welcome back to the micro grid minute
Speaker:everybody's talking about micro grids these days
Speaker:but we're gonna try to get past the buzzwords right
Speaker:you know really try to understand what's going on
Speaker:so whether you're a business owner or maybe you're
Speaker:you know leading a city or even whole municipality yeah
Speaker:you know that reliable energy absolutely is like
Speaker:it's non negotiable these days yeah
Speaker:especially when we're thinking about
Speaker:you know ways to support sustainability and also right
Speaker:and be resilient absolutely yeah
Speaker:you need energy resilience these days and you know
Speaker:it's interesting
Speaker:we're not just talking about you know backup power
Speaker:right like AJ Perkins the Microcrid mentor puts it
Speaker:microgrids are more than backup power
Speaker:they're a way for communities to gain
Speaker:energy independence and resilience okay
Speaker:so we're talking about energy independence resilience
Speaker:yeah um
Speaker:sounds like a big deal but let's break it down
Speaker:what is a microgrid so in the simplest terms
Speaker:you can think of a micro grid as like
Speaker:a mini power grid okay
Speaker:it's a self contained system that
Speaker:can power a specific area
Speaker:like a business
Speaker:campus or a hospital or even a neighborhood
Speaker:and the
Speaker:key here is its ability to operate independently from
Speaker:the main power grid okay
Speaker:what we call island mode oh
Speaker:so it's like a little power station
Speaker:exactly okay
Speaker:so what are the pieces of this power station
Speaker:so there are three main components okay
Speaker:you start with generation
Speaker:so that's where you're actually creating the power okay
Speaker:and you have a variety of sources
Speaker:you could use solar panels
Speaker:wind turbines you could have natural gas generators
Speaker:even things like hydrogen fuel cells right
Speaker:and the great thing about micro grids is
Speaker:you can mix and match these right
Speaker:to fit your particular needs so it's very customizable
Speaker:very customizable exactly great
Speaker:what about the second piece
Speaker:so the second piece is storage
Speaker:uh huh and typically this is gonna be batteries alright
Speaker:which smooth out the energy supply coming from
Speaker:you know sources that might not be constant right
Speaker:like solar and wind especially those renewable sources
Speaker:yeah so think about like a savings account for energy
Speaker:okay so you're saving energy when the sun shining
Speaker:where the wind's blowing
Speaker:and then using it later when it's not
Speaker:that's exactly right okay
Speaker:I got it what about the third piece
Speaker:the third piece is the control system okay
Speaker:and this is like the brains of the whole operation
Speaker:uh huh
Speaker:it's sophisticated software that manages the entire
Speaker:microgrid system
Speaker:and makes real time decisions about when to
Speaker:use grid power when to use stored power
Speaker:and even when to sell excess energy backed the grid
Speaker:so like a financial advisor
Speaker:kinda like a financial advisor for energy yeah
Speaker:but what are the benefits
Speaker:so I think the No.
Speaker:1 benefit that people think about is resilience okay
Speaker:so if the main grid goes down
Speaker:your micro grid keeps the lights on b
Speaker:businesses can avoid costly downtime right
Speaker:and communities can keep critical services running yeah
Speaker:we've all been there with those
Speaker:you know power outages
Speaker:power outages yeah
Speaker:they always seem to happen at the worst time
Speaker:yeah exactly right
Speaker:so it's not just about surviving outages
Speaker:it's about thriving okay
Speaker:micro grids provide reliable
Speaker:high quality power
Speaker:and they can even help stabilize the larger grid okay
Speaker:so more reliability but it's just gonna break the bank
Speaker:well AJ Perkins says
Speaker:integrating renewables into micro grids isn't just
Speaker:sustainable
Speaker:it's a smart investment that reduces costs over time
Speaker:okay so generating your own power can shield you from
Speaker:you know those rising energy costs
Speaker:yeah and if you have excess energy
Speaker:you can sell it back to the grid
Speaker:oh so you can make money
Speaker:you can turn a cost into a revenue stream
Speaker:yeah so we got resilience
Speaker:we've got reliability we've got cost savings
Speaker:anything else well
Speaker:we can't overlook sustainability right
Speaker:micro grids
Speaker:can significantly reduce your carbon footprint okay
Speaker:which is something that customers
Speaker:investors regulators
Speaker:everybody's looking at these days
Speaker:so it's not just good for the planet
Speaker:it's good for business absolutely
Speaker:now are all micro grids created equal
