Power utilities globally are experiencing the most significant transformation in their industry since their inception nearly 150 years ago. The ideas of decarbonization and asset democratization are gaining traction in the energy supply sector. Concurrently, the digitalization of the grid—along with evolving regulatory demands—presents new challenges and opportunities for utilities worldwide.
Many utilities encounter a unique dilemma: enhancing customer engagement and retention. Historically, interactions between customers and utilities have been less than favorable, often limited to basic services like connecting or disconnecting service, sending monthly bills, or providing outage updates.
In various regions, utilities aim to generate new revenue streams beyond simply selling electricity. Achieving this requires a deeper understanding of consumers and their energy usage patterns. It’s essential to establish an effective customer engagement mechanism that resonates with today’s energy consumers: for instance, “Alexa, pay my energy bill,” “Alexa, why is my energy bill so high?” or even “Alexa, charge my EV at 7:30 p.m. or whenever electricity is cheapest.”
Going further, utilities aspire to provide customers with actionable insights through Alexa skills. For example: “Hi, John. I’ve noticed that your air conditioner is underperforming. Would you like me to arrange maintenance with [utility name]?” Such interactions can significantly enhance customer loyalty to their utility providers.
Intel and Amazon Web Services (AWS) are dedicated to delivering the necessary tools, platforms, and services to realize these capabilities. This article introduces the concept of Energy IoT.
Intel is recognized as an AWS Partner Network (APN) Advanced Technology Partner with the AWS IoT Competency.
Opportunities in Energy IoT
The widespread availability of internet connectivity and advancements in cloud computing have accelerated the evolution of the Internet of Things (IoT), leveraging data collection from edge devices and cloud-based data analysis. This has given rise to new applications and services across various sectors, including consumer, commercial, and enterprise.
In the energy sector, it is now feasible to utilize energy disaggregation algorithms to analyze the energy consumption behavior of individual appliances by examining their primary power signal.
This Energy IoT framework offers opportunities for solution providers and utility companies to deliver enhanced services to consumers:
- Energy Usage Advisory: Providers can offer detailed energy consumption insights, including appliance-specific spending breakdowns, alerts for inefficient usage or faulty appliances, and tailored recommendations for optimizing energy use.
- Demand Response/Energy Efficiency Programs: Utility companies can predict energy demands by analyzing historical and current consumption data. Customers can be alerted to reduce non-essential appliance usage during peak demand, conserving energy and preventing grid brownouts. Participants in these programs may receive rebates.
- In-Home Monitoring for Seniors: Consider an elderly parent living alone. Relevant parties can be promptly notified of unusual energy usage or atypical appliance behavior, such as a microwave remaining unused beyond its normal downtime.
The technical solutions for these services can be implemented cost-effectively and at scale using edge devices powered by Intel’s System on a Chip (SoC) field programmable gate array (FPGA) technology alongside software components hosted on the AWS Cloud.
Solution Architecture
Energy IoT solutions predominantly follow an “edge-to-cloud” architecture, comprising on-premises edge devices interfacing with cloud-based software functions.
In this setup, the edge devices act as “energy gateways” installed in individual homes, responsible for:
- Data Acquisition: Monitoring main power lines to collect real-time high-frequency power signal samples.
- Data Transmission: Securely and efficiently transmitting measured power data to the cloud.
The energy gateway may also communicate with smart appliances (e.g., Wi-Fi-enabled lamps or smart thermostats) to control or adjust their functions based on commands from the cloud.
In the cloud, data from each household is processed through the following workflow:
- Saved to a database.
- Forwarded to a real-time visualization application.
- Processed through a data analytics pipeline for energy disaggregation.
Additionally, the energy gateway can expose an API, allowing third-party applications to access data. This is particularly valuable for utility companies focusing solely on data aggregation, as they can partner with others for energy disaggregation analytics and derive insights from the data.
Energy Gateway Utilizing Intel CycloneV SoC FPGA
For mass deployment in households, the energy gateway must be low-cost, lightweight, and have low power dissipation to comply with the thermal requirements of household power panels. The Intel CycloneV SoC FPGA meets these criteria while delivering the necessary performance for the energy gateway.
An FPGA is an integrated circuit that can be programmed to execute digital logic and machine algorithms at high speeds. Intel’s family of SoC FPGAs integrates FPGA fabric with a host processor on a single chip, and the CycloneV series strikes a remarkable balance between performance, thermal efficiency, and cost for embedded hardware.
Specifically, the CycloneV FPGA fabric supports high accuracy and rapid sampling across two simultaneous analog-to-digital channels, making it ideal for data acquisition and processing from power lines.
Software can be executed on the CycloneV host processor to manage application logic and facilitate cloud communications via its built-in Ethernet interface or external Wi-Fi and Bluetooth connections.
Processing Energy Data with AWS
The AWS Cloud provides the scalability, security, and reliability essential for Energy IoT solutions. Furthermore, AWS offers various building blocks that streamline the creation of data pipelines for processing, storing, and analyzing IoT data.
These components include:
- AWS IoT Core: A service for secure data transport and control commands between the gateway and cloud, including the deployment and execution of AWS Lambda functions at the gateway.
- Amazon S3: A data storage service for incoming data and file hosting.
- Amazon Kinesis Data Firehose: A buffering and data forwarding service that enhances data ingestion for real-time analytics.
Understanding these services can empower professionals in various fields; for example, this is an excellent resource for those interested in career development in the tech sector, especially through sites like Career Contessa.
In conclusion, the integration of Intel’s SoC FPGA technology with AWS services presents a promising frontier for enhancing customer engagement and operational efficiency in the energy sector.
