How Infrastructure as Code Enabled a Smarter Energy Network

Being part of the modern energy market comes with huge challenges. It is not about managing a few centralised energy sources and providing power in one direction anymore, the network is decentralised in millions of Distributed Energy Resources, renewables, rooftop solar panels, home batteries and electric vehicles. Energy flows in two ways: scalable cloud computing is often required to ingest and process the amount of telemetry data provided by IoT devices, smart meters, sensors and automated substations to assist in predictive maintenance, forecasting and end user applications that showcase daily energy consumption and costs. The hyper-volatility of the energy market demands constant updates on energy trading platforms and a digitized grid requires cyber security, compliance with regulatory frameworks and disaster recovery capabilities.

Manual intervention alone is no longer sufficient. Delays in provisioning can lead to operational and financial impacts, dissatisfied customers and even outages. Underlying technology has become critical to grid reliability and performance. It is increasingly difficult to meet modern standards without automation.

Laying the groundwork for a modern energy platform

Terraform and Infrastructure as Code (IaC) solve these issues by providing a framework that automates the provisioning of infrastructure through reusable templatesfollowing enterprise policies, best practices and reference architectures. This provides a solution featuring:

• Speed: infrastructure provisioning can be reduced from days or weeks to minutes as there is no need to deploy resources by hand, the same applies to their decommissioning.
• Reliability: recovery can be accelerated through automated redeployment.
• Auditability: supports auditability and contributes to compliance requirements.
• Security: policies are embedded in code, so it reduces the risk of misconfiguration through policy-driven deployment.
• Error mitigation: as templates follow the standard testing procedures before release, no infrastructure settings are configured by hand and chances of human error are greatly reduced.

From cloud to code: bringing the platform to life

Following the diagram, the flow is comprised of:

1. Source Control and Continuous Integration: The Terraform code for the resource modules, variables and configurations (IaC) is committed to the Azure DevOps repository. Versioning is handled by the platform using Git Tag commits pushed by the developers, these ensure what is promoted to production.
2. Orchestration and State (Terraform Cloud): TFC is in control of the different workspaces for the development, staging and production environments. It also stores the state file, tracking the current and desired state of infrastructure in Azure and helping prevent conflicting changes through state management and locking.
3. CI/CD Flow: a plan is triggered in TFC on every commit, checking syntax errors and previewing changes on Azure (CI). In CD, an approved plan (manually or via tags) is then applied.
4. Deployment (Azure): using the Azure Resource Manager API, Terraform communicates with the Azure cloud to provision the physical infrastructure being managed.

It is important to mention as well that stacks are created in the Terraform Cloud to group different resources or modules that integrate an enterprise platform. This way it is possible to deploy a full solution through automated pipelines aligned with predefined company standards, policies, and configurations. These could be entire applications or data platforms that consist of compute, databases, networking, secret vaults and storage.

Turning infrastructure into competitive advantage

In summary, a shift from manual provisioning to IaC yields several benefits for an energy company:

• Accelerated operational efficiency and time to market: speed improvements, elimination of bottlenecks and rapid scalability.
• Enhanced reliability and business continuity: rapid disaster recovery and reducing the risk of financial and reputational impact through faster recovery.
• Proactive risk mitigation and security: built-in cybersecurity and reduction of human error.
• Streamlined compliance and governance: automated auditability and enforced standardization.
