For a merchant owning both energy storage (such as the Ludington PSH) and a wind farm, the plots in Figs. 1 and 2 show the optimal scheduling under policy 1 and policy 2 with the initial energy in the storage of 2000 MW hours (i.e., 2 GWh) when the transmission efficiency was ρ = 0.9.The optimal decisions are made from the

A merchant ESS facility that is in the market to make a profit through energy arbitrage, buys energy during low-price hours and sells the energy back to the grid during high-price hours. The facility can be thought of as being in one of three operating modes (1) charging mode, acting similar to a dispatchable load (2) discharging mode,
These storage assets can be owned and managed by utilities, renewable energy developers, system operator or any private merchant. Intermediary storage merchant can invest on these storage assets
Energy storage (ES) systems can help reduce the cost of bridging wind farms and grids and mitigate the intermittency of wind outputs. In this paper, we propose models of transmission network planning with colocation of ES systems. Our models determine the sizes and sites of ES systems as well as the associated topology and
Recently, we published the first part of this blog series, "Unravelling the complexity of merchant energy storage projects" which compared typical fossil fuel power plants to energy storage operations in merchant markets. This post will discuss considerations for evaluating merchant energy storage projects and offer suggestions to manage risks
Abstract This paper analyzes how electricity merchants'' market impact affects merchants'' profit. Energy storage has long been studied for its role in maximizing profit, and
This paper analyzes how electricity merchants'' market impact affects merchants'' profit. Energy storage has long been studied for its role in maximizing profit, and merchant decisions are assumed
Suitably located energy storage systems are able to collect significant revenue through spatiotemporal arbitrage in congested transmission networks. However, transmission capacity expansion can significantly reduce or eliminate this source of revenue. Investment decisions by merchant storage operators must, therefore, account for the
Table 2 shows the optimal actions and profits when the wind farm merchant receives a PTC subsidy, but he or she cannot buy electricity from the grid to store (i.e., policy 2). Compared with Table 1, we find that when the subsidy is large, the profit under policy 2 may be higher, indicating that electricity merchants are willing to give up
This paper proposes an approach to assist a price-maker merchant energy storage facility in making its optimal operation decisions. The facility operates in a pool-based electricity market,
Our findings show that the State-of-Charge (SOC) based analytical solution significantly facilitates energy storage merchants'' decision-making. The SOC range is
This paper analyzes how electricity merchants'' market impact affects merchants'' profit. Energy storage has long been studied for its role in maximizing profit, and merchant decisions are assumed to have no impact on market prices. However, the trading decisions of large-scale energy storage merchants (e.g., pumped storage

Integrating large volumes of grid-scale energy storage into electricity markets, however, raises questions related to their profitability and impact on electricity prices. This paper explores the implications of different bid structures on the strategic behavior of a storage owner that participates in the wholesale market and is able to
Some researchers analyze the optimal bidding strategies of ESS owners. Reference [3] models virtual energy storages as price-makers of the market, and formulates a bi-level stochastic model to

When modeling energy storage, research into energy inventory has mainly focused on the optimal scheduling policy or on the optimal bidding decision [17]. However, most existent studies [2, 26,32
The merchant storage determines optimal bidding and offering strategies to maximize its own profits [20][21][22]. In [23], a bilevel model is proposed to investigate the optimal merchant ES

Electrical energy storage (EES) can improve the flexibility and reliability of electric power systems. At the same time, they can supply different ancillary services. The profit of the energy storage operation can be maximized by deciding the best level of each service. Merchant-owned facilities require a profit-maximizing formulation for grid

This paper presents a model to optimize merchant investments in energy storage units that can compete in the joint energy and reserve market. The proposed
For a storage-and-renewable energy source electricity merchant, we identify analytically three SOC reference points that rely on the currently available energy
We find that compared to the policy allowing merchants to buy power from the market (i.e., policy 1), which prohibits purchasing electricity from the grid, and all the energy released from the storage qualifies for the PTC (i.e., policy 2) benefits merchants'' profit when the PTC subsidy is large according to the current PTC credit rates.
As prices for energy storage (ES) decline, merchant-owned ES units have an opportunity to be profitable if they earn revenue from multiple streams. Most papers in
