ANSI SCTE 246:2018 pdf download.Energy Management Subcommittee.
The scope of the operational practice covers grid tied and grid independent solar photovoltaic systems deployed in cable operator ‘s infrastructure.
1.3. Benefits
Solar PV systems are expected to have a 20 plus year lifecycle and maintaining the deployment can help optimize performance. Conditions such as soiling should be addressed according to this operational practice to both support energy production and reliability. Where the system is deployed as part of power availability strategy, Ibliowing the outlined operational practice should help ensure the quoted power output is produced during time of critical need.
1.4. Intended Audience
Solar PV system owners and facility managers should familiarize themselves with this operational practice.

7. O&M and the Financing of PV Assets
An effective O&M program enhances the likelihood that a system will perform at or above its projected production rate and cost over time. Therefore, it reinforces confidence in the long-term performance and revenue capacity of an asset. Historically, O&M practices and approaches have not been standardized, and instead, they were implemented in various proprietary methods. This approach can increase the cost to projects and portfolios, as well as raise the perception of risk from investors. Specific recommendations from the PV O&M Working Group to reduce variations in O&M practices include:
• Define performance metrics uniformly. A system characterized by a guarantee to deliver 1 ,000 MWh/year would be difficult to compare and bundle with another that has a guarantee to be operational 90% of the time. Investors need performance metrics and evaluation methods to be the same across a bundle of assets.
• Refer to specified standards. Practices and delivery of O&M services also differ, and investors need to know that an existing system has been maintained according to standard definitions and criteria.
• Make cost estimates uniform and predictable. Differences in types of systems and also geographic location and climate conditions can confound securitization. Investors want to know how much it will cost to perform required O&M and secure the performance of the investment. Cost estimates must be uniform and predictable so that they can be bundled, yet they should reflect the factors that cause O&M costs to vary from site to site.ANSI SCTE 246 pdf download.