Speaker:that's a great question and the answer is no
Speaker:there are different types of microgrids okay
Speaker:we have level 1 microgrids
Speaker:which are the simplest
Speaker:these are typically for a single building
Speaker:like you might have solar panels on the roof of your
Speaker:business that's considered a level 1 microgrid
Speaker:then we have level 2 microgrids
Speaker:which cover multiple buildings like a campus or
Speaker:you know part of the utilities network
Speaker:and these can use multiple energy sources
Speaker:got it so they offer a bit more flexibility
Speaker:and then the most complex type is a level 3 micro grid
Speaker:right which can encompass an entire community wow
Speaker:so this is a more sophisticated system yeah
Speaker:with diverse energy sources
Speaker:and might even integrate smaller micro grids
Speaker:so let's say I'm sold I want a micro grid
Speaker:where do I even begin well
Speaker:the first step is to really understand
Speaker:your energy needs okay
Speaker:what are your current energy costs
Speaker:your usage patterns
Speaker:and what are your sustainability goals
Speaker:uh huh and that's where working with experts comes in
Speaker:so don't try to DIY this yeah
Speaker:I mean you could try okay
Speaker:but you really need expert guidance from engineers
Speaker:contractors consultants who specialize in microgrids
Speaker:okay to assess your needs
Speaker:they can design a solution that works for you
Speaker:and they can navigate all the complexities of
Speaker:the project so get help
Speaker:get help that's the message I'm hearing you
Speaker:and that brings us to you know
Speaker:choosing the right integrator for your project hmm
Speaker:but before we dive into that
Speaker:let's take a quick pause
Speaker:we'll be back in a moment
Speaker:to talk about how to find the right partner
Speaker:to make your micro grid vision
Speaker:a reality sounds good
Speaker:so we're talking to those integrators right
Speaker:yeah the expert
Speaker:the expert
Speaker:so what does a micrograde integrator actually do
Speaker:they are like the architects
Speaker:and the construction managers
Speaker:yo of your microgrid project okay
Speaker:they bring everything together okay
Speaker:from designing the system
Speaker:and selecting the technologies yeah
Speaker:to overseeing the installation
Speaker:and even handling the ongoing maintenance

Speaker:you know the regulations
Speaker:all the permitting the financing wow
Speaker:everything so how do I find a good one
Speaker:how do I know who to trust
Speaker:you know that's a great question yeah
Speaker:because there are a lot of
Speaker:companies out there these days that are saying
Speaker:they're microgrid experts right
Speaker:but I think the most important thing is experience okay
Speaker:how many microgrid projects have they completed
Speaker:what's their track record
Speaker:so don't go with a newbie
Speaker:I mean if you wanna be
Speaker:you know a Guinea pig right
Speaker:you can but maybe not yeah
Speaker:I would stick with somebody
Speaker:who's got a lot of experience okay
Speaker:what else should we look for
Speaker:their technology partnerships okay
Speaker:are they working with reputable manufacturers
Speaker:and suppliers
Speaker:are they on the cutting edge of micro grid technology

Speaker:embracing things like artificial intelligence
Speaker:and advanced control systems
Speaker:because this field is constantly evolving right
Speaker:so you need somebody
Speaker:who's up on all the latest and greatest
Speaker:absolutely okay
Speaker:and of course regulatory knowledge is crucial right
Speaker:make sure the integrator
Speaker:understands the rules and the permitting processes
Speaker:specific to your area
Speaker:so you need someone who knows the lay of the land
Speaker:absolutely and understands all the rules and rigs yes
Speaker:what about the human element
Speaker:oh that's really important too okay
Speaker:you're gonna be working very closely with these people
Speaker:right
Speaker:so you need a good fit in terms of communication style
Speaker:you know their overall approach yeah
Speaker:you need to get along with these folks
Speaker:you need to have a good relationship with them right
Speaker:um so yeah
Speaker:take your time do your research
Speaker:talk to multiple integrators before you make a decision
Speaker:so don't just jump in no
Speaker:you wanna really vet these companies okay
Speaker:um choose a partner that you trust
Speaker:and you feel comfortable collaborating with
Speaker:that's good advice hmm hmm
Speaker:now I think
Speaker:everybody listening would love to hear some stories
Speaker:about micro grids
Speaker:in action sure yeah yeah
Speaker:what are some real world examples of how this stuff
Speaker:is working yeah
Speaker:so there's this really cool example okay
Speaker:of a rural community in a mountainous region okay
