Energy Storage Controls

The project's operating system, known as the energy management system (EMS), assumes responsibility for controlling (charging and discharging), optimizing (revenue and health), and ensuring safety (electrical and fire). The EMS operates in conjunction with the inverters, battery management system (BMS), breakers, and fire system to coordinate their functions. However, what occurs in the event that it does not yield satisfactory results?

The financial strategies for utility-scale Battery Energy Storage Systems (BESS) are greatly influenced by the unique characteristics of the regions in which providers establish themselves. Typically, players in this sector opt for a revenue stacking approach, which involves aggregating incomes from multiple sources. They may engage in supplementary offerings, arbitrage, and capacity auctions. For instance, numerous BESS installations in the United Kingdom presently focus on ancillary services like frequency regulation. In Italy, there are talented players who have achieved success by emerging victorious in one of the country's capacity auctions that prioritize renewable energy. On the other hand, in Germany, the focus is more on evading expensive grid enhancements in order to seize opportunities. The successful players in the FTM utility sector have recognized the importance of tailoring their approach to individual countries and their regulations, rather than relying on a singular, all-encompassing strategy.

To gain a comprehensive understanding of the potential advantages that come with BESS, it is ideal to divide the market based on user applications and sizes. Within BESS, there are three distinct segments: front-of-the-meter and BTM residential installations, typically ranging below 30 kWh (as shown in Exhibit 1).

In order to monitor battery readings, the SCADA system generally establishes direct communication with the BMS. Additionally, there may be a need or advantage for the SCADA system to communicate with DC-DC converters, inverters, and auxiliary meters in order to effectively manage the BMS.

The main clientele for FTM installations consists of utilities, grid operators, and renewable developers who seek to address the sporadic nature of renewables, offer grid stability services, or avoid expensive investments in their grid. Typically, the BESS providers in this sector are either vertically integrated battery manufacturers or prominent system integrators. They will set themselves apart based on factors such as price and scope, dependability, their history of successfully managing projects, and their aptitude for creating energy management systems and software solutions for grid optimization and trading.

Promote the development of robustness within supply chains. Numerous essential components of BESS (from battery cells to semiconductors in inverters and control systems) depend on intricate supply chains that are vulnerable to disruptions arising from various factors such as scarcities of raw materials and modifications in regulations. When establishing a supply chain strategy, it is important to take into account various factors such as strategic partnerships, multi-sourcing, and local sourcing. Additionally, planning for potential technological changes should not be overlooked. In addition to addressing BESS components, those operating in the industry also face challenges when it comes to engineering, procurement, and construction (EPC) capability and capacity, especially for front-of-the-meter applications. To achieve smooth execution of BESS projects, it is imperative to establish strategic collaborations with prominent EPC companies that have the capacity for large-scale BESS installations.

As the next stage of objectives outlined in the Paris Agreement draws near, governmental bodies and various organizations are actively seeking to enhance the uptake of renewable energy sources. Certain regions, heavily reliant on energy consumption, offer additional incentives to encourage the exploration of alternatives to conventional energy methods. In Europe, the motivation arises from an energy crisis, while in the United States, it originates from the Inflation Reduction Act, a legislation passed in 2022 that designates $370 billion for clean-energy investments.

Additionally, there are the tasks related to system integration, encompassing the comprehensive planning and creation of energy management systems and additional software to enhance the adaptability and utility of BESS. We anticipate these integrators to capture an additional 25 to 30 percent of the profit allocation accessible.
