, or too isolated to be targeted. Attackers have demonstrated, repeatedly, that OT environments are reachable and that the disruption they cause commands attention.

KVKK and the 72-Hour Notification Obligation

Turkey's Personal Data Protection Law (Kişisel Verilerin Korunması Kanunu, KVKK, Law No. 6698) imposes obligations on data controllers that are relevant to energy companies, even though the primary business of an energy operator is generating or transmitting power rather than processing personal data.

Energy companies hold personal data in several contexts: employee records, customer billing data (for licensed suppliers and retail market participants), visitor logs, and the data collected by human-resources and ERP systems. A cyber incident that compromises these systems triggers KVKK's breach notification framework. Article 12 of KVKK and the Personal Data Protection Authority's (Kişisel Verileri Koruma Kurumu, KVKK) supplementary regulations require that breaches be notified to the Authority as soon as the controller becomes aware of the incident — and current guidance expects notification within 72 hours, broadly consistent with the GDPR standard applied in EU markets.

Failure to notify within the required timeframe, or to notify at all, exposes the organisation to administrative fines that can be substantial. For energy companies with operations in EU member states or with EU-based commercial counterparties, dual compliance obligations — KVKK and GDPR — may apply simultaneously.

Anatomy of a Cyber Insurance Policy for Energy Companies

Cyber insurance has evolved considerably from its origins as a data-breach product. Modern policies marketed to energy and industrial companies typically comprise two broad sections, each covering a distinct set of exposures.

First-Party Covers

First-party sections respond to losses the insured suffers directly as a result of a cyber incident:

Third-Party Covers

Third-party sections respond to claims made against the insured by others arising from the cyber incident:

Exclusions That Catch Energy Clients Off Guard

The exclusions in a cyber policy can dramatically limit its value in the very scenarios that energy companies most fear. Understanding these exclusions — and negotiating their scope at placement — is one of the most important things a broker does.

Physical damage trigger: Many cyber policies exclude business interruption losses unless the interruption is caused by a computer system failure. If a cyber attack causes physical damage to generation equipment — for example, a SCADA manipulation that causes a turbine to operate outside safe parameters and suffers a mechanical failure — recovery may fall between the cyber policy (which excludes physical damage) and the property policy (which may exclude cyber-induced losses). This gap has been the subject of significant market debate and litigation, and specialist endorsements to bridge it exist but must be specifically requested.

Cyber war and nation-state attribution: Following several market-wide disputes over the attribution of major attacks to state actors, many cyber policies now include specific exclusions for war, acts of a sovereign or quasi-sovereign body, and critical infrastructure attacks linked to geopolitical conflict. For energy companies — which are by definition critical infrastructure — understanding the scope of these exclusions is essential.

Infrastructure failure: A power outage caused by a failure in the national grid — even if that failure was itself caused by a cyber attack on the grid operator — may not trigger a cyber policy's business interruption cover if the policy requires the failure to originate within the insured's own systems.

Unpatched systems: Some policies include warranty conditions requiring the insured to maintain software at current patch levels. An energy company operating legacy SCADA systems that cannot be patched without disrupting operations — a common situation — may find coverage conditions difficult to meet without careful wording negotiation.

A Loss Scenario: SCADA Compromise to Business Interruption

Consider a Turkish wind farm operator running fifteen turbines under a YEKDEM feed-in tariff. The operator uses a cloud-connected SCADA platform provided by a European software vendor for remote monitoring and turbine health analytics. A threat actor compromises the vendor's update infrastructure and pushes a malicious firmware update to all connected customers. The update installs a backdoor in the wind farm's SCADA environment.

Three weeks later, during peak generation hours, the attacker activates the backdoor, issues commands that instruct the turbines to disconnect from the grid, and deploys ransomware across the corporate IT environment simultaneously. The generation control system cannot be accessed remotely — the corporate VPN is down — and the on-site technician is unable to override the system commands without vendor support.

The turbines remain offline for sixty-two hours while the vendor deploys a remediation team. During that period, the farm generates no electricity and receives no YEKDEM payments. The forensic investigation adds further cost. The KVKK Authority must be notified within 72 hours because the corporate IT compromise also affected the HR system. A neighbouring landowner claims that a turbine that was improperly shut down swung its nacelle and damaged a boundary fence.

This scenario involves first-party business interruption, forensic costs, regulatory notification obligations, and a third-party liability claim — all from a single incident that entered through a trusted vendor's update channel.

Quantifying Your Cyber Exposure Before You Buy

Cyber insurance underwriters increasingly require applicants to complete detailed technical questionnaires covering the maturity of their information security controls. For energy companies, additional questions will typically address OT-specific controls: network segmentation between IT and OT, the existence of a demilitarised zone (DMZ) between environments, patch management practices for industrial control systems, and the availability of manual override capabilities.

Beyond the underwriting questionnaire, companies considering cyber insurance would benefit from a pre-placement exposure assessment covering:

How a Broker Supports Energy Sector Clients

Placing cyber insurance for an energy company is not the same as placing a standard commercial cyber policy. The underwriting process is more detailed, the policy wording questions are more technical, and the potential interaction with property and engineering covers requires careful coordination across all lines of coverage.

An independent broker brings several distinct capabilities to this process. At placement, the broker can access a broad panel of underwriters — including specialist London market capacity that has developed genuine expertise in energy-sector cyber risk — and present your risk in a structured way that reflects your specific OT environment, control framework, and sector exposures. This competitive access typically produces better terms than a direct approach to a single insurer.

During the policy period, the broker serves as a resource when questions arise about coverage applicability — for example, when a vendor announces a vulnerability in widely used SCADA software and management wants to know whether an incident arising from that vulnerability would be covered. And when an incident occurs, the broker's incident response coordination capabilities — including access to pre-agreed forensic and response panels — can materially shorten the time from discovery to containment.
