Battery Storage Energy Management

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.

Large-scale deployments of BESS are already underway, with the notable involvement of FlexGen company in a project aiming to establish a BESS capacity of six GWh in due course. A different United States-based company, involved in various industries including energy, has already exceeded that milestone by achieving 6.5 gigawatt-hours (GWh) in deployments of battery energy storage systems (BESS) in the year 2022. A significant portion of the current influx of funding towards BESS is being allocated to services aimed at enhancing the flexibility of energy providers, such as firm frequency response. Over time, the main source of BESS (Battery Energy Storage System) expansion will arise from the development of solar parks and wind farms, requiring batteries to manage their storage requirements for shorter durations.

Recognize a neglected requirement within the value chain. In an emerging industry like this, it is beneficial for companies to consider additional products and services they could expand into, either through internal growth or mergers and acquisitions. As an example, is there any hindrance preventing a system integrator from conducting in-house battery packaging? Or collaborating with a battery manufacturer to jointly develop a new cell chemistry? Moreover, is there any limitation preventing a battery manufacturer from incorporating system integration or service capabilities to attract a particular BESS sector, like utilities?

BESS EMS, when contrasted with solar SCADA, presents considerably greater complexity. Several owners have come to realize this through personal experiences that were challenging. The EMS assumes a significant level of accountability in relation to its cost, particularly for projects exceeding 100 MWh in size. In such cases, there are two cost metrics that are taken into consideration.

The last section of the C&I subsegment encompasses challenging settings, including mining, construction, oil and gas exploration, as well as outdoor festivals. The driving force behind its expansion will be customers shifting from diesel or gas generators towards eco-friendly options like BESS and hybrid generators in order to mitigate emissions. One of the primary catalysts for the increasing adoption in this sector is the implementation of forthcoming regulations, such as the European Commission's sustainability-driven Big Buyers initiative and Oslo's objective to achieve net zero on construction sites by 2025. A significant number of companies transitioning to more environmentally friendly practices will initially opt for hybrid genset solutions as an intermediate step before fully transitioning to Battery Energy Storage Systems (BESS).

Given these circumstances, it is highly probable that sodium-ion batteries will gain a larger portion of the BESS market. In fact, it is anticipated that a minimum of six manufacturers will commence production of sodium-ion batteries in 2023. Evidently, healthcare providers will need to make choices regarding which technology to invest in. Integrators may consider configuring their systems in a manner that simplifies the transition to sodium-ion batteries once they become readily accessible.

If the project consists of multiple inverters, then only one inverter and its corresponding batteries are required for step 6. As a result, the remaining components of the project can continue functioning with a partial outage while the full outage, lasting two weeks, is solely necessary for the completion of step 7.

Energy Storage Software

The advancements in technology are driving the growth of the market for battery energy storage systems (BESS). Battery storage plays a crucial role in supporting the generation of renewable energy, facilitating alternative sources to consistently contribute to global energy requirements despite the inherently unpredictable nature of these sources. As battery prices decrease, the versatility offered by BESS (Battery Energy Storage System) will become crucial in various areas such as peak load management, optimizing self-consumption, and providing backup power during power disruptions. These applications are progressively gaining profitability.

The commercial and industrial (C&I) sector, which ranks as the second-largest category, is projected to experience a compound annual growth rate of 13 percent according to our forecasts. This growth should result in annual additions ranging from 52 to 70 GWh by 2030 for the C&I sector.

Critical readings that are transmitted from the batteries/stacks comprise state of charge (SOC), electrical current, voltage, temperature, as well as the quantity of interconnected stacks and alarm indicators. In the case of battery issues such as excessive heat or failure to charge adequately, the SCADA system has the capability to notify plant operators through an alarm displayed on the human-machine interface (HMI).

Battery Storage EMS

The battery management system (BMS) is frequently mistaken for the EMS. The BMS is a straightforward system that serves two purposes: 1) enabling or disabling battery operation and 2) ensuring the safety of the batteries. When initiating a BESS, the EMS will instruct the BMS to activate the batteries (establish the DC bus). The BMS will execute this command only if it detects a safe condition. During operation, if the BMS detects parameters that are exceeding their acceptable range, it will prompt the EMS to decrease power output (in cases where parameters breach fault thresholds, the BMS will activate the opening of rack contactors).

The market for BESS (Battery Energy Storage Systems) is currently experiencing a rapid phase of growth and development. Companies that fail to take action at this pivotal moment risk losing out on significant opportunities. Success in this market will be determined by four essential factors that companies must demonstrate. As the energy transition gains momentum, these victors will generate value in an emerging market.

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).

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.

From a technological standpoint, the primary factors that customers prioritize when it comes to batteries are cycle life and cost-effectiveness. Presently, lithium-ion batteries are prevailing because they fulfill customer requirements. In the past, the dominant choice for battery chemistry was a nickel manganese cobalt cathode. However, lithium iron phosphate (LFP) has emerged as a more cost-effective alternative, surpassing it in popularity. (Customers of lithium iron phosphate are willing to acknowledge that LFP may have certain limitations compared to nickel batteries, particularly in terms of energy density.) Nevertheless, the scarcity of lithium has led to the exploration of various intriguing and promising battery technologies, with a particular focus on cell-based options like sodium-ion (Na-ion), sodium-sulfur (Na-S), metal-air, and flow batteries.

C&I is divided into four subsegments, with the initial one being electric vehicle charging infrastructure (EVCI). According to the McKinsey Center for Future Mobility, electric vehicles (EVs) are projected to experience a significant increase in market share, rising from approximately 23 percent of global vehicle sales in 2025 to 45 percent by 2030. This rapid growth will necessitate the widespread expansion of standard charging stations and superchargers, thereby exerting strain on existing grid infrastructure and requiring expensive and time-consuming upgrades. In order to prevent this situation, charging station companies and owners might choose to install a Battery Energy Storage System (BESS) on their premises. Collaborations have already been established between BESS providers and electric vehicle manufacturers to construct additional Electric Vehicle Charging Infrastructure (EVCI), even in secluded areas.

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?
