Cybersecurity FAQs for Renewable and Storage Operators

Forty frequently asked questions and answers in five categories, written for leadership, CISOs, asset management, O&M, procurement and metering teams.

In this document 1.  Category 1: Cyber risk, governance and strategy 2.  Category 2: CEA Regulations and compliance 3.  Category 3: Equipment, sites and storage 4.  Category 4: Clouds, connectivity and monitoring 5.  Category 5: Smart metering, privacy and growth

Audience: Boards, CEOs and CISOs

Q1. Why are renewable fleets a cyber target?

They are remotely operated through vendor clouds and connected devices across many sites, so a single compromise can affect a whole fleet.

Q2. What are the biggest risks?

Vendor cloud abuse, insecure or undocumented equipment, exposed controllers, connectivity loss, storage system compromise and smart meter attacks.

Q3. Which incidents illustrate the risk?

A 2022 satellite attack cut remote monitoring of about 5,800 German wind turbines, and in 2025 US officials reported undocumented devices in some imported inverters.

Q4. Who must lead cybersecurity?

For covered entities, a senior CISO with an alternate under the CEA Regulations (as reported).

Q5. What should the Board review?

CEA readiness, vendor access, equipment inspection results, incidents, monitoring coverage and drills.

Q6. Do lenders care about cybersecurity?

Increasingly yes; independent assurance supports financing and insurance.

Q7. How should we prioritise investment?

Lock down vendor and cloud access, remove exposed controllers, inspect equipment and then build fleet monitoring.

Q8. How can Codec Networks help?

Codec Networks provides OT/IoT assessments, vendor cloud reviews, equipment inspection, fleet monitoring and CEA compliance support.

Audience: Compliance and CISO offices

Q9. Do the CEA Regulations apply to renewables?

As reported, they cover generating companies, captive plants and storage operators of 50 MW and above.

Q10. When do they apply?

The regulations were notified on 31 July 2026 and come into force on 1 April 2027.

Q11. What about smaller plants?

As reported, smaller entities are encouraged to adopt CERT-In's basic cyber security controls for MSMEs.

Q12. What governance is required?

A senior CISO and alternate, a 24-hour Information Security Division, a policy and a crisis management plan with annual drills (as reported).

Q13. Are audits required?

As reported, critical systems must be audited annually.

Q14. How fast must incidents be reported?

As reported, to CSIRT-Power and CERT-In within six hours.

Q15. How do we confirm the 50 MW threshold for our assets?

Check the definitions in the official gazette notification and take advice on portfolio and hybrid configurations.

Q16. Can Codec Networks audit us?

Yes. Codec Networks is CERT-In empanelled and performs gap assessments and IT/OT audits.

Audience: Asset, O&M, engineering and procurement teams

Q17. Should we inspect new inverters?

Yes. Inspect hardware and firmware for undocumented communications and insecure defaults before deployment.

Q18. How should site networks be designed?

Segment control, vendor and IT traffic, allow-list communications and avoid internet exposure.

Q19. How do we handle default credentials?

Change them at commissioning, use unique credentials and verify during audits.

Q20. How should battery systems be secured?

Test EMS and BMS, restrict access, monitor changes and keep safety interlocks independent of networked control.

Q21. What about unmanned sites?

Combine physical security, tamper detection and monitoring of device changes.

Q22. How should firmware updates be handled?

Accept only signed updates from verified sources, test before rollout and keep rollback options.

Q23. How should O&M contractors get access?

Through named, time-bound, monitored access with MFA, removed when work ends.

Q24. What should procurement require?

Security requirements, SBOMs, update commitments and inspection rights in equipment contracts.

Audience: Asset management, IT and SOC teams

Q25. How should OEM portals be secured?

Named accounts, MFA, role-based permissions, approvals for fleet-wide commands and monitoring.

Q26. What if the OEM cloud is compromised?

Plan local fail-safe operation, monitor for unusual commands and agree incident terms with OEMs.

Q27. How do we make connectivity resilient?

Use diverse links, assess providers and ensure sites operate safely without telemetry.

Q28. What should fleet monitoring cover?

Device and controller changes, portal commands, remote sessions, output anomalies and threat intelligence.

Q29. How long must logs be retained?

CERT-In requires ICT logs for a rolling 180 days within India.

Q30. What should incident playbooks include?

Safe operation, containment, OEM coordination, grid coordination and CSIRT-Power and CERT-In reporting.

Q31. Should we run drills?

Yes. The CEA Regulations require at least one mock drill a year for covered entities (as reported).

Q32. How should asset management platforms be protected?

Test applications, protect privileged access and keep immutable backups.

Audience: AMISPs, DISCOM partners and privacy teams

Q33. Why are smart meter head-ends critical?

They can read, configure and disconnect large numbers of meters.

Q34. How should head-ends be secured?

Strong admin controls, approvals and rate limits for bulk commands, testing and monitoring.

Q35. How should meter firmware be updated?

Signed updates, verified on the meter, staged with rollback and monitored.

Q36. Does DPDP apply to metering data?

Yes, where it relates to identifiable consumers; most DPDP obligations take effect in May 2027.

Q37. What do DISCOMs expect from AMISPs?

Security controls, reporting and evidence defined in contracts.

Q38. How should acquisitions be handled?

Review acquired portfolios' OT security, vendor access and compliance before integration.

Q39. What about EV charging networks?

Charging platforms add connected devices and payment flows that need testing and monitoring.

Q40. How can we start with Codec Networks?

Begin with a scoping call on your portfolio, OEMs and timelines; Codec Networks will propose an assessment plan.
