Energy Resiliency Through Technology    

Electrical Engineer

Solar 

The costs of solar PV have dropped considerably
over the last ten years and will likely continue to do
so, opening the technology up to a wider customer and geographical base in the process. Although most solar systems are grid-tied, control technology can enable a distributed solar energy system to “island” during an event to provide power to the site when the grid is down. And unlike traditional fuel-based backup generators that are only called on during emergencies, solar systems can provide energy cost savings over their entire time. Pairing solar with energy storage creates a powerful solution for resiliency by storing and dispatching solar energy through major events, even when the sun is not shining.

Energy Storage

Like solar PV, battery energy storage systems – lithium- ion based, in particular – have dropped significantly in cost, creating new opportunities for organizations to manage energy in response to grid conditions and to store bulk energy for use during power shortages. As utilities launch dynamic pricing schemes and expand on demand response programs, additional revenue streams are emerging that will help pay for battery energy storage systems that also provide resiliency benefits. “Plug-and-play” systems, or pre-programmed energy storage systems that can optimize distributed resources without significant integration costs,

promise to unlock new opportunities for customers
to take advantage of distributed generation and
boost resiliency. In addition, energy storage’s short construction timeline, small footprint, and modular design allow for projects to be scaled readily to meet a wide range of customer types and applications.

Microgrids 

Microgrids enable an energy user (or several contiguous energy users) to optimize multiple
energy assets and island from the grid during power disruptions through sophisticated control technology. Through a microgrid, energy users can have the best of both worlds by remaining connected to the grid most of the time while also ensuring a power supply during outages. There is no fixed suite of technologies that constitutes a microgrid; today, many legacy microgrids are powered by diesel generators, though natural-

gas powered CHP and a variety of solar-plus-storage solutions are becoming increasingly common power solutions. The combination of distributed generation plus microgrid controls can help optimize performance and cost for large energy users pursuing more resilient energy infrastructure.

Combined Heat and Power (CHP)

Many large energy users have on-site generators, powered by natural gas, renewable gas, diesel, or other fuels. CHP systems go beyond traditional on-site generation by recovering the waste heat created by turbines and reciprocating engines for valuable end uses, such as hot water, that can be used for industrial applications, wastewater treatment, personal use,

etc. The result is a much more efficient system that also reduces an organization’s dependence on utility- supplied electricity for its energy and hot water needs. (Tri-gen systems add chilled water capability that can be used to supply air conditioning and refrigeration.)

Given today’s relatively low natural gas prices across many parts of North America, CHP is an attractive and efficient alternative for large-scale industrial customers.

What Resort Energy Does

We research, access funds and plan to seamlessly incorporate renewable energy, energy storage, and dispatchable generation into your property.  

 

The microgrid functions in parallel with the utility to provide energy savings. It also gives you the ability to enter island mode during grid outages to provide complete reliability and resiliency.

We provide your resort and possibly your community with ready-to-go energy access for the independence, resilience, and sustainability you need.

Project Assessment 

 The first step is to conduct a feasibility assessment. This will help uncover a system’s potential benefits, challenges and life cycle, with a unique site in mind. Financial, resiliency and sustainability opportunities will all vary from place to place.

It can be easy to overlook details at the beginning of the process, but missed details often result in increased costs and project delays.

System Eligibility

The next step (although it often happens in conjunction with the feasibility assessment) is to complete a 30% system design. This involves laying out the basic types and sizes of technologies involved, their intended locations, the methods for interconnecting them within a microgrid and a plan for working with the local utility. The goal here is to help set the course for future detailed design considerations

Financial Planning 

Before beginning the full design process, it is also crucial to conduct financial planning and develop a cost estimate for the project. These are critical to a system’s feasibility and can illuminate opportunities for third-party financing. It is important to lay out all budgeting guidelines, so as to accommodate such assistance and equipment purchasing.

Project Management

Being vendor agnostic allows our team to bid projects and access competitive market pricing. We then screen contractors, negotiate contracts and oversee your projects from concept to completion. We also offer ongoing reporting and asset management.

Full Design 

Once these steps have been taken and the logistics of the system have been determined, it is time to carry out the full design, moving forward from 30% to complete blueprints and documentation, including a utility interconnection agreement.
