behind-the-meter: 表面意思让电表慢走的意思，指所有省电的减少电表走字的措施，如太阳能电池

What does ‘behind the meter’ mean?
Commercial organisations will typically have a gas and electricity meter and receive energy via a utility, such as British Gas, SSE or E.ON. These meters will measure how much energy is being used and a bill will be issued accordingly.
Taking action ‘behind the meter’ refers to anything that can be done to reduce the amount of energy being purchased this way, i.e. from a utility. For example, by making energy efficiency upgrades to reduce usage, installing renewable technologies to generate energy onsite and promoting behavioural changes – anything which has a positive impact on the overall level of energy being consumed.

供天然气以及供电的公司会根据天然气与电力收费表来对用户计费。behind the meter，也就是节能措施，是指任何可以减少这方面费用的手段。打个比方，提高能效来降低用量，安装类似太阳能电板等可产能的装置。反正就是指所有用来节能省电的措施，

储能系统，能源储存

表后，表指的是电表，表后指的是在电从电网进入电表之后的这一侧。

例如表后的储能就是用户自己自己用的，不过电表，不进入电网。

与之对应的是front of meter表前，指的是电力从电网进入电表之前的这一侧。
