Be careful, not everyone is as they seem

California State Contractors License Board (CSLB):

  • CSLB urges consumers to follow these tips when

dealing with a building contractor:

  • Hire only licensed contractors and ask to see the

license.

  • Verify the contractor's license by checking
  • nline at www.cslb.ca.gov
  • Don't rush into decisions and don't hire the first

contractor who comes along.

  • Don't pay more than 10 percent down or

$1,000—whichever is less.

  • Don't pay cash, and don't let the payments get

ahead of the work.

  • Get three bids, check references, and get a

written contract.

  • Contact CSLB if you have a complaint against a

contractor.

Clean Coalition (non-profit)

Mission To accelerate the transition to renewable energy and a modern grid through technical, policy, and project development expertise. Renewable Energy End-Game 100% renewable energy; 25% local, interconnected within the distribution grid and ensuring resilience without dependence on the transmission grid; and 75% remote, fully dependent on the transmission grid for serving loads.

Community Microgrids are the grid of the future

A Community Microgrid is a new approach for designing and

  • perating the electric grid, stacked with local renewables and

staged for resilience.

Key features:

  • A targeted and coordinated distribution grid area

served by one or more substations – ultimately including a transmission-distribution substation that sets the stage for Distribution System Operator (DSO) performance.

  • High penetrations of local renewables and other

distributed energy resources (DER) such as energy storage and demand response.

  • Staged capability for indefinite renewables-driven

backup power for critical community facilities across the grid area – achieved by 25% local renewables mix.

  • A solution that can be readily extended throughout a

utility service territory – and replicated into any utility service territory around the world.

Value of Resilience (VOR)

  • Everyone understands there is significant value to resilience provided by indefinite

renewables-driven backup power

  • But, nobody has yet to quantify this value of unparalleled resilience.
  • Hence, there is an economic gap for innovative Community Microgrid projects while learning is

still is the early stages.

  • The Clean Coalition aims to establish standardized Value of Resilience (VOR) for critical,

priority, and discretionary loads that will help everyone understand that premiums are appropriate for indefinite renewables-driven backup power of critical loads and almost constant backup power to priority loads, which yields a configuration that delivers backup power to all loads a lot of the time

  • The Clean Coalition’s VOR approach will establish

standardized values for resilience of three tiers of loads:

  • Tier 1 are mission-critical and life-sustaining loads,

crucial to keep operational at all times, including during grid outages. Tier 1 loads usually represent about 10% of the total load.

  • Tier 2 are priority loads that should be maintained as long as long as

doing so does not threaten the ability to maintain Tier 1 loads. Tier 2 loads are usually about 15% of the total load.

  • Tier 3 are discretionary loads make up the remaining loads, usually

about 75% of the total load, and are maintained when doing so does not threaten the ability to maintain Tier 1 & 2 loads.

Goleta Load Pocket (GLP)

The GLP is the perfect opportunity for a comprehensive Community Microgrid

  • GLP spans 70 miles of California coastline, from Point Conception to Lake Casitas,

encompassing the cities of Goleta, Santa Barbara (including Montecito), and Carpinteria.

  • GLP is highly transmission-vulnerable and disaster-prone (fire, landslide, earthquake).
  • 200 megawatts (MW) of solar and 400 megawatt-hours (MWh) of energy storage will

provide 100% protection to GLP against a complete transmission outage (“N-2 event”).

  • 200 MW of solar is equivalent to about 5 times the amount of solar currently deployed in the GLP and

represents about 25% of the energy mix.

  • Multi-GWs of solar siting opportunity exists on commercial-scale built-environments like parking lots,

parking structures, and rooftops; and 200 MW represents about 7% of the technical siting potential.

  • Other resources like energy efficiency, demand response, and offshore wind can significantly reduce

solar+storage requirements.

Direct Relief Microgrid is a perfect case study

  • Location: Santa Barbara, CA.
  • Owner: Direct Relief (one of

the largest disaster recover/supply non-profits in the world).

