Hatch worked with a battery vendor to complete engineering for 300kW/1.2MWh battery energy storage systems at two mine test locations. Battery energy storage improves performance and efficiency of isolated diesel and wind/solar-diesel hybrid power systems by allowing diesel generators to operate at peak efficiency and providing frequency regulation and spinning reserve. It also improves stability and lowers costs for hybrid systems by turning off unnecessary diesels when clean power is available. Hatch develops optimized energy storage solutions to reduce operating costs with short payback periods.

1. RENEWABLE POWER
Battery 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.

2. 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.
