This paper explores the impacts of energy policies for supporting low-carbon infrastructure on the economic and financial performance of energy storage when coupled with a generator. The study sets in the UK context, and the unit of analysis is the generator connected with energy storage. An analytical method is derived to assess the impact of policy schemes for low-carbon infrastructure on energy storage. The case study of energy storage systems coupled with a Small Modular nuclear Reactor (SMR) is quantitatively investigated in three scenarios: 1. SMR-only (the baseline); 2. SMR with thermal energy storage; and 3. SMR with Lithium-ion battery. For the strike price at 100 £/MWh, the net present value for Cases 2 and 3 reduces by 32% and 400%, respectively, when the energy storage capacity increases from 100 MWh to 1 GWh. As the net present value reduces with increased energy storage capacity (when coupled with generation), this work shows that low-carbon incentives are, unintentionally, barriers to the development of energy storage due to: (A) current generator incentives give a favourable return on investment and energy storage would diminish it; (B) energy storage cannot participate in generator only incentives.

本文探讨了支持发电机的能源政策对支持低碳基础设施的经济和财务绩效的影响。该研究以英国为背景，分析单位是与储能相连的发电机。推导了一种分析方法来评估低碳基础设施政策计划对储能的影响。在以下三种情况下，对与小型模块化核反应堆（SMR）耦合的储能系统的案例研究进行了定量研究：1.仅SMR（基准）；2.带有热能存储的SMR；3.带锂离子电池的SMR。对于100英镑/兆瓦时的行使价，当储能容量从100兆瓦时增加到1吉瓦时时，情况2和3的净现值分别减少32％和400％。随着净现值随着储能容量的增加（与发电结合）而降低，这项工作表明，低碳激励措施无意地成为了储能技术发展的障碍，原因是：（A）当前的发电机激励措施带来了有利的回报投资和储能将减少投资；（B）储能不能仅参与发电机激励。
