API Management for Energy Sector

Improving API Governance and Developer Experience Using Azure

Overview

A large utility provider runs many customer and internal systems using APIs. As their digital services expanded, managing security and access became difficult. They approached Krish Services to implement Azure API Management, creating a central platform that improved security controls, simplified integrations, and gave teams better visibility and control across all APIs.

Client Background

The client is a utility provider delivering power and energy services across multiple regions. Their operations depend on customer portals, internal applications, and partner systems that exchange data through hundreds of APIs. These systems support daily service delivery, billing, monitoring, and customer interactions across a wide digital ecosystem.

Challenges

  • Uncontrolled API Expansion: Different teams built and published APIs separately, with no central visibility, shared standards, or consistent monitoring across environments.
  • Security and Compliance Gaps: APIs used mixed authentication methods, weak access controls, and undocumented endpoints, increasing security exposure and audit risks.
  • Limited API Visibility and Governance: Operations teams lacked a single view to track API usage, performance, versioning, and ownership across internal and external systems.
  • Slow Partner and Developer Onboarding: Partners had no central portal or clear documentation, causing confusion, repeated questions, and longer integration timelines.

Our Solution 

  • Azure API Management Implementation: We centralized all API endpoints under Azure API Management, standardizing access, tracking, and throttling rules.
  • Security and Policy Enforcement: OAuth2 authentication, IP whitelisting, and logging policies were applied across environments for consistency and control.
  • Developer Portal Launch: A branded portal was deployed, offering self-service documentation, test consoles, and onboarding workflows for developers.
