Imagine your energy storage systems working like a well-rehearsed orchestra—every instrument (or storage node) plays its part at the right time, in the right place. That''s what proxy energy storage address technology achieves.
Simulation results show that the proposed proxy signature mechanism can achieve the delegation of digital signature power under the premise of security and reliability, which is suitable for the management model of SES on blockchains.

While arbitrage revenues could only cover a fraction of the costs of energy storage in past years, we show that proxy storage PPAs have the potential to foster unsubsidized energy storage installations in Europe within the next decade, especially when the storage is charged from the electricity grid or from co-located wind energy generation assets.
This paper designs a subscription configuration mode in which the ETCES operator aggregates and subscribes to the idle capacity of independent energy storage system (ESS) suppliers flexibly.

Abstract: Sharing energy storage (SES) is a novel business model in order to increase the profits and improve the utilization rate of idle energy storage facilities.
Energy Price Volatility Management: Storage PPAs provide fixed or predictable pricing, helping off-takers manage energy price fluctuations and improve budgeting.
The electro-thermal cloud energy storage (ETCES) is a novel business model that aggregates distributed energy storage resources within a unified cloud-based platform and provides multi-energy storage services to distributed energy systems (DES).
While arbitrage revenues could only cover a fraction of the costs of energy storage in past years, we show that proxy storage PPAs have the potential to foster unsubsidized energy storage installations in Europe within the next decade, especially when the storage is charged from the electricity grid or from co-located wind energy generation assets.
Projections are considered for renewable energy generation and for electricity market prices to assess the future revenues of proxy storage PPAs and their uncertainty. This determines the future role of proxy storage PPAs in light of decreasing cost of energy storage.
From the energy buyer perspective, the cash flows of proxy storage PPAs are based on the revenues of the optimal operation of a virtual energy storage technology (with predefined characteristics) on the day-ahead market.
We propose a contractual setup, the proxy storage power purchase agreement (PPA), to foster the deployment of energy storage technologies. We define a threshold price below which the PPA becomes financially attractive for PPA buyers. We compute the threshold price for several storage technologies and configurations, in seven European countries.
On the other hand, the revenues of proxy storage PPAs are based on perfect foresight, hence it may not be achieved due to forecasting uncertainty in the day-ahead market (Zucker et al. estimate that around 80% of the revenues with perfect foresight can be harnessed (Joint Research Centre and Institute for Energy and Transport et al., 2013)).
Such threshold prices overlap with the best-case forecast of the battery levelized cost of storage in 2030, indicating that proxy storage PPAs can play a role in enabling battery storage installations within the next ten years in Europe (generating about €180 million per year).