  • Brand new 155,000-square-

foot pharmaceutical warehouse.

  • Ships direct to disasters

zones, internationally. Cold storage cannot be without power.

  • Needed a microgrid for

indefinite renewables- driven backup power.

  • Has a microgrid with net

zero solar plus about 2 hours of storage.

  • Has a diesel generator

backup to the backup that is almost never used beyond the maintenance routine required every couple weeks.

Direct Relief Microgrid limited to onsite resilience

320 kW PV 676 kWh Li 600 kW diesel generator with 4,000 gallon tank

  • Resiliency is #1 concern:
  • 320 kW PV
  • 676 kWh Storage
  • 600 kW generator
  • 4000 gal. of fuel
  • PV annual generation

designed to cover annual consumption.

  • Storage designed to time-

shift the generation to more valuable times, and provide Resiliency.

  • Genset provides “back-up to

the back-up”.

  • Direct Relief Microgrid

requirement is that the critical loads are operational indefinitely, even through local disasters that causes long-term interruptions to normal electricity service.

Direct Relief is ready to do way more!

Microgrid only serves Direct Relief needs:

  • 70% of roof and 100% of

massive parking area solar potential is unused.

  • Additional storage not

able to be considered due to policy prohibitions around exporting energy from a battery to the grid – even though the energy is 100% stored solar.

Ready to do way more::

  • 1,133 kW in total solar

siting potential, 427 kW more rooftop and 386 kW in parking lots.

  • Existing switch gear is

already sized for the expansion and is just awaiting the policy innovation!

Residential solar+storage microgrid example

  • 10 kW solar + 20 kWh storage
  • $60k total cash price:
  • $3,000 per kW for solar (requires about 650 square feet,

which is approximately equivalent to 25 x 25 feet).

  • $1,500 per kWh for storage and microgrid controller etc.
  • $40k net cash price after approximately $20k in

near-term incentives:

  • $15k from 26% Investment Tax Credit (ITC) on total price

(requires storage to be charged by solar only).

  • $5k Self Generation Incentive Program (SGIP) on storage.
  • $175k in savings over 30 years
  • $4k in first year savings.
  • Over 10% Internal Rate of Return (IRR) over 30 years.
  • 45 cents/kWh = SCE’s 30-year Levelized Cost of Electricity

(LCOE) with 3% annual escalator.

  • 10-year simple payback without any SCE escalator.
  • Resilience for free!

Most recent incentive was a one-time payment of 25 cents/watt hour So, for a 13.5 kWh battery, a $2,900 Incentive was recently available. Incentive levels decrease as more people subscribe.

  • 1. Provides cleaner, lower cost energy than the grid
  • 1. Keeps you indefinitely powered during a grid outage
  • 1. Contributes to the emergence of a better (more sustainable

A home with “200a main panel”, could consume up to 48kW! Practically installing solar mean you need less storage... Practically, just back-up your “critical loads”... A big home could easily consume > 40kWh/day!

EMERGENT MICROGRID

A Technical “Day in the Life” of an ESS + PV

Solar Production: Powers house and charges battery instead of exporting power at low rates. Edison “peak” price Battery Exports to Grid Battery Charges from PV

How long will my BATTERY last if “in hours”?

Setting: Energy Conservation Setting: Max Usage Setting: Business As Usual

Assuming NO Solar

How long your battery lasts depends on how fast you use it up. Depending on use- case, an ESS lasts about:

  • 21 hours at “base load” usage
  • 14 hours at “normal usage”
  • 4 hours during “max usage”

Technical : “Why Lithium”

  • It is “Good Enough”...
  • Prices are dropping fast.
  • It is “Scaling”...

In 2015: only three “megafactories” were planned (including Tesla’s “gigafactory”): In 2019: 68 megafactories, with a total capacity of 1.45TWh are projected to be on line by 2028.
