10 Operational Challenges of Running a Battery Asset in ISO/RTO Markets and How to Solve Them

Battery energy storage systems (BESS) have rapidly become essential to supporting ancillary services and renewable integration. However, entering the ISO and RTO wholesale markets as a storage asset operator is no simple task. From compliance to forecasting, the gap between commissioning and cash flow is wider than most developers expect. For BESS owners, developers, and investors, understanding and managing the complexities of market operations is critical to realizing profit and avoiding costly penalties. SYSO helps projects close that gap by handling market registration, real-time dispatch, and revenue optimization across PJM, ISO-NE, MISO, CAISO, NYISO, SPP, and ERCOT. Below are the ten most common challenges in the market today, and how we solve them for our clients.

1. Market Registration and Qualification

Each ISO/RTO has its own regulations and requirements pertaining to battery assets. These requirements are complex and require detailed planning from the commencement of your project. Missing just one form or failing to establish telemetry can delay market entry by months and leave revenue on the table. SYSO handles the full registration stack, from interconnection coordination to system enrollment. We can also act as a registered market participant on your behalf, helping to accelerate the registration process.

2. State of Charge (SOC) Optimization

Managing your battery’s SOC in real time is critical to capturing value during scarcity events when real-time prices elevate. Misalignment between dispatch and energy availability can compromise arbitrage value or capacity obligations, which can trigger steep penalties. This is where active scheduling and predictive analytics make a difference.

3. Performance Penalties for Non-Compliance

Markets like PJM and ISO-NE issue significant penalties for assets that underperform during critical hours. Capacity revenue can be clawed back if your battery is unavailable or misaligned with dispatch windows. SYSO mitigates this risk with 24/7 monitoring and pre-event readiness checks. 

4. Telemetry Infrastructure

Inadequate telemetry and control infrastructure is a common weak point for BESS developers. Real-time data (often at second intervals) is required for participation in ancillary services, energy, and capacity markets. SYSO provides SCADA integration and Remote Terminal Unit (RTU) coordination to ensure market compliance.

5. Revenue Stack Complexity

Each market offers different value streams, from energy arbitrage and ancillary services to capacity payments. Chasing one stream, however, can cannibalize another. SYSO designs revenue stack strategies that prioritize high-margin windows and align with regulatory requirements. 

6. Regulatory Shifts and Compliance Ambiguity

Market rules evolve constantly. Whether it’s ELCC changes in CAISO, evolving NERC reforms for IBRs, or DNE Dispatch in ISO-NE, staying current is a full-time job. SYSO tracks rule changes and adapts asset strategy in real time to maintain market eligibility.

7. Interconnection Risk

Many assets face delays or curtailment risk due to system constraints. Flexible interconnection design and site-specific dispatch can reduce impacts, but only if planned early in the project. SYSO advises clients from the design phase to align interconnection timing with market revenue potential.

8. Forecasting and Day-Ahead Market Participation

Day-ahead bidding requires accurate forecasting of prices, demand, and renewable output. Underperformance can lead to invoice imbalances or missed pricing peaks. SYSO’s proprietary, data-driven models optimize daily strategy based on market-specific behavior.

9. Asset Availability and Outage Coordination

Even a short unreported outage can result in BESS capacity reduction. ISOs and RTOs require proper notification for both planned and forced outages. SYSO manages these communications to ensure asset performance is preserved.

10. Cybersecurity and Data Compliance

Modern batteries are data-intensive assets that are subject to cyberattacks and data breaches. SYSO ensures secure telemetry pathways, compliance with system requirements, and redundant monitoring to avoid data disruption.
