I renamed this function to specify elec storage. The constraints should also be updated to loop b in p.s.storage.types.elec instead hardcoding "ElectricStorage". Like H2 MG state of charge constraint below.

is leakage typically measured by the hour?

I'll suggest a rename to soc_self_discharge_rate_fraction and capacity_self_discharge_rate_fraction - do we want to include this for all storage techs and zero it out by default? That's what I'm currently implementing; to avoid a breaking change maybe we keep the thermal TES field alone for now and save that for a future update.

| thermal_decay_rate_fraction::Float64 = 0.0004 # Thermal loss (gain) rate as a fraction of energy storage capacity, per hour (frac*energy_capacity/hr = kw_thermal) | ||
| soc_based_per_ts_thermal_decay_fraction::Float64 = 0.0 # Thermal loss (gain) rate as a fraction of the energy stored in each timestep (frac*energy_stored = kw_thermal) |

"loss (gain)" and "loss/gain" are a bit confusing. I would just call it energy loss
| installed_cost_per_gal::Float64 = 1.50 # Thermal energy-based cost of TES (e.g. volume of the tank) | ||
| thermal_decay_rate_fraction::Float64 = 0.0004 # Thermal loss (gain) rate as a fraction of energy storage capacity, per hour (frac*energy_capacity/hr = kw_thermal) | ||
| soc_based_per_ts_thermal_decay_fraction::Float64 = 0.0 # Thermal loss (gain) rate as a fraction of the energy stored in each timestep (frac*energy_stored = kw_thermal) | ||
| capacity_based_per_ts_thermal_decay_fraction::Float64 = 0.0004 # Thermal loss (gain) rate as a fraction of the installed storage capacity per timestep (frac*energy_capacity = kw_thermal); the provided default is for an hourly thermal loss/gain |

also I think these field names need to be updated to ...self_discharge...
