ERCOT Market Operations
A Level 4 QSE Built
for the ERCOT Market
SYSO is an ERCOT Level 4 Qualified Scheduling Entity running 24/7 dispatch, telemetry, real-time bidding, and settlements for battery storage, solar, and wind across ERCOT’s energy-only, RTC+B market.
Supporting 6+ GW across 300+ renewable and storage assets in power markets across North America
ERCOT is an energy-only market that just raised the bar
ERCOT operates an islanded, energy-only grid serving about 90% of Texas load, with no centralized capacity market to fall back on. Revenue comes entirely from energy and ancillary services, and the RTC+B redesign now co-optimizes both in real time. That rewards fast, well-telemetered assets and penalizes anyone whose bids, data, and dispatch fall out of sync.
No centralized capacity market. Assets earn from energy and ancillary services alone.
A self-contained Texas grid carrying roughly 90% of the state's electric load.
Energy and ancillary services are now co-optimized in real time, raising the operational bar.
ERCOT leads the nation in grid-scale battery storage, and the fleet keeps growing.
Operations for every asset class in ERCOT
Battery storage, solar, and wind each face their own revenue mix, telemetry demands, and RTC+B strategy in ERCOT. Choose your technology to see how SYSO operates it.
Every ERCOT asset needs a QSE. You have three paths.
A Qualified Scheduling Entity is the required operational and financial interface between your asset and ERCOT's markets, submitting bids, holding telemetry, executing dispatch, and settling. As both a Level 4 QSE and a qualified QSE Agent, SYSO can support you on any of the three.
Become a QSE
Hold your own Level 4 registration and run market operations in-house, including a fully staffed 24/7 center and real-time telemetry.
Engage a QSE (Turnkey)
SYSO becomes your Level 4 QSE and assumes the full market-facing operation, no upfront buildout in qualification, staffing, or telemetry.
Hybrid (QSE Agent)
You hold the QSE registration and keep direct market standing while SYSO runs the 24/7 NOC, telemetry, and dispatch as your QSE Agent.
The SYSO advantage in ERCOT
Whatever you operate, the foundation is the same: SYSO holds the highest ERCOT certification, runs the control room, and knows the RTC+B rulebook cold, so you don't have to build any of it.
ERCOT Level 4 QSE
The highest qualification tier ERCOT recognizes, authorizing full participation across the energy and ancillary services stack for physical assets.
Qualified QSE Agent
If you hold your own registration, we operate as your QSE Agent, providing the 24/7 staffing and telemetry infrastructure behind your market standing.
SYSO-Owned 24/7 NOC
A NERC-CIP compliant Network Operations Center, owned and staffed by SYSO around the clock. Never outsourced, never business-hours only.
Built for RTC+B
Automated real-time bidding and co-optimization strategy tuned for the new market design, so bids, telemetry, and dispatch stay in lockstep.
Telemetry to ERCOT
Continuous, high-quality real-time telemetry, engineered and validated by our own team, the data foundation RTC+B dispatch depends on.
Settlements & Compliance
Financial settlement with ERCOT, protocol compliance through every market change, and clear, API-first reporting for owners, lenders, and investors.
Frequently asked questions
High-level questions about ERCOT and how SYSO operates assets within it. For technology-specific detail, see the BESS, solar, and wind pages.
What is a QSE, and why does my ERCOT asset need one?
A Qualified Scheduling Entity is the required operational and financial interface between your generation or storage asset and ERCOT's wholesale markets. Without a QSE, an asset cannot submit bids or offers, receive or respond to dispatch instructions, or settle financially with ERCOT. The QSE handles bidding, telemetry, real-time communications, protocol compliance, and settlements, 24/7.
What is a Level 4 QSE, and why does it matter?
ERCOT qualifies QSEs across four levels. Level 4 is the highest tier and is required to fully represent physical generation and storage resources in the energy and ancillary services markets. It demands a fully staffed 24/7 operations center, proven real-time communications, robust telemetry, financial assurance, and completion of ERCOT's testing process. SYSO holds Level 4 certification.
What are my options for participating in ERCOT?
There are three paths: become a QSE yourself, engage a third-party QSE that assumes the full market-facing operation (the most common path for renewable and storage owners), or take a hybrid approach where you hold the QSE registration while a qualified QSE Agent runs the operationally intensive functions. The right choice depends on your portfolio size, timeline, existing infrastructure, and financing structure. SYSO supports all three.
What is RTC+B, and how does it affect my asset?
Real-Time Co-Optimization Plus Batteries co-optimizes energy and ancillary services together in the real-time market, replacing the static Day-Ahead ancillary procurement and the ORDC with Ancillary Services Demand Curves that price shortages dynamically. Batteries are modeled as unified assets providing load, generation, and reserves at once. It rewards fast, accurately telemetered assets and penalizes misaligned bids or dispatch, making automated bidding effectively required.
Does SYSO operate solar, wind, and storage differently in ERCOT?
Yes. The operational foundation, QSE representation, telemetry, 24/7 dispatch, and settlements, is shared, but each technology has its own revenue profile. Battery storage centers on arbitrage and the co-optimized ancillary stack; solar on nodal price and basis exposure with curtailment management; wind on production forecasting and congestion risk. See the technology pages for the full detail.
