RENEWABLE POWERBattery Energy Storage Systems for Mines

Hatch worked with a Battery System

Vendor to complete detailed engineering

for the installation of a 300kW/1.2MWh

Battery Energy Storage System at 2 test

locations.

Battery Energy Storage Systems improve the performance and efficiency of

islanded diesel and Wind/Solar-diesel Hybrid Systems.

Islanded Diesel Systems can be improved by permitting the diesel generators to

operate at maximum efficiency while a Battery Energy Storage System regulates

the grid frequency and acts as a spinning reserve. This operating regime

maximizes the utility of the most efficient and easily maintained diesels and

thereby lowers operating costs.

Islanded Wind/Solar-Diesel Hybrid Systems with Battery Energy Storage Systems

improve performance by turning off unnecessary diesels, when clean power is

available. The result is improved stability of the islanded grid with lowered

diesel operating cost. A Battery Storage System allows more renewable

generation, by ramp rate control, thereby further lowering power generation

costs.

Hatch develops innovative solutions that meet unique site requirements to

reduce energy operating costs. Short payback periods are achieved by optimal

sizing and selection of energy storage devices.

Hatch’s expertise in Power Generation and Distribution System Design provides

lower risk in a rapidly developing energy storage technologies environment.

(Over)

Diesel fuel cost savings can offset the capital and running costs of a wind-diesel-battery

hybrid retrofit project. Hatch has global experience in designing hybrid power systems.

Hatch worked with Barrick to design a

1MW/4MWh Battery Based Solar

Islanded Grid for a remote location.

RENEWABLE POWER

Hatch’s detailed integration study for the

Inuit village of Kangiqsualujjuaq in

Canada’s arctic north involved a diesel

plant retrofit with wind turbines and

flywheel energy storage system

ENERGY STORAGE SYSTEMS CONTINUED

• Why not a typical lead acid battery? - Low life under constant cycling, large

and heavy. Most vendors only supply batteries and not a system.

• Which vendor/battery do I pick? Each battery technology has its nuances

which are advantages or disadvantages depending on the application and size.

• Can I use vendor controls for my application? – do they do what I want?

• Should I use a flywheel over a battery? – better for a large number of smaller

energy/power discharge cycles but may not provide the required energy.

• What about lithium-ion battery fires? – We understand that battery

management control systems and thermal management are key factors that

impact the safety of larger Li-ion battery systems.
