Sempra Energy unifies its operational data with AVEVA PI System
Sempra Energy had a significant power generation footprint but needed to improve information sharing between its operating sites. Five separate SCADA systems coexisted within the group, making maintenance and upgrades costly and time-consuming, and complicating consistent reporting because the platforms were not linked. Deploying AVEVA PI System brought all the SCADA systems together and established a "single version of the truth" accessible to the entire organization. Operators and management teams now share common operational intelligence, improving data quality and responsiveness. The benefits are both operational and financial: Sempra Energy saved more than $200,000 through greater process efficiency, while improving the accuracy and reliability of reports, which is especially valuable in emergencies where every minute counts.

FAQ
How does AVEVA PI System unify five separate SCADA systems?
Sempra Energy operated five separate SCADA systems, resulting in high maintenance costs and reporting difficulties. AVEVA PI System made it possible to aggregate all 70,000 data points into a single platform accessible to the entire organization. This consolidation creates a "single version of the truth" shared by operators and management teams, reduces IT complexity and simplifies upgrades. It is a reference model for energy operators with a fragmented technical legacy.
Why is establishing a "single version of the truth" essential in data management?
When each SCADA system produces its own reports with different calculation rules, teams lose confidence in the data and spend time reconciling conflicting versions. At Sempra, AVEVA PI System creates a common repository where definitions, aggregations and indicators are standardized. This shared operational intelligence speeds up decision-making, which is especially valuable in emergencies when every minute counts. It is a fundamental pillar of digital transformation for utilities.
What financial results did Sempra Energy achieve thanks to AVEVA PI System?
Sempra Energy saved more than $200,000 thanks to the greater process efficiency enabled by AVEVA PI System. Beyond the direct ROI, the company benefits from more accurate and reliable reports, especially in emergencies. This improvement in data quality supports both regulatory compliance and operational performance. Consolidating the five SCADA systems also simplifies IT maintenance costs, generating cumulative savings year after year.
How can unified monitoring improve responsiveness in emergencies?
In an emergency (weather event, grid outage, industrial accident), the quality and speed of information are critical. At Sempra Energy, AVEVA PI System gives teams a consolidated, reliable view of 70,000 data points, where the five previous SCADA systems would have slowed down analysis. This improved responsiveness translates into faster decisions, better field coordination and less impact from incidents on the utility's end customers.
How does AVEVA PI System make upgrades easier across an industrial IT estate?
Maintaining five separate SCADA systems means multiplying contracts, training, security patches and migrations. AVEVA PI System works as a unified aggregation layer on top of existing systems: upgrades can be planned gradually without disrupting the overall view. For Sempra Energy, this architecture simplifies the technology roadmap, frees up budget for innovation and improves the company's IT resilience. It is a strategic asset for utilities with very long investment cycles.
