EMS & Energy Optimization
An EMS decision does not start with choosing software: it starts with defining the objective and control logic by which consumption, generation and storage will be managed together. Afectus is on the independent advisory side — we do not sell our own EMS software; we define the control strategy and requirements, and verify them independently of any vendor.
Which facilities this is for
- Facilities with solar and/or storage and several flexible loads
- Companies managing multiple sites from a single center
- Facilities planning an EMS investment that want an independent requirements definition
- Operations not getting the expected benefit from their existing automation
How We Build the Strategy
It starts from the objective, not from product selection: first the control objective, then the control logic, then verification.
Data Inputs
- 15-minute consumption, generation and, if any, storage data
- List of shiftable / curtailable loads and their flexibility limits
- Tariff structure and peak / price components
- Existing control rules and setpoints (if any)
- Grid connection capacity plus process and comfort constraints
Data is validated before analysis; flexibility assumptions on paper are confirmed with on-site measurement.
Model and Scenarios
- Control objectives are defined: self-consumption, peak limiting, price-based operation, backup
- Rule-based and optimization-based control logic are modeled separately
- Consumption, generation and storage are simulated together in a single dispatch model
- Portfolio-level coordination is evaluated for multiple facilities
Deliverables
- Control strategy and logic definition
- EMS functional requirements list — for tender evaluation
- Strategy comparison and expected impact ranges
- Multi-facility optimization plan
Assumptions and Limits
EMS benefit depends on measured flexibility; flexibility on paper looks larger than the actual benefit until verified on site.
We define the strategy and requirements; because real performance depends on operation and asset response, no savings guarantee is given.
Optimization is bounded by physical and contractual constraints: connection capacity, process and comfort limits cannot be exceeded.
More automation is not always better; some strategies deliver benefit at a disproportionate increase in complexity.
Common Mistakes
Buying an EMS product before defining the control objective.
Optimizing a single asset (only the battery, or only solar) instead of the system as a whole.
Ignoring process and comfort constraints, producing strategies operators override.
Assuming a single control strategy fits every tariff and price regime.

Sample Analysis
Below, the qualitative effect of four control strategies is compared on the same facility profile. The values indicate direction; actual impact is modeled from the facility's data and flexibility profile.
EMS Control Strategy Comparison
Sample Scenario
| Strategy | Primary objective | Self-consumption effect | Peak effect |
|---|---|---|---|
| Self-consumption priority | Use solar on site | High | Medium |
| Peak limiting | Cap peak demand | Medium | High |
| Price-based | Charge when cheap, discharge when expensive | Variable | Low |
| Hybrid (rule + optimization) | Balance objectives together | High | High |
This is a sample scenario; it indicates qualitative direction and cannot be used on its own as an investment or control decision.
Related questions
No. We don't sell equipment, batteries, or materials, and we don't take on turnkey contracting or field installation. We stay on the owner's side and build the technical and financial basis for a decision — implementation is carried out by the supplier or contractor you choose. This separation keeps our analysis free of any obligation to defend a particular product or contractor.
Our Energy Intelligence scope spans BESS investment feasibility, solar/load analytics, EMS optimization, and energy procurement advisory — we model consumption, generation, and price data together.
EMS Strategy Consultation
The output is not a product recommendation but a requirements list. We review your consumption, generation and on-site asset data, identify the control objective that fits your facility, and itemize the functions to require from an EMS — independently of any vendor.
