The frameworks in this slide deck can help those in the power sector understand and analyze key power system design criteria, different constructs for future utility business models, and evaluation criteria for the different utility business model constructs. SEPA developed a set of frameworks to help synthesize the collective insights gathered from Phase III of the 51st State Initiative
Global energy demand is expected to increase by 30 percent between 2018 and 2040, the equivalent of adding another China and India to our planet.1
Renewable energy sources will help meet that demand and will require not one, but a robust mix of energy storage technologies to lower the planet’s carbon footprint, create efficient energy models and stabilize the grid.
Dropping investment costs are causing new companies to sprout up every day and lower energy pricing is putting even more pressure on renewable energy asset managers to squeeze every dollar out of their budgets and save their margins. Renewable asset management software can help asset owners and operators grow their portfolios in an increasingly complex environment. This guide will walk readers through the essentials of renewable asset management software including misconceptions about asset management, the benefits of software, and how to recognize when you need it. The guide will also give common renewable asset management scenarios and workflows that can be automated or benefit from an asset management software solution.
The addition of energy storage to an existing or new utility-scale PV installation allows system owners and operators the opportunity to capture additional revenues. Traditional storage plus solar applications have involved the coupling of independent storage and PV inverters at an AC bus or the use of multi-input hybrid inverters. An alternative approach – coupling energy storage to PV arrays with a DC-to-DC converter – can help maximize production and profits for existing and new utility-scale installations. DC-Coupled Utility-Scale Solar Plus Storage leads to higher round-trip efficiencies and lower cost of integration with existing PV arrays and at the same time, opens up new revenue streams not possible with traditional AC-coupled storage, including clipping recapture and low voltage harvesting, while being eligible for valuable tax incentives.
Key highlights from the report include:
• Long-duration storage is now commonly viewed as having an energy delivery time of at least four hours, and the need for it is growing.
• Renewable energy self-consumption is seen as the most promising application for long-duration storage.
• A Levelized Cost of Storage (LCOS) calculation is considered the most reputable selection criterion in determining which long-duration storage technology to deploy.
• The most promising technology for long-duration storage is flow batteries and the key criterion for selecting a given asset is cost, particularly the capital expense required.
Most forms of infrastructure are being transformed with modern monitoring, data communication, data analysis, and remote control systems. The electric transmission system is poised to be the next sector. A number of proven, advanced technologies exist which can help optimize the existing transmission grid. These technologies can variously allow hidden transmission capacity to be identified and utilized, reduce power flow on overburdened lines, and/or reconfigure existing grid elements to optimize various operational scenarios. These advanced technologies can be applied singly or in combination.
Researchers from NREL and Clean Energy Group found that placing a monetary value on the ability of solar+storage to avoid losses during grid outages can significantly impact project economics and system design. Using data from Southern California Edison, researchers analyzed the economic case for solar+storage for three customer types (school, office building, and hotel) in Anaheim, California. In each case analyzed, larger PV and battery storage systems were found to be economical when the value of resilience is accounted for.
