The CAISO regulatory committee is responsible for maintaining the reliability and accessibility of one of the largest and most modern power electrical grids in the world. In addition to traditional power generation plants, many privately owned and operated solar photovoltaic (PV) systems supply power for grid availability. CAISO maintains an exacting process to both gain access to, and continue to participate in, California’s open energy market. Nor-Cal Controls helps you comply with CAISO NRI, RIG, and metering guidelines. We also offer an open-source code that allows you to receive and react to CAISO ADS instructions for other power generation requirements.
CAISO Remote Intelligent Gateway (RIG)
Generation facilities that want to interconnect at the transmission level must install and maintain a field Remote Intelligent Gateway (RIG) unit that can interface with an operator’s system to supply required data to the California Independent System Operator (CAISO). Nor-Cal’s team of dedicated and experienced engineers have integrated several independent operator systems into the CAISO grid with the use of the CAISO certified Orion LXm from NovaTech; full configuration, testing and startup services are included in the turnkey CAISO RIG package.
Accurate metering of electricity generated provides critical data to allow for power generation accuracy. This ongoing direct measurement allows CAISO to manage and monitor power generation in real-time, ensuring the stability of the grid. Nor-Cal can provide all required metering equipment, configuration and associated tasks related to CAISO requirements for new generators.
CAISO New Resource Implementation (NRI)
A total of over forty (40) steps spanning more than two hundred (200) days must be taken and approved by CAISO to gain full energization. Nor-Cal will work concurrently with site asset-owners and CAISO to ensure specific telemetry, metering and RIG documentation requirements are met in a timely fashion during this NRI timeline. Submittals are critical to the NRI timeline; to avoid potentially costly delays in energization, and ensuring focus on asset owners ‘time to market’ approach for their investment.
Nor-Cal is a certified RIG provider through CAISO, and can provide the following expertise to ensure a successful project:
- CAISO NRI Process Management
- RIG equipment, configuration, testing and certification with CAISO
- CAISO approved metering equipment, configuration, testing and certification with CAISO
Complete Every Milestone in CAISO Bucket System
Before you can sync or interconnect your utility-scale solar plant to California’s whole transmission grid, you need to complete all the critical milestones in the CAISO bucket process:
Bucket 1: 203 Days Before Sync
To participate in California ISO or the state’s open energy market, you need to submit documents necessary for your full network model preparation.
Bucket 2: 105 Days Before Sync
At this stage, you need to get the regulatory contracts started and submit the necessary information for ISO forecasting.
Bucket 3: 30 Days Before Sync
The Bucket 3 deliverables need to be accepted a month before the estimated sync or implementation date. These deliverables include a letter of intent, generator resource data templates (GRDT), scheduling coordinator selection and acceptance letters, and metering, telemetry, and RIG engineering requirements.
Bucket 4: 10 Days Before Sync
Once you’ve submitted all the deliverables for buckets 1 to 3, it’s time to submit a request for trial operations, which includes a preliminary validation of meter data.
Bucket 5: 1 Day Before Sync
One day before the sync date, your scheduling coordinator must contact the ISO outage management for subsequent testing and synchronization.
Bucket 6: Commercial Operation Date
Once your application is approved, you will receive a Certificate of Compliance. Then you can request a commercial operation date, so you can start distributing solar energy to homes and offices in California.
Count on us to help your solar plant comply with CAISO requirements and get interconnected to the state’s power transmission grid successfully.
CAISO Support Complete with Open-Source Solutions
Submission of requirements in every CAISO bucket is critical to the start of your facility’s commercial operations. We’re here to make sure your solar PV plant is integrated into a topnotch RIG unit and metering equipment. Our engineers are trained to do testing and configuration on such equipment. Through our CAISO support services, we will help your plant achieve CAISO compliance and hit every milestone in the CAISO bucket.
Above all, our team provides energy solutions with open architecture design. Working with us means no service contracts at the end of the project. Plus, anything we install in your solar facility can be boosted or integrated with third-party software or hardware, reducing the total cost of ownership and increasing your plant’s ROI.
Work with us today. We’ll help prepare your solar facility for commercial operations, making sustainable energy easily accessible to more homes and businesses in California.
