Engineering at Geli
We work in two-week sprints with teams focusing on data science, our on-prem software, and the cloud-based services. We try to knock out well-defined epics across teams that complete in system integration testing. Our feature delivery process involves developing in our test environment, SIT on stage, and deploying to production. All stories undergo a PR review with a focus on clean, well tested and documented code. Our development tools include Bitbucket, Git, Jira, and Jenkins.
Regarding the organizational structure, our VP of Engineering sets our high-level goals, the product manager helps prioritizes business needs and scopes epics, and tech leads help supporting members of their team with design and guidance.
Over the last couple of months, we transitioned from running our algorithms on-premises to shifting the compute-heavy workloads to the cloud running on Kubernetes and making heavy use of messaging with RabbitMQ. Along with this development, there has been a rapid proliferation of micro-services such as a service that provides historical and forecasted weather data to our nodes, and a market connector that fetches wholesale electricity prices from various markets and sends that to our optimizers. We are in the early stages, and there are plenty of cloud infrastructure challenges ahead.
On the algorithmic side, the work done by the cloud infrastructure team has provided the opportunity to utilize more resource intensive algorithms. We are transitioning away from deterministic to stochastic optimization. This is not only an intriguing optimization problem but also an exciting forecasting challenge as we need to forecast distributions and generate multiple scenarios that accurately encapsulate the cost distribution.
Centralize the forecasting and optimization algorithms in the cloud! Currently, there are long-running processes that shadow each physical site. We want to move to a model in which a central forecaster and optimizer solves jobs for all sites which allows us to use a better, more expensive solver, is easier to maintain and provides better resource utilization.
Improve our simulation infrastructure! Presently, we use Airflow with ECS workers but would like to transition to running it all on EKS for better performance and resource utilization. Additionally, we would like to gain more insights into the data which requires storing more meta-data and deriving value through reports and dashboards.
Scale our data pipeline capabilities! We are constantly adding more and ever larger sites to our platform which our IoT device telemetry collection, processing, and persistence need to keep up with. This includes evaluating different messaging protocols (e.g. Kafka) and time-series databases as well as improving the ingestion, processing, and retrieval of telemetry (e.g. reactive streams).
Improve our probabilistic forecasts! Our ability to save money for our customers is a direct consequence of the load and solar generation forecasting accuracy. We are always innovating in the field by prototyping novel algorithms.
Build our Virtual Power Plant offering! So far, our main focus has been on optimizing
behind the meterenergy management for individual sites. There are more interesting use-cases coming up that require aggregating multiple sites and biding their capacity into marketplaces and utility programs like demand response.
