What is a virtual power plant (VPP)?Ī VPP is an aggregation of DERs that can be dispatched and traded in energy markets as a unit. EaaS is essentially a PPA in which a third party owns a microgrid, and you pay the operational costs as a fixed price for energy over time. Microgrid owners also can enter into PPAs to sell their unused energy to companies or utilities. Renewable energy developers commonly sell power through PPAs to achieve a return on their infrastructure investment. The buyer may be an energy supplier that resells the power or a company with significant energy requirements, or a need to reduce its carbon footprint. What is a power purchase agreement (PPA)?Ī PPA is an agreement to sell energy at a predetermined price. By connecting a microgrid to the utility grid as a DER, you can help increase the role of renewables on the grid and improve grid resilience. To do this seamlessly, the microgrid should be integrated with the utility’s automation systems at the substation and distribution levels. A microgrid controller automatically connects and disconnects these from the macro grid by remotely opening or closing a circuit breaker or switch. How can microgrids connect to the grid, and what are distributed energy resources (DERs)?ĭERs are power resources outside a central grid, including microgrid generation and storage systems. Schneider Electric can even transfer the asset to a partner when necessary, reducing your financial risk. This gets the microgrid up and running faster and protects you from utility rate hikes. With EaaS, partners like Schneider Electric, through their Joint Ventures with AlphaStruxure, GreenStruxure, and GreenNext, build, own, and operate a microgrid at your site for a long-term price per kWh. What is Energy as a Service (EaaS)?ĮaaS is a business model that lets your organization reap the benefits of microgrid ownership without the cost and risk of capital investment. A microgrid can be a long-term hedge against inflation as the cost of fossil-fuel utility plants increases relative to renewable sources. It allows you to use your own loads without paying peak rates from the utility and the option to sell excess power when available. How does a microgrid aid in energy cost efficiency?Īn intelligent microgrid controller determines the optimal times to consume, produce, store, or sell energy based on weather, predicted utility rates, and other factors. With the right software, controller, and interconnection equipment, the microgrid can use renewable sources, including battery storage, to supply your needs and could enable providing decarbonized power through a utility to other users. How does a microgrid help with sustainability goals?Ī microgrid provides the technical infrastructure to pilot, integrate, and scale renewable energy systems in lieu of or to balance out non-renewable sources from the grid at your own pace. If the grid fails, a microgrid controller can sense the disruption, disconnects from the utility, activates “island mode,” and reconnects when the utility service is restored. A microgrid enables your organization to remain powered by seamlessly switching to on-site generation or storage. Utility outages are growing more prolonged and frequent in many areas, often caused by weather-related disasters and aging infrastructure. How does a microgrid help with resilience? This can be a complex undertaking, so finding the right partner is essential for success. An intelligent microgrid that automatically adjusts energy loads and resources to optimize cost and resilience requires a full stack of generation, storage, analytics, interconnection, and software components. It can be as small as a few solar panels and a battery or as large as an array of solar, wind, hydrogen, and other systems across multiple facilities or a community. In this blog, I’ll introduce microgrids, their benefits, and some useful terms for understanding this transformative approach to energy.Ī microgrid is a set of on-site energy loads and resources that work as a system and can operate independently of the grid. A microgrid can help your organization achieve its goals and control its energy future – with or without capital investment. Enterprises are more motivated than ever to control energy costs and increase sustainability, while the utility grids they rely on grow more vulnerable due to aging infrastructure, extreme weather, and rising energy demand.