Speaker:and they were really struggling with frequent power
Speaker:outages and they decided to implement a micro grid
Speaker:okay
Speaker:that combines solar and wind power with battery storage
Speaker:okay and the result was they increased their resilience
Speaker:they lowered their energy costs
Speaker:and they gained a newfound sense of energy independence
Speaker:wow
Speaker:so they're really taking control of their energy future
Speaker:exactly and it shows you
Speaker:how microgroups can really empower communities
Speaker:even in you know
Speaker:remote locations that's awesome
Speaker:do you have any other example
Speaker:yeah I mean
Speaker:there's a hospital complex in a Hurricane prone area
Speaker:okay that was really concerned about power outages
Speaker:disrupting you know
Speaker:critical care right
Speaker:so they installed a micro grid okay
Speaker:with a combination of natural gas
Speaker:generators and battery storage okay
Speaker:and now they can weather even the most severe storms
Speaker:okay
Speaker:and they can ensure continuous power for life saving
Speaker:medical equipment and patient care
Speaker:so it really is you know
Speaker:a life or death situation
Speaker:absolutely in some cases yeah
Speaker:where these microgrids can really be a game changer

Speaker:and one that will explore in more detail
Speaker:after a quick break
Speaker:we'll be back in a moment to discuss
Speaker:you know the exciting innovations that are shaping
Speaker:the future of micro grids okay
Speaker:and what they mean for businesses and communities
Speaker:like yours welcome back to the micro grid minute
Speaker:so before the break
Speaker:we were talking about the future of micro grids yeah
Speaker:it's gonna be interesting to see how things evolve yeah
Speaker:so what's on the horizon
Speaker:what are some of those exciting innovations
Speaker:well one trend that I think is really fascinating is
Speaker:the rise of artificial intelligence
Speaker:okay and machine learning AI
Speaker:yeah AI in micro grid control systems
Speaker:so micro grids that think for themselves
Speaker:that's a good way to put it
Speaker:yeah imagine a system that can predict energy demand
Speaker:okay optimize energy use
Speaker:and even diagnose potential problems before they occur
Speaker:so it's like preventative maintenance
Speaker:yeah it takes efficiency
Speaker:and reliability to a whole new level
Speaker:so that's pretty SCI fi it is
Speaker:but it's becoming a reality
Speaker:that's awesome
Speaker:what else can these AI powered microgrids do
Speaker:well they can actually participate in energy markets
Speaker:really so
Speaker:they can sell energy back to the grid
Speaker:when it's most valuable wow
Speaker:and they can provide grid services
Speaker:like voltage support and frequency regulation
Speaker:so they can actually make the grid more stable
Speaker:exactly for everybody
Speaker:yeah they can be a real asset for utilities
Speaker:okay especially as we move toward a more decentralized
Speaker:energy system right
Speaker:and you mentioned something earlier called
Speaker:virtual power plant yes yes
Speaker:what are those so a virtual power plant
Speaker:or a VPP
Speaker:is basically a network of distributed energy resources
Speaker:okay so things like solar panels
Speaker:wind turbines battery storage systems
Speaker:all working together like a coordinated team
Speaker:so see a really big micro grid
Speaker:you could think of it that way
Speaker:yeah microgrids can actually be building blocks of VPPs
Speaker:okay so
Speaker:they can
Speaker:aggregate and coordinate these distributed resources
Speaker:got it to provide those grid services
Speaker:and participate in those energy markets
Speaker:that's pretty cool
Speaker:and how do electric vehicles fit into all of this
Speaker:that's a great question because
Speaker:as we see more and more electric vehicles on the road
Speaker:VPPs with integrated microgrids are gonna be crucial
Speaker:okay for managing that increased demand on the grid
Speaker:it sounds like
Speaker:micro grids are gonna play a really important role
Speaker:absolutely in the future of energy
Speaker:they're not just about you know
Speaker:going off the grid they're about creating a smarter
Speaker:more sustainable and more resilient energy ecosystem
Speaker:and I think AJ Perkins really sums it up well
Speaker:when he says the real strength of a micro
Speaker:grid lies in its flexibility
Speaker:to adapt to local energy needs
Speaker:while supporting the larger grid
Speaker:that's a great quote mmm hmm
Speaker:so for our listeners who are excited about micro grids
Speaker:what should they do next I would say
Speaker:reach out to those experienced micro grid integrators
Speaker:we talked about yeah
Speaker:get help get help
Speaker:they can guide you through the process
Speaker:from assessing your needs
